In 1990 Maxim was retained by the Town of Wainwright, Alberta
to provide engineering design services for a new subdivision.
The project began with a servicing study for a proposed 180
hectare residential and commercial development at the east end
of the Town. The study involved a detailed analysis of the
existing water supply, sanitary sewer, and storm water
drainage systems to determine their capacity to accommodate
post development demands.
Storm water management was a particularly high priority in the
servicing study. Development of the new subdivision would
increase the rate of runoff to two of the Town's storm
drainage systems. One was already overloaded; therefore a
parallel storm sewer was designed to raise the system's level
of service to an acceptable standard. The other system would
carry runoff from most of the proposed development, and would
be affected significantly by the increased rate of runoff.
Two storm water detention ponds were included in the storm
system design of the new subdivision, to reduce the rate of
outflow to the existing system to a manageable level.
Subsequent to the servicing study, Maxim performed the
detailed design of underground services, drainage systems,
and road work for the first four phases of the new
development. They include approximately 150 residential lots
as well as commercial property.

2. MULTI-FAMILY HOUSING DEVELOPMENTS - ALBERTA
Maxim personnel provided the engineering design, field layout
and construction supervision services for the site grading,
sanitary sewers, water mains, asphaltic concrete pavement
(with concrete curb and gutter) and storm sewers for several
multi-family housing developments such as the 70 Unit
Development, 56 Unit Development, 22 Unit Development and
42 Unit Development all in Castledowns.
Our office completed the pre-design of Stage I and II of a
400 Unit Development in South Ridge (Huntington Hill) and
was involved in the construction phase of Stage I for 100
Units of the Huntington Hill Development.
A subsequent project included design and construction of
Phase II -- 112 units and for Phase III - 32 units. Both
phases included special designs for retention of storm water
on the new parking lots, and restriction of outflow rates
to the existing City system.

3. WHITEMUD DRIVE DRAINAGE DESIGN
Maxim personnel were retained by the City of Edmonton to
design the storm water drainage system for Whitemud Drive
between 99 Street and 106 Street. The design required the use
of the Storm Water Management Model SWMM3 and a detailed
analysis of the drainage pattern of the land within and
adjacent to the proposed freeway, to determine the potential
volume and rate of runoff which could flow into the depressed
Whitemud freeway. Due to limited excess capacity in the
existing storm sewer system, a 10,300 m cubed underground
storage vault was designed to retain excess runoff.
The storage vault is located beneath the roadway, and consists
of a flat plate roof system, interior columns, and a raft type
foundation system. Construction was carried out in six
different "segments", producing a storage reservoir
approximately 44 m x 66 m x 5 m high. Construction involved
over 3700 m cubed of cast-in-place concrete, and approximately
300,000 kg of epoxy coated and normal reinforcing steel.
Interior and exterior waterproofing was also provided.
A "hydrovex" flow restriction device and a gate valve system
were included in the design to control the rate of outflow to
the existing storm sewer after the storm has subsided. The
depth of the existing receiving sewer necessitated the design
and construction of three new "drop manholes". Water
entering each manhole plunges down to 20 m through a drop
shaft into a lower chamber. The lower chamber has a
cast-in-place wall whose height and position are specially
designed to reduce the kinetic energy of the storm water prior
to entering the receiving sewer. Construction of the drainage
system was completed in late 1993.
Client: The City of Edmonton
Year: 1989 - 93
Cost: $3.3 Million
4. CITY OF EDMONTON - MILL WOODS DRAINAGE STUDY
The City of Edmonton, Environmental Services Department,
commissioned Maxim personnel to investigate and make
recommendations which would rectify basement flooding in
the Greenview subdivision of Mill Woods. The study required
the review of street drainage and ponding, cross filtration
between storm and sanitary sewers, determination of ground
water infiltration and infiltration through foundation weeping
tile. The alternative solutions included the installation of
an additional pipe system, surface or underground storage
and/or elimination of infiltration at the source. The initial
report documented the frequency and volume of extraneous flow
resulting from rainfall, presented alternative remedial
measures.
A second phase included the installation of basement sump
pumps in existing homes which interrupted weeping tile flow
for discharge to the ground surface outside the home. Our
program included data recorders and telemetry systems for
remote retrieval of sump pump operating records, and
installation of sewage flow and level recorders. The analysis
of data utilized the Storm Water Management Model program to
simulate the sewer system flow conditions. It was calibrated
to previous storm events, and used to estimate hydraulic grade
lines for future design storm events. The result of data
analysis was that storage of extraneous flows was a more
efficient solution in Greenview than intercepting flows with
sump pumps.
Client: The City of Edmonton
Year: 1989 - 92
5. 153 AVENUE DRAINAGE DESIGN
The City of Edmonton Works Department, retained Maxim to
design the stormwater drainage system for a 1.5 kilometre
section of 153 Avenue between Fort Road and 18 Street. The
new roadway intersected two natural drainage basins; thus
both overland and roadway drainage had to be accommodated.
Overland stormwater flows to had to be limited to
pre-development levels, and surface storage was incorporated
to meet this objective. A 10,000 m cubed stormwater retention
pond was designed to intercept both natural and roadway
overland flow for release to the roadway piped system
following storm dissipation. This facility included full
flow control complete with telemetry tied to the receiving
stormwater trunk sewer flows.
Roadway drainage to the 1:10 year storm event level was dealt
with by means of a piped conveyance system. This system
included all required catchbains, catchbasin manholes,
manholes and storm sewer piping necessary to tie into an
existing storm sewer trunk. The 11 m depth of the trunk
required design of a drop manhole and energy dissipater in
order to limit sewer drainage caused by high velocity flows.
A flow control orifice was incorporated into the piped system
to accommodate limited capacity in the receiving stormwater
trunk.
The project currently in the final design stage.

1. GUYANA, SOUTH AMERICA
WATER PUMPING STATIONS/FACILITIES REHABILITATION
Maxim Engineering Inc. was commissioned by Guyana Water
Authority (GUYWA) to prepare preliminary rehabilitation
designs for thirty-five (35) water pumping stations/facilities
and detailed designs including preparation of bidding
documents for ten (10) pumping stations/facilities as part of
the World Bank funded Water Supply Technical Assistance and
Rehabilitation Project. The programme objective with respect
to pumping stations/facilities is rehabilitation of existing
systems that have fallen into various states of disrepair over
a number of years as a direct result of insufficient
maintenance.
During the initial conditions inspections in late March, 1993,
it became apparent that a number of the 35 stations that had
been selected by GUYWA for pre-design were interconnected to
adjacent pumping stations/facilities. The extent of the
interconnections was confirmed in June when it was determined
that the original list of 35 stations impacted on a total of
86 facilities.
The presence of extensive interconnected systems meant that
the World Bank's original programme strategy to rehabilitate
individual pumping stations/facilities was no longer cost
effective. Maxim Engineering Inc. developed a new approach
focusing on rehabilitation of interconnected systems with an
emphasis on reducing the overall number of pumping stations
and associated operating and maintenance costs.
Maxim finalized the pre-design reports for 7 major water
supply/treatment rehabilitation schemes (including complete
distribution system reconstruction) servicing a total
population of 160,000. We subsequently finalized detailed
rehabilitation designs and bidding documents for 6 water
treatment plants, 4 elevated storage towers, 27 water pumping
stations and associated interconnecting transmission mains for
the 7 systems.
In addition, Maxim was commissioned to conduct a site
evaluation of the existing Water Treatment Plant at Bartica
on the west bank of the Essiquibo River. We were then
authorized to prepare a pre-design study, tender documents and
specifications for complete rehabilitation of the water
treatment plant.

2. TOWN OF MILLET
WATER SUPPLY AND DISTRIBUTION STUDY
The Town of Millet, with a population of 2,000, uses a
water distribution network supplied by a central reservoir
which in turn is supplied by ground water wells. A barely
sufficient water supply capacity and low system pressures
warranted an overall Water Supply and Distribution Study.
Data was collected and reviewed to assess the existing water
supply capacity. Future Town populations were then projected
to identify future water supply needs. The distribution
system was modelled utilizing the "WATER" computer program
and later calibrated using flow and system pressure data
collected in the field. The calibrated model was used to
identify system modifications required to boost system
pressures now and in the future and to stimulate future
expansion of the distribution system. Recommendations for
phased construction of system and supply modifications were
submitted in report form.
Subsequent to submission of our report, the Town commissioned
Maxim to retain a groundwater hydrologist to identify and
complete a suitable additional well water supply and
authorized Maxim to connect the wells to the existing
reservoir. The new walls also generated upgrading of water
treatment plant controls and the installation of a new
distribution pump. Maxim provided design plans and
specifications, received construction tenders, reviewed and
recommended for contract award and provided construction
inspection and contract administration.
Client: Town of Millet, Alberta
Year: 1995
3. RESERVOIR REHABILITATION
TOWN OF EDSON
Maxim carried out site investigation work and prepared a
detailed feasibility study report for upgrading the five
potable water reservoirs for the Town of Edson. These
reservoirs structures included an elevated steel tower
and tank (100 ft - 50,000 imperial gallon capacity), two
underground concrete tanks, one above ground concrete
tank (75 ft diameter x 30 ft high), and one above ground steel
tank (60 ft diameter x 30 ft high). Only minor upgrading was
recommended for the concrete structures. The steel reservoirs
however were in need or significant rehabilitation.
Following acceptance of our recommendations, Maxim was
commissioned to prepare the necessary design, to tender the
project, and to provide construction inspection and project
management services. Remedial work included installation of
new foundation systems, sandblasting of steel, installation of
new fibreglass and epoxy liners, and new insulation for
exterior surfaces.

4. CAMP WAINWRIGHT
WATER PRODUCTION SYSTEM AUTOMATION STUDY
Maxim was commissioned to study the potable water production
facilities located on Camp Wainwright to determine how to
automate the system to enable production hours to be expanded
from 12 to 24 hours while reducing required operating hours
from 12 to eight.
The existing system includes a river intake pumping station
which pumps raw water to a large raw water storage reservoir
(lake). A conventional 1.5 MGD water treatment plant treats
raw water from the lake using clarification and filtration,
and then pumps the potable water to an underground storage
reservoir. Booster pumps deliver the water, through metering
stations which monitor the flows, from the underground storage
to elevated storage reservoirs at the Town of Wainwright and
at Camp Central.
The water treatment plant has a programmable logic controller
(PLC) in which the automatic mode has not reliably operated
since installation. A telemetry system uses several terminal
units (RTU's) to link all the facilities to the water
treatment plant, except for the river pumping station which
is independently operated. The RTU's do not operate
reliably.
Maxim personnel visited the site several times to collect
data, receive input from system operating personnel and
camp engineers, and share ideas. As a result, Maxim personnel
gained a comprehensive understanding of the system and the
client's goals. From this, a simply clear report was written
which identified the required changes to the existing control
and telemetry system, and to areas of the process in order to
automate the plant.
Changes to the control system included upgrading and
re-programming the PLC to provide automatic operation,
installing a user friendly computerized Man Machine Interface
(MMI) to assist operators to control, track and manage the
system, installing new reliable RTU's to relay information
from all the remote facilities over existing telephone lines
to the PLC and the MMI. Changes to the process included
installing new pumps, valves, and instrumentation to support
24 hour operation.
The report was implemented and the construction is now
complete.

1. SEWAGE TREATMENT PLANT EXPANSION - WAINWRIGHT, ALBERTA
Maxim Engineering provided pre-design and detailed engineering
services for Wainwright's sewage treatment lagoon expansion.
The project was constructed during the summer of 1993. The
lagoon expansion included construction of a new aerated
complete mix cell, replacement of the aeration system in the
existing facultative cells, new blower/motor installation and
new manhole/control structures including all associated piping
and sewers.
A total of 145 static tube aerators were installed to provide
mixing and oxygen entertainment in the complete mix cell. A
synthetic liner prevents contamination of groundwater in the
predominantly silty/sandy soil. An additional 192 new static
tube aerators provide aeration for the two existing
facultative cells. Air for all static tubes is provided by
five 40 Hp blowers with one acting as standby. The air
provided to operate the whole facility totals 3800 cubic feet
per minute (1800 litres per second).
Maxim also acted as liaison between the Town and various
permitting agencies in obtaining the required approvals
for construction.

2. ORGANIZATION OF EASTERN CARIBBEAN STATES
SEWERAGE AND SEWAGE TREATMENT STUDY
Maxim Engineering Inc. was contracted by the World Bank and
the Organization of Eastern Caribbean States (OECS) to
complete pre-feasibility study of proposed and potential
sewerage and sewage treatment projects in the OECS countries
of St. Kitts & Nevis, Antigua & Barbuda, Dominica, St. Lucia,
St. Vincent & the Grenadines and Grenada. The objective was
to identify priority projects in each of the countries and to
develop a framework by which international lending agencies
could assess the feasibility of financing these projects. The
final report would also outline what each country has to do in
order to implement particular projects.
The project scope includes the following aspects:
- Technical Aspects - determination of appropriate
technologies for collection, treatment and disposal
of sewage. This included preliminary layout of collection
systems, comparison of treatment methods, and determination
of appropriate disposal options including land based
solutions and submarine ocean outfalls. The investigation
included an assessment required for each project and a
cost/benefit analysis of the alternative presented.
- Institutional/Legislative - in order to properly implement
the proposed technical solutions, each country's capacity to
operate, maintain and regulate sewage facilities was
evaluated. This included an analysis of designated
management and technical personnel in the National Water and
Sewage Authority, organization structure, management
information systems, current cost recovery measures,
applicable legislation and regulations, linkages with
regulatory and planning authorities etc.
- Socio/Economic - included in the implementation strategy
for identified priority projects is the people's ability
and willingness to pay. In the context of developing
countries, household income and preferences govern whether
a community wants and can afford to implement any type of
a sewage system.
The project commenced in January, 1996 and the final report
was submitted in December, 1996.

3. CLOVER BAR SLUDGE LAGOONS & SUPERNATANT PIPELINE
GOLD BAR WASTEWATER TREATMENT PLANT - EDMONTON
In 1995, Maxim Engineering Inc. was commissioned by the City
of Edmonton to upgrade solids and liquids handling
capability/capacity at the City's Clover Bar Sludge Lagoons.
The project scope of work included:
- upgrading of the lagoon underground decant/conveyance
system;
- a floating lagoon pumper, and a cutter suction dredge;
- an internal/external integrity investigation on the existing
8 inch diameter steel pipelines between Clover Bar Lagoons
and the Gold Bar Wastewater Treatment Plant, and;
- pre-design, design and construction of a new 5 kilometre
long, 300 mm diameter, supernatant/sludge pipeline including
a full environmental impact assessment (EIA).
The decanting system improvements have been implemented, the
sludge pumping equipment has been purchased and
commissioned, the existing pipelines have been externally
investigated and one section has had the internal investigation
completed, and the pre-design and EIA for the new pipeline have
been completed.
Since the project commenced in 1995, the TransAlta (T.E.N.)
Composting Facility has been approved by City Council and a new
wastewater disposal pipeline for Celanese Canada Inc. has been
included into the project. The composting facility impacted
significantly on the pipeline portion of the City project because
sludge from Gold Bar and Clover Bar Lagoons (CBL) must now be
delivered to the T.E.N. site rather than from Gold Bar to CBL.
Since the composting facility was approved, Maxim has worked
closely with TransAlta staff to facilitate transporting sludge
and filtrate to and from the T.E.N. site and to meet the
operation requirements of T.E.N. and the City.
The new wastewater disposal pipeline for Celanese was included
into the project because of its similar technical requirements to
the new sludge/supernatant pipeline, the concurrent timing and
the mutual economic benefits to the City and Celanese. Inclusion
of this second new pipeline has doubled the estimated total
project cost from $2.5 million to $5 million. The project was
designed, tendered and construction management provided by Maxim.

regional evaporation lagoon for the Summer Villages of Sandy
Beach and Sunrise.
The communities are situated on the shores of Sandy Lake, 35
km west of Morinville, and the implementation of a regional
lagoon had to be undertaken so that it would not have a
negative environmental impact on either Sandy Lake or Baird
Lake, located on Alexander Indian Band property to the east.
The project included determination of design flows based upon
available records, site selection, geotechnical evaluation
and design for a compacted-clay lined evaporation pond with
controlled access dumping.

Typically projects have included:
1. TOLKO INDUSTRIES LTD.
HIGH PRAIRIE OSB MILL
LOG YARD AND GANTRY CRANE TRACKAGE
Tolko Industries Ltd. of Vernon, British Columbia was
awarded the timber rights for the High Prairie Timber
Development Area. As a result, Tolko has built a 450 million
square foot (3/8" basis) Oriented Strand Board (OSB) Mill at
High Prairie, Alberta.
To handle the raw logs in the wood yard it was decided to
install a portal gantry crane which has a 205 foot span,
85 foot cantilevers and lifts 30 tons. The supply of the
crane, log yard development and crane trackage was awarded to
Kone Wood. Morrison Hershfield Limited sub-contracted by
Kone Wood to engineer, design & construct the log yard and crane
trackage.
Detail engineering was carried out with the results that the
project's final configuration involved moving 120,000 Cu.Yd.
of gravel placement, 6,000 lin. feet of sub-drains, drainage
ditches, culverts, lift stations, 500 feet of reinforced earth
retaining wall, 1,500 feet of gantry crane trackage, concrete
pavement and safety barriers, and miscellaneous structures.
A project of this nature required the involvement of a
multi-discipline engineering and contracting approach and the
team that Morrison Hershfield Limited assembled involved a
full range of heavy civil engineering and construction firms.
After three years of operations, a forest fire Northwest of the
Tolko High Prairie OSB Mill spread to the log yard destroying
the log inventory and the gantry crane. Morrison Hershfield
Limited was then commissioned immediately to provide cost
estimates and plans for replacing the crane.
Once the immediate needs had been met, the destruction of the
log handling equipment afforded Tolko with the opportunity to
reassess the use of a gantry crane vs conventional mobile
equipment. Working very closely with Tolko personnel, Morrison
Hershfield Limited carried out a study on available log handling
systems. The written report, which resulted from the study, was
presented to the Owners of Tolko who then made the final
decision on the log handling system.
2. ZEIDLER FOREST INDUSTRIES LTD.
LOG YARD DEVELOPMENT
Morrison Hershfield Limited has been commissioned by Zeidler
to carry out a study on the log handling systems available and to
determine which system would be best for Zeidler's Slave Lake
Veneer Mill and Sawmill.
In addition to the log yard, also included in the review was
the use and upgrading of the lumber yards, peeler handing
area, plant roads and travelling area. Alternative yard
layouts were developed, cost estimates prepared, advantages
and disadvantages reported.
3. VANDERWELL'S MITSUE SAWMILL
SITE DEVELOPMENT
PHASE 1 - LOG YARD AND GANTRY CRANE TRACKAGE
For a number of years the operation at Vanderwell's Mitsue
Sawmill has been hindered by very poor site conditions for
storing and moving logs to the sawmill. This resulted in
Vanderwell ordering a gantry crane for the handling of logs.
Vanderwell then commissioned Morrison Hershfield to review
alternatives and prepare a conceptual design for the gantry
crane trackage, overall log yard and general site
improvements. Once these alternatives were presented and
Vanderwell chose the best alternatives for their position,
Morrison Hershfield Limited then proceeded with the detailed
design, assisted with ordering materials, and managed the
construction of the facilities.
PHASE 2 - LUMBER YARD PAVEMENT
During the winter of 1998, a gravel source was obtained and a
crushing contract let to prepare 150,000 tonnes of aggregate
for the paving of the lumber handling areas of the sawmill
site. During June and July, the earthworks were carried out
preparing the site for roller compacted concrete surfacing
of the lumber handling area.
The roller compacted contract has been awarded and 82,000 m
sq. of roller compacted concrete will be placed in August,
1998.
This will complete the re-development of the sawmill site

In 1998-99 Morrison Hershfield provided design engineering for
the approval and construction of a major stormwater drainage
system which services the centre and business section of town.
The existing system was undersized and causing frequent flooding
during the summer months.
The new system, with a total length of 3000m, was comprised of
three elements: pipe, ditching and two stormwater detention
ponds. Because of limited clearances with existing utilities,
round and arch CMP pipe was used, ranging in size from 750 mm to
1790 X 1360 arch.
Currently, MH is carrying out a complete water network analysis
having done a sanitary sewer system and stormwater drainage
analysis over the last few years. Also at the present time, MH
is designing two new subdivisions and an extension of servicing
for a new institutional facility site.
2. ORGANIZATION OF EASTERN CARIBBEAN STATES
SEWERAGE AND SEWAGE TREATMENT STUDY
Morrison Hershfield Limited was contracted by the World Bank and
the Organization of Eastern Caribbean States (OECS) to
complete a pre-feasibility study of proposed and potential
sewerage and sewage treatment projects in the OECS countries
of St. Kitts & Nevis, Antigua & Barbuda, Dominica, St. Lucia,
St. Vincent & the Grenadines and Grenada. The objective was
to identify priority projects in each of the countries and to
develop a framework by which international lending agencies
can assess the feasibility of financing these projects. The
final report included an outline of what each country has to
do in order to implement particular projects.
The project scope included the following aspects:
- Technical Aspects - determination of appropriate
technologies for collection, treatment and disposal
of sewage. This includes preliminary layout of collection
systems, comparison of treatment methods, and determination
of appropriate disposal options including land based
solutions and submarine ocean outfalls. The investigation
included an assessment required for each project and a
cost/benefit analysis of the alternative presented.
- Institutional/Legislative - in order to properly implement
the proposed technical solutions, each country's capacity
to operate, maintain and regulate sewage facilities was
evaluated. This included an analysis of designated
management and technical personnel in the National Water and
Sewage Authority, organization structure, management
information systems, current cost recovery measures,
applicable legislation and regulations, linkages with
regulatory and planning authorities etc.
- Socio/Economic - included in the implementation strategy for
identified priority projects is the people's ability and
willingness to pay. In the context of developing countries,
household income and preferences govern whether a community
wants and can afford to implement any type of a sewage
system.
The project commenced in January, 1996 and the final report
was submitted in December 1996.
Client: World Bank/Organization of Eastern Caribbean States

2. CLOVER BAR SLUDGE LAGOONS & SUPERNATANT PIPELINE
GOLD BAR WASTEWATER TREATMENT PLANT - EDMONTON
Morrison Hershfield Limited was commissioned by the City
of Edmonton to upgrade solids and liquids handling
capability/capacity at the City's Clover Bar Sludge Lagoons.
The project scope of work included:
- upgrading of the lagoon underground decant/conveyance
system;
- a floating lagoon pumper, and a cutter suction dredge;
- an internal/external integrity investigation on the existing
8 inch diameter steel pipelines between Clover Bar Lagoons
and the Gold Bar Wastewater Treatment Plant, and;
- pre-design, design and construction of a new 5 kilometre
long, 300 mm diameter, supernatant/sludge pipeline including
a full environmental impact assessment (EIA).
Since the project commenced in 1995, the TransAlta (T.E.N.)
Composting Facility has been approved by City Council and a new
wastewater disposal pipeline for Celanese Canada Inc. has been
included into the project. The composting facility impacted
significantly on the pipeline portion of the City project
because sludge from Gold Bar and Clover Bar Lagoons (CBL), must
now be delivered to the T.E.N. site rather than from Gold Bar to
CBL.
Since the composting facility was approved, Morrison Hershfield
has worked closely with TransAlta staff to facilitate
transporting sludge and filtrate to and from the T.E.N. site and
to meet the operation requirements of T.E.N. and the City.
The new wastewater disposal pipeline for Celanese was included
into the project because of its similar technical requirements
to the new sludge/supernatant pipeline, the concurrent timing
and the mutual economic benefits to the City of Celanese.
Inclusion of this second new pipeline doubled the total project
cost from $2.5 million to $5 million. The project is now
complete.

1. GUYANA, SOUTH AMERICA
WATER PUMPING STATIONS/FACILITIES REHABILITATION
Maxim Engineering Inc. was commissioned by Guyana Water
Authority (GUYWA) to prepare preliminary rehabilitation
designs for thirty-five (35) water pumping stations/facilities
and detailed designs including preparation of bidding
documents for ten (10) pumping stations/facilities as part of
the World Bank funded Water Supply Technical Assistance and
Rehabilitation Project. The programme objective with respect
to pumping stations/facilities is rehabilitation of exisiting
systems that have fallen into various states of disrepair over
a number of years as a direct result of insufficient
maintenance.
During the initial conditions inspections in late March, 1993,
it became apparent that a number of the 35 stations that had
been selected by GUYWA for pre-design were interconnected to
adjacent pumping stations/facilities. The extent of the
interconnections was confirmed in June when it was determined
that the original list of 35 stations impacted on a total of
86 facilities.
The presence of extensive interconnected systems meant that
the World Bank's original programme strategy to rehabilitate
individual pumping stations/facilities was no longer cost
effective. Maxim Engineering Inc. developed a new approach
focusing on rehabilitation of interconnected systems with an
emphasis on reducing the overall number of pumping stations
and associated operating and maintenance costs.
Maxim finalized the pre-design reports for 7 major water
supply/treatment rehabilitation schemes (including complete
distribution system reconstruction) servicing a total
population of 160,000. We subsequently finalized detailed
rehabilitation designs and bidding documents for 6 water
treatment plants, 4 elevated storage towers, 27 water pumping
stations and associated interconnecting transmission mains for
the 7 systems.
In addition, Maxim was commissioned to conduct a site
evaluation of the existing Water Treatment Plant at Bartica
on the west bank of the Essiquibo River. We were then
authorized to prepare a pre-design study, tender documents and
specifications for complete rehabilitation of the water
treatment plant.
Client: Guyana Water Authority
Year: 1993 - 1996
Cost: $15,600,000
2. TOWN OF MILLET
WATER SUPPLY AND DISTRIBUTION STUDY
The Town of Millet, with a population of 2,000, uses a
water distribution network supplied by a central reservoir
which in turn is supplied by ground water wells. A barely
sufficient water supply capacity and low system pressures
warranted an overall Water Supply and Distribution Study.
Data was collected and reviewed to assess the existing water
supply capacity. Future Town populations were then projected
to identify future water supply needs. The distribution
system was modelled utilizing the "WATER" computer program
and later calibrated using flow and system pressure data
collected in the field. The calibrated model was used to
identify system modifications required to boost system
pressures now and in the future and to simulate future
expansion of the distribution system. Recommendations for
phased construction of system and supply modifications were
submitted in report form.
Subsequent to submission of our report, the Town commissioned
Maxim to retain a groundwater hydrologist to identify and
complete a suitable additional well water supply and
authorized Maxim to connect the wells to the existing
reservoir. The new wells also generated upgrading of water
treatment plant controls and the installation of a new
distribution pump. Maxim provided design plans and
specifications, received construction tenders, reviewed and
recommended for contract award and provided construction
inspection and contract administration.
Client: Town of Millet, Alberta
Year: 1995
3. RESERVOIR REHABILITATION
TOWN OF EDSON
Maxim carried out site investigation work and prepared a
detailed feasibility study for upgrading the five potable
water reservoirs for the Town of Edson. These reservoir
structures included an elevated steel tower and tank
(100 ft - 50,000 imperial gallon capacity), two underground
concrete tanks, one above ground concrete tank
(75 ft diameter x 30 ft high), and one above ground steel
tank (60 ft diameter x 30 ft high). Only minor upgrading was
recommended for the concrete structures. The steel reservoirs
however were in need of significant rehabilitation.
Following acceptance of our recommendations, Maxim was
commissioned to prepare the necessary design, to tender the
project, and to provide construction inspection and project
management services. Remedial work included installation of
new foundation systems, sandblasting of steel, installation of
new fibreglass and epoxy liners, and new insulation for
exterior surfaces.
Client: Town of Edson
Year: 1990
Cost: $100,000
4. CAMP WAINWRIGHT (DEPARTMENT OF NATIONAL DEFENCE)
WATER PRODUCTION SYSTEM AUTOMATION STUDY
Maxim was commissioned to study the potable water production
facilities located on Camp Wainwright to determine how to
automate the system to enable production hours to be expanded
from 12 to 24 hours while reducing required operating hours
from 12 to eight.
The existing system includes a river intake pumping station
which pumps raw water to a large raw water storage reservoir
(lake). A conventional 1.5 MGD water treatment plant treats
raw water from the lake using clarification and filtration,
and then pumps the potable water to an underground storage
reservoir. Booster pumps deliver the water, through metering
stations which monitor the flows, from the underground storage
to elevated storage reservoirs at the Town of Wainwright and
at Camp Central.
The water treatment plant has a programmable logic controller
(PLC) in which the automatic mode has not reliably operated
since installation. A telemetry system uses several terminal
units (RTU's) to link all the facilities to the water
treatment plant, except for the river pumping station which
is independently operated. The RTU's do not operate
reliably.
Maxim personnel visited the site several times to collect
data, receive input from system operating personnel and
camp engineers, and share ideas. As a result, Maxim personnel
gained a comprehensive understanding of the system and the
client's goals. From this, a simple clear report was written
which identified the required changes to the existing control
and telemetry system, and to areas of the process in order to
automate the plant.
Changes to the control system included upgrading and
re-programming the PLC to provide automatic operation,
installing a user friendly computerized Man Machine Interface
(MMI) to assist operators to control, track and manage the
system, installing new reliable RTU's to relay information
from all the remote facilities over existing telephone lines
to the PLC and the MMI. Changes to the process included
installing new pumps, valves, and instrumentation to support
24 hour operation.
The report was well received and implementation of the
recommendations was completed with Maxim providing general
engineering services during construction.

2. ORGANIZATION OF EASTERN CARIBBEAN STATES
SEWERAGE AND SEWAGE TREATMENT STUDY
Maxim Engineering Inc. was contracted by the World Bank and
the Organization of Eastern Caribbean States (OECS) to
complete a pre-feasibility study of proposed and potential
sewerage and sewage treatment projects in the OECS countries
of St. Kitts & Nevis, Antigua & Barbuda, Dominica, St. Lucia,
St. Vincent & the Grenadines and Grenada. The objective was
to identify priority projects in each of the countries and to
develop a framework by which international lending agencies
can assess the feasibility of financing these projects. The
final report included an outline of what each country has to
do in order to implement particular projects.
The project scope included the following aspects:
- Technical Aspects - determination of appropriate
technologies for collection, treatment and disposal
of sewage. This includes preliminary layout of collection
systems, comparison of treatment methods, and determination
of appropriate disposal options including land based
solutions and submarine ocean outfalls. The investigation
included an assessment required for each project and a
cost/benefit analysis of the alternative presented.
- Institutional/Legislative - in order to properly implement
the proposed technical solutions, each country's capacity to
operate, maintain and regulate sewage facilities was
evaluated. This included an analysis of designated
management and technical personnel in the National Water
and Sewage Authority, organization structure, management
information systems, current cost recovery measures,
applicable legislation and regulations, linkages with
regulatory and planning authorities etc.
- Socio/Economic - included in the implementation strategy
for identified priority projects is the people's ability
and willingness to pay. In the context of developing
countries, household income and preferences govern whether
a community wants and can afford to implement any type of
a sewage system.
The project commenced in January, 1996 and the final report
was submitted in December, 1996.

3. CLOVER BAR SLUDGE LAGOONS & SUPERNATANT PIPELINE
GOLD BAR WASTEWATER TREATMENT PLANT - EDMONTON
In 1995, Maxim Engineering Inc. was commissioned by the City
of Edmonton to upgrade solids and liquids handling
capability/capacity at the City's Clover Bar Sludge Lagoons.
The project scope of work included:
- upgrading of the lagoon underground decant/conveyance
systsem;
- a floating lagoon pumper, and a cutter suction dredge;
- an internal/external integrity investigation on the existing
8 inch diameter steel pipelines between Clover Bar Lagoons
and the Gold Bar Wastewater Treatment Plant, and;
- pre-design, design and construction of a new 5 kilometre
long, 300 mm diameter, supernatant/sludge pipeline including
a full environmental impact assessment (EIA).
Since the project commenced in 1995, the TransAlta (T.E.N.)
Composting Facility has been approved by City Council and a new
wastewater disposal pipeline for Celanese Canada Inc. has been
included into the project. The composting facility impacted
significantly on the pipeline portion of the City project because
sludge from Gold Bar and Clover Bar Lagoons (CBL) must now be
delivered to the T.E.N. site rather than from Gold Bar to CBL.
Since the composting facility was approved, Maxim has worked
closely with TransAlta staff to facilitate transporting sludge
and filtrate to and from the T.E.N. site and to meet the
operation requirements of T.E.N. and the City.
The new wastewater disposal pipeline for Celanese was included
into the project because of its similar technical requirements to
the new sludge/supernatant pipeline, the concurrent timing and
the mutual ecomomic benefits to the City and Celanese. Inclusion
of this second new pipeline doubled the total project cost from
$2.5 million to $5 million. The project is now completed.

Typical projects are as follows:
1. BYRAM INDUSTRIAL SERVICES LTD. - PEMBINA AREA LANDFILL
The most efficient and cost effective, yet environmentally sound
manner of disposal of oilfield/industrial waste is to develop a
Class 1a Industrial landfill.
During the spring and summer of 1996 Byram Industrial Services
Ltd. (BISL) identified several possible sites and through a
preliminary screening of geological characteristics identified a
good site for a Class 1a Hazardous Waste Industrial Landfill.
After preliminary discussions with Alberta Environment (AEVN)
and public meetings with local residents, a Project Disclosure
Document was published and distributed to the general public,
interested third parties and AEVN. Under the Alberta
Environmental Protection Act a Class 1a landfill is a mandatory
activity that requires a full Environmental Impact Assessment
(EIA) be carried out. This EIA was carried out and submitted to
AEVN in December 1997.
Once the EIA was accepted as complete, the Application to
Construct, Operate and Reclaim the landfill was prepared and
submitted in July 1998.
Throughout this process a Coalition of Environmental groups
monitored the complete process and in October 1998 a specially
prepared document addressing their specific concerns was
prepared and submitted to these special interest groups.
The approval for the construction of the landfill was obtained
from AEVN on April 21, 1999 and construction of the facilities
started in early May. The construction took 5 months and the
landfill went into operation in early September 1999. The
landfill consists of the following facilities on 300 hectares of
land:
Þ Access road
Þ Scales, office and laboratory
Þ Run-on and runoff drainage control
Þ Monitoring wells, terrestrial sample plots, aquatic life
sampling plots and monitoring facilities.
Þ A 100 metre by 100 metre first disposal cell
Þ The necessary support facilities
The site has been conceptually approved for 32 similar sized
cells and it is anticipated that it will have a life of twenty-
five to thirty years.

included construction of a new aerated complete mix cell,
replacement of the aeration system in the existing cells and
installation of a new blower/motor and new manhole/control
structures associated with piping and sewers. Construction of
this project was completed during the summer of 1993.
In addition to these civil engineering assignments, Morrison
Hershfield has provided building engineering services, including
electrical, instrumentation and mechanical engineering for a
retrofit of the firehall. Mechanical, electrical and
instrumentation engineering services were also provided for
upgrading of the control and telemetry system for the Wainwright
Regional Water Treatment Plant, which is located at the Canadian
Forces Base Wainwright.
In 1998-99 Morrison Hershfield provided design engineering for
the approval and construction of a major stormwater drainage
system which services the centre and business section of town.
The existing system was undersized and causing frequent flooding
during the summer months.
The new system, with a total length of 3000m, was comprised of
three elements: pipe, ditching and two stormwater detention
ponds. Because of limited clearances with existing utilities,
round and arch CMP pipe was used, ranging in size from 750 mm to
1790 X 1360 arch.
Currently, MH is carrying out a complete water network analysis
having done a sanitary sewer system and stormwater drainage
analysis over the last few years. Also at the present time, MH
is designing two new subdivisions and an extension of servicing
for a new institutional facility site.
3. ORGANIZATION OF EASTERN CARIBBEAN STATES
SEWERAGE AND SEWAGE TREATMENT STUDY

complete a pre-feasibility study of proposed and potential
sewerage and sewage treatment projects in the OECS countries
of St. Kitts & Nevis, Antigua & Barbuda, Dominica, St. Lucia,
St. Vincent & the Grenadines and Grenada. The objective was
to identify priority projects in each of the countries and to
develop a framework by which international lending agencies
can assess the feasibility of financing these projects. The
final report outlined what each country has to do in order to
implement particular projects.
The project scope included the following aspects:
- Technical Aspects - determination of appropriate
technologies for collection, treatment and disposal of
sewage. This includes preliminary layout of collection
systems, comparison of treatment methods, and determination
of appropriate disposal options including land based
solutions and submarine ocean outfalls. The investigation
included an assessment required for each project and a
cost/benefit analysis of the alternative presented.
- Institutional/Legislative - in order to properly implement
the proposed technical solutions, each country's capacity
to
operate, maintain and regulate sewage facilities was
evaluated. This included an analysis of designated
management and technical personnel in the National Water and
Sewage Authority, organization structure, management
information systems, current cost recovery measures,
applicable legislation and regulations, linkage with
regulatory and planning authorities etc.
- Socio/Economic - included in the implementation strategy
for identified priority projects is the people's ability
and willingness to pay. In the context of developing
countries, household income and preference govern whether a
community wants and can afford to implement any type of a
sewage system.
The project commenced in January, 1996 and the final report
was submitted in December, 1996.
Client: World Bank/Organization of Eastern Caribbean States
4. CLOVER BAR SLUDGE LAGOONS & SUPERNATANT PIPELINE
GOLD BAR WASTEWATER TREATMENT PLANT - EDMONTON
The project involved the upgrading of the sewage sludge and
liquid effluent handling system. During 1996, the liquid
decanting system improvements were implemented, the sludge
pumping equipment was purchased and commissioned, the existing
pipelines were externally investigated and one section had the
internal investigation completed. The pre-design, design, EIA
and construction of 5 km of new pipeline were completed in 1997.
Subsequent to having been awarded the project, the TransAlta Co-
Composter Facility was approved by City Council. In addition,
Celanese Canada requested a tie-in to the City sewage system.
These two events added substantially to the project by adding a
second crossing of the river with an outfall from Celanese and
changing the piping and valving so that sludge and filtrate
could be delivered to the Co-Composter. Also designed and
constructed was the piping and valving to enable the City to
reclaim sludge and filtrate from the lagoons and deliver it to
the Co-Composter. Morrison Hershfield staff worked closely with
Celanese and TransAlta personnel as well as the client, the City
of Edmonton, to successfully design, construct and commission
the reclaim system, pipeline and transfer valving.
The new 250mm Dia. HDPE wastewater disposal pipeline for
Celanese was included into the project because of the similar
technical requirements to the new sludge/supernatant pipeline,
the concurrent timing and the mutual economic benefits to the
City and Celanese.
The installation of the pipelines was completed in 1997, with
the Saskatchewan River crossing accomplished by the directional
drilling method for both the steel and HDPE lines. Morrison
Hershfield provided the design, contract drawings and
specifications, project management and construction engineering
services for the total project.

4. CLOVER BAR SLUDGE LAGOONS & SUPERNATANT PIPELINE
GOLD BAR WASTEWATER TREATMENT PLANT - EDMONTON
In 1995, Maxim Engineering Inc. was commissioned by the City
of Edmonton to upgrade solids and liquids handling
capability/capacity at the City's Clover Bar Sludge Lagoons.
The project scope of work included:
- upgrading of the lagoon underground decant/conveyance
systems;
- a floating lagoon pumper, and a cutter suction dredge;
- an internal/external integrity investigation on the existing
8 inch diameter steel pipelines between Clover Bar Lagoons
and the Gold Bar Wastewater Treatment Plant, and;
- pre-design, design and construction of a new 5 kilometre
long, 300 mm diameter, supernatant/sludge pipeline including
a full environmental impact assessment (EIA).
At present, the decanting system improvements have been partially
implemented, the sludge pumping equipment has been purchased and
commissioned, the existing pipelines have been externally
investigated and one section has had the internal investigation
completed, and pre-design and EIA for the new pipeline was
completed.
Since the project commenced in 1995, the TransAlta (T.E.N.)
composting facility was approved by City Council and a new
wastewater disposal pipeline for Celanese Canada Inc. was
included in the project. The composting facility impacted
significantly on the pipeline portion of the City project because
sludge from Gold Bar and Clover Bar Lagoons (CBL) must now be
delivered to the T.E.N. site rather than from Gold Bar to CBL.
Since the composting facility was approved, Maxim has worked
closely with TransAlta staff to facilities transporting sludge
and filtrate to and from the T.E.N. site and to meet the
operation requirements of T.E.N. and the City.
The new wastewater disposal pipeline for Celanese was included
into the project because of its similar technical requirements to
the new sludge/supernatant pipeline, the concurrent timing and
the mutual economic benefits to the City and Celanese. Inclusion
of this second new pipeline has doubled the estimated total
project cost from $2.5 million to $5 million.

3. ORGANIZATION OF EASTERN CARIBBEAN STATES
SEWERAGE AND SEWAGE TREATMENT STUDY
Maxim Engineering Inc. was contracted by the World Bank and
the Organization of Eastern Caribbean States (OECS) to
complete a pre-feasibility study of proposed and potential
sewerage and sewage treatment projects in the OECS countries
of St. Kitts & Nevis, Antigua & Barbuda, Dominica, St. Lucia,
St. Vincent & Grenadines and Grenada. The objective was to
identify priority projects in each of the countries and to
develop a framework by which international lending agencies
can assess the feasibility of financing these projects. The
final report outlined what each country has to do in order to
implement particular projects.
The project scope included the following aspects:
- Technical Aspects - determination of appropriate
technologies for collection, treatment and disposal of
sewage. This includes preliminary layout of collection
systems, comparison of treatment methods, and determination
of appropriate disposal options including land based
solutions and submarine ocean outfalls. The investigation
included an assessment required for each project and a
cost/benefit analysis of the alternative presented.
- Institutional/Legislative - in order to properly implement
the proposed technical solutions, each country's capacity to
operate, maintain and regulate sewage facilities was
evaluated. This included an analysis of designated
management and technical personnel in the National Water and
Sewage Authority, organization structure, management
information systems, current cost recovery measures,
applicable legislation and regulations, linkages with
regulatory and planning authorities etc.
- Socio/Economic - included in the implementation strategy for
identified priority projects is the people's ability and
willingness to pay. In the context of developing countries,
household income and preference govern whether a community
wants and can afford to implement any type of a sewage
system.
The project commenced in January, 1996 and the final report
was submitted in December, 1996.
Client: World Bank/Organization of Eastern Caribbean States
Study Cost: $450,000 CDN

4. CLOVER BAR SLUDGE LAGOONS & SUPERNATANT PIPELINE
GOLD BAR WASTEWATER TREATMENT PLANT - EDMONTON
In 1995, Maxim Engineering Inc. was commissioned by the City
of Edmonton to upgrade solids and liquids handling
capability/capacity at the City's Clover Bar Sludge Lagoons.
The project scope of work included:
- upgrading of the lagoon underground decant/conveyance
systems;
- a floating lagoon pumper, and a cutter suction dredge;
- an internal/external integrity investigation on the existing
8 inch diameter
- pre-design, design and construction of a new 5 kilometre
long, 300 mm diameter, supernatant/sludge pipeline including
a full environmental impact assessment (EIA).
At present, the decanting system improvements have been partially
implemented, the sludge pumping equipment has been purchased and
commissioned, the existing pipelines have been externally
investigated and one section has had the internal investigation
completed, and the pre-design and EIA for the new pipeline was
completed.
Since the project commenced in 1995, the TransAlta (T.E.N.)
Composting Facility was approved by City Council and a new
wastewater disposal pipeline for Celanese Canada Inc. was
included in the project. The composting facility was approved,
Maxim has worked closely with TransAlta staff to facilitate
transporting sludge and filtrate to and from the T.E.N. site and
to meet the operation requirements of T.E.N. and the City.
The new wastewater disposal pipeline for Celanese was included
into the project because of its similar technical requirements to
the new sludge/supernatant pipeline, the concurrent timing and
the mutual economic benefits to the City and Celanese. Inclusion
of this second new pipeline has doubled the estimated total
project cost from $2.5 million to $5 million.

composting facility was approved by City Council and a new
wastewater disposal pipeline for Celanese Canada Inc. was
included in the project. The composting facility impacted
significantly on the pipeline portion of the City project because
sludge from Gold Bar and Clover Bar Lagoons (CBL) must now be
delivered to the T.E.N. site rather than from Gold Bar to CBL.
Since the composting facility was approved, Maxim has worked
closely with TransAlta staff to facilities transporting sludge
and filtrate to and from the T.E.N. site and to meet the
operation requirements of T.E.N. and the City.
The new wastewater disposal pipeline for Celanese was included
