1.0 BACKGROUND
1.1 In January 2003 the Region of Durham informed Clarington that they would be
undertaking a Class Environmental Assessment for the provision of additional water
supply capacity for the Whitby/OshawalCourtice urban areas. The study has
proceeded with ongoing input and information being provided by the Region. The
Region is now in the final steps of Phase 2 of the EA process where a preferred solution
has been identified, they are seeking comments.
1.2 The existing water supply plant (WSP) capacity available for the
Whitby/OshawalCourice urban areas is adequate to satisfy projected growth until 2011
only. After that time additional WSP capacity will be required if growth is to continue in
accordance with the Regional and Local Official Plans. In addition, upgrading of the
Whitby and Oshawa Water Supply Plants are required to satisfy the Safe Drinking
Water Act Regulations which came into effect in 2002 and are to be implemented by
2005.
2.0 PREFERRED SOLUTION
2.1 The information package (attachment 1) from the Open House recently held for the EA
process details the process, alternative solutions and evaluation that have taken place
to date. From the evaluation the preliminary preferred solution is upgrading/expansion
of the Whitby WSP with supplementary supply from the AjaX/Pickering water system.
The preferred solution does not require any works within Clarington; however it does
affect the timing and ability to continue urban growth in Courtice. This preferred solution
would ensure adequate water supply and capacity to the Courtice Urban Area including
any minor boundary adjustments that may result from the Durham Official Plan review.
3.0 CONCLUSION
3.1 Subject to the comments received as a result of the Open House and the advertised
notice the Region intends to confirm a preferred solution and proceed with evaluation of
alternative designs for the preferred solution in accordance with the Class EA. Since
the preferred solution would ensure adequate water supply and capacity to the Courtice
Urban Area staff are recommending that Council endorse the preferred solution.

INFORMATION PACKAGE
INTRODUCTION
The Regional Municipality of Durham is undertaking a Class Environmental Assessment (Class EA) to
identify the preferred method of providing additional water supply plant capacity for the Whitby,
Oshawa and Courtice Urban Areas, These areas are currently supplied with treated water from the
Whitby and Oshawa Water Supply Plants. At the present rate of development, demands in these urban
areas will exceed the total existing water supply plant capacity in approximately ten years. Additional
water supply plant capacity will be required by that time.
In addition to the need for additional capacity. the Whitby and Oshawa Water Supply Plants will require
operational modifications in the near future to satisfy recently enacted provincial regulations. This Class
EA is being undertaken at the present time to ensure that these operational modifications are compatible
with any plans to provide additional water supply plant capacity in the future.
The Regional Municipality of Durham has retained TSH Consulting Engineers to assist with the
undertaking of this Class EA.
THE PROBLEM
The existing water supply plant capacity available for the Whitby/Oshawa/Courtice urban areas is
adequate to satisfy projected growth until 2011 only. After that time additional WSP capacity will be
required if growth is to continue in accordance with the Regional Official Plan. Additional treated
water storage capacity will be required at the same time to serve the Zone I Water Pressure District
Upgrading of the Whitby and Oshawa WSP's is required to satisfy the requirements of the Safe
Drinking Water Act, which came into effect in 2002. These upgrading works are to be completed by
2005. New works constructed as part of the upgrading must be compatible with future development of
the WSP sites. Planning to determine the optimum configuration of the future plants must be completed
prior to design of the major upgrading works.
Algae blooms in the sununer months have resulted in rapid filter clogging at the Whitby WSP,
requiring increased frequency of backwashing. There is a limited volume of treated water storage
available at the Whitby WSP. These factors have resulted in a reduction in the plant capacity during
the peak consumption period.
A separate Industrial Raw Water pumping system is installed in the former decommissioned plant at the
Whitby WSP site. This system supplies raw (untreated) water for process use to three major nearby
industries via dedicated pipelines. The existing Industrial Raw Water Supply facilities are in poor
condition and lack automatic controls. adequate back-up facilities and standby power. Upgrading and
expansion of these supply works is required to ensure a reliable supply to existing customers and to
provide additional supply for other interested customers.

ENVIRONMENTAL ASSESSMENT PROCESS
Planning for the project is proceeding in accordance with the Municipal Class Environmental
Assessment (Class EA), dated June 2000. The project is designated as a Schedule "c" undertaking,
under the Class EA. Schedule "c" projects are those with significant potential impacts which require a
complete five phase planning and design process with public involvement, including preparation of an
Environmental Study Report (ESR) that is filed for public review.
The Class EA process provides for public and review agency input to allow all concerns to be identified
and addressed when evaluating the alternative solutions. The purpose of this Public Information Centre
is to provide information about the project and to receive public input so that any concerns can be
addressed prior to selection of a preferred solution. A l4-day period is allowed following this Public
Information Centre for receipt of public comment.
ALTERNATIVE SOLUTIONS
The alternative solutions available to address the problems are described below:
Do Nothing
For this alternative, the capacities of the existing Whitby and Oshawa water supply plants would be
maintained at their currenr,.rates and no additional capacity would be provided. The maximum
population that could be serviced by the existing plants is 300,000. This population is expected to be
reached by 2011 and no further development would be possible after that time. The Regional Official
Plan (ROP) provides for growth in the Whitby/Oshawa/Courrice urban areas to 378,000 by 2021. This
alternative is not consistent with the objectives of the ROP and will not be considered further.
Limit Growth
The Regional Official Plan (ROP) provides for growth in the Whitby/Oshawa/Courtice urban areas to
378,000 by 2021. The Official Plan has been prepared in accordance with the Planning Act with public
input throughout, taking into account the various planning factors, and has been adopted by Regional
Council. This alternative is not consistent with the objectives of the ROP and will not be considered
further.
Demand Management
Demand management may be used to achieve more efficient use of water in order to free up capacity to
serve additional development. Demand management methods include water metering, user-pay water
rate structures, reduction of system leakage, provision of water efficient fixtures, water use restrictions
and public awareness programs. The Regional Municipality of Durham has had a comprehensive
Water Conservation program in place since the mid 1990's that has led to more efficient water use
throughout the Region. This program will continue.
This alternative does not adequately address the long-term water demand issues as identified in the
opportunity statement and will not be evaluated as a stand.alone solution. The continuance of the
Region's Water Conservation program is part of good environmental stewardship and it is
t~ ';

recommended that it continue in the future as a component of the preferred alternative for providing
additional water supply for the Whitby/Oshawa/Courtice Urban Areas.
Upgrade/Expand Existing Water Snpply Plants
The net maximum day water supply capacity of the Whitby and Oshawa WSP's during the peak period
of smmner water use is 232 MUd (5I.lMIGD). This is adequate to meet projected demands in the
Whitby/Oshawa/Courtice urban areas until 2011. Additional WSP capacity will be required by 2011 to
satisfy increased demands after that date.
The net capacity of the Whitby WSP in the summer is 109 MUd (24MIGD). The plant is supplied by a
single 1372mm diameter intake that has an assumed maximum estimated capacity of 230 MUd
(50.6MIGD). The Region intends to undertake flow tests in the near future to verify the intake
capacity. The Whitby WSP currently has the capability to also supply approximately 9.5 MUd
(2IMIGD) of untreated water to a separate raw water system that supplies local industries. The
current maximum day demand of the raw water system is approximately 6,7 MUd (1.5MIGD). and
recent studies indicate this demaud may ultimately increase to approximately 39.3 MUd (8,6MIGD).
The net capacity of the Oshawa WSP in the summer is 123 MUd (27.lMIGD). The plant is supplied
by two 750mm diameter and 900mm diameter intakes that have a combined maximum estimated
capacity of 135 MUd (29.7MIGD).
Expausion of tlle Whitby and Oshawa WSP's are feasible options. For the Whitby WSP, the eXisting
site would be able to accommodate an expansion of the WSP to the ultimate required capacity of 327
MUd (72.0MIGD). Por the Oshawa WSP, the existing site provides limited opportunity for expansion,
and off-site land acquisition would likely be required to accommodate expansion of the WSP to the
ultimate required capacity of 327 MUd (72.0MIGD).
The upgrading/expansion works to be provided initially should be designed, at a minimum, to meet the
supply requirements for a IO-year design period. i.e, until 2021, assuming expansion in 2011. In
accordance with sta!ldard design practice, provision should be made to accommodate future
upgrading/expansion works to meet requirements for a 20-year design period, I.e. until 2031, assuming
expansion in 2011.
With regard to major plant sites, such as the sites of water supply plants, it is important to ensure that
the property is large enough to accommodate undetermined future capacity requirements, I.e. beyond
2031. Section 5.3.17 of the Regional Official Plan (ROP) allows the Region to plan for land
requirements for major water supply and sanitary sewerage infrastructure (e.g. water supply plants) to
provide servicing capacity beyond tlle population targets and related employment targets indicated in tlle
ROP
Supplement Supply from Adjacent Water Supply System
The Harwood Pumping Station provides a connection between the Whitby /Oshawa/Courtice distribution
system and the Ajax/Pickering distribution system. Historically, the Harwood PS has been able to
transfer a maximum flow of approximately 40 MUd (9 MIGD) westward from the
Whitby/Oshawa/Courtice system to the Ajax/Pickering system. However, this was achieved prior to
the commissioning of the Ajax WSP and also prior to improvements to the feederrnains on the
Ajax/Pickering system, which are likely to impact the maximum flow that the Harwood PS can

transfer. This pumping station does not currently have the capability to transfer flows eastward from
the Ajax/Pickering system to the Whitby/Oshawa/Courtice system. The pumping station was designed
to allow for modifications to enable it to supply a capacity of approximately 55 ML/d (12 MIGD) either
westward or eastward. This option is feasible as an interim measure to allow transfer of surplus water
supply in either direction in order to defer a required water supply plant expansion,
Develop New Water Supply Plant
Since there are three existing sources of supply, with potential for expansion to meet the future
requirements after 20 I I, construction of a new WSP is not considered to be a viable alternative at this
time.
EVALUATION OF FEASIBLE ALTERNATIVES
The feasible alternatives selected for detailed evaluation are:
Alternative 1: Upgrade/Expand Whitby WSP
Alternative 2: Upgrade/Expand Oshawa WSP
Altemative 3: Supplement Supply from Ajax/Pickering water system
Alternative 1: Upgrade/Expand Whitby WSP
For this option the Whitby WSP net capacity would be increased from 109ML/d (24.0MIGD) to
191ML/d (42.0MIGD); the Oshawa WSP capacity would be unchanged. Based upon projected demand
growth, this expansion would be required in 20 II and would satisfy demands in the
Whitby/Oshawa/Courtice urban areas until 2023. Additional water supply capacity would be required
after that time.
The works required at the Whitby WSP site to provide this additional capacity would include:
. Provision of additionallow lift pumping capacity
. Provision of settling tanks ahead of existing filters
. Provision of additional flocculation tanks, settling tanks and filters
. Addition of GAC to filters for taste and odour control
. Provision of additional treated water storage
. Provision of additional high lift pumping capacity
. Provision of additional standby power facilities for the WSP
. Provision of additional backwash treatment facilities
Due to the poor condition of the existing Industrial Raw Water Supply system and the potential need to
expand the system, this alternative would also include provision of new and expandable Industrial Raw
Water pumping facilities,
The existing Whitby WSP site area is adequate to accommodate the additional works required to
provide a net capacity of 191ML/d (42.0MIGD) and potential future expansion to an ultimate target
capacity of 327ML/d (72.0MIGD). Alternatively, the undeveloped lot on the north side of Water Street
opposite the Whitby WSP, could be considered for future site expansion. This property is owned by
the Town of Whitby.

The assumed capacity of the existing intake is 230ML/d (50.6MIGD), subject to confirmation by flow
testing to be undertaken by Regional staff For a net plant capacity of 191ML/d (42.0MIGD), the
required intake capacity would be as follows:

230ML/d
Additional intake capacity wonld be required after 2028 to accommodate any additional water supply
plant capacity expansion.
Trunk watermain (feedermain) improvements would be required to convey the additional flows to the
Zone 1 Water Pressure District reservoirs.
Alternative 2: Upgrade/Expand Oshawa WSP
For this option the Oshawa WSP net capacity would be increased from 123MlId (27.1MIGD) to
205ML/d (45.1MIGD); the Whitby WSP capacity would be unchanged. Based upon projected demand
growth, this expansion would be required in 2011 and would satisfy demands in the
Whitby/Oshawa/Courtice urban areas until 2023. Additional WSP capacity would be required after that
time.
The works required at the Oshawa WSP site to provide this additional capacity would include:
. Provision of additional intake capacity
. Provision of additional low lift pumping capacity
. Provision of additional flocculation tanks, settling tanks and filters
. Addition of GAC to filters for taste and odour control
. Provision of additional treated water storage
. Provision of additional high lift pumping capacity
. Provision of additional standby power facilities for the WSP
. Provision of additional backwash treatment facilities
Filter backwash water is currently discharged to Lake Ontario untreated. Backwash treatment facilities
to remove particulate matter, are to be provided at the Oshawa WSP site as part of the upgrading works
to be completed by 2005. A preliminary location for these works has been identified at the south side of
the existing water supply plant,
The existing Oshawa WSP site area is not adequate to accommodate the additional works required to
provide a net capacity of 205M Lid (45.1MIGD) or potential future expansion to an ultimate capacity of
327ML/d (72.0MIGD). There are two potential expansion areas adjacent to the existing site; an
undeveloped lot to the north, owned by the Region of Durham and a park on the east side of the
existing site, owned by the City of Oshawa.

The existing intake capacity is adequate for a gross plant capacity of 135ML/d (29.7MIGD.For a net
plant capacity of 205M Lid (45,IMIGD), the required intake capacity would be as follows:

Trunk watermain (feedermain) improvements would be required to convey the additional flows to the
Zone I Water Pressure District reservoirs.
Alternative 3: Supplement Supply from Ajax/Pickering Water System
The Harwood Pumping Station can be used to transfer surplus flow westward from the
Whitby/Oshawa/Courtice water system through a 750nun dia. transmission main to the Ajax/Pickering
water system. The pumping station cannot currently transfer flow eastward; however, it was designed
to allow for modifications to enable it to supply a capacity of approximately 55 MLld (12.0MIGD)
either westward or eastward.
Both the Ajax/Pickering and Whitby/Oshawa/Courtice water systems will require additional water
supply plant capacity by 2012. Use of the Harwood Pumping Station to transfer water between the
systems would allow for deferment of some future plant expansions by up to 8 years.
Scenario I: Initial Supplementary Supply from Ajax/Pickering
For this scenario the Ajax/Pickering WSP would be expanded by 2012 to a capacity of 327MLld
(72.0MIGD). At the same time the Harwood Pumping Station would be modified to pump up to
50MLld (11.0MIGD) eastward from the Ajax/Pickering system to the Whitby/Oshawa/Courtice
system. In 2019 the capacity of the Harwood Pumping Station would be reached and the Whitby or
Oshawa WSP would be expanded to a minimum combined capacity of 314ML/d (69. I MIGD) ,
Transfer of water from the Ajax/Pickering system to the Whitby /Oshawa/Courtice system would
resume in 2024 to satisfy the supply deficit in that system. By 2029 the Whitby/Oshawa/Courtice
system would require additional water supply capacity.
Scenario 2: Future Supplementary Supply from Aiax/Pickering
For this scenario the Whitby or Oshawa WSP would be expanded by 2012 to a minimum combined
capacity of 314MLld (69,IMIGD). Commencing in 2013 surplus capacity would be pumped via the
Harwood Pumping Station to the Ajax/Pickering system to satisfy the supply deficit in that system.
When the capacity of the existing pumping station is reached, sometime before 2020, the Ajax WSP
would be expanded to a capacity of 327MLld (72.0MIGD). By 2024 the Whitby/Oshawa/Courtice
system would require additional water supply. At that time the Harwood Pumping Station would be
modified to pump up to 50MLld (11.0MIGD) eastward from the Ajax/Pickering system to the
Whitby/Oshawa/Courtice system and surplus flow would be pumped to the Whitby/OshawalCourtice
system to satisfy the supply deficit in that system. By 2029 the Whitby/Oshawa/Courtice system would
require additional water supply capacity.

PREFERRED ALTERNATIVE
An Evaluation Sunnnary for the three alternatives is attached. The preliminary preferred solution is
upgrading/expansion of the Whitby WSP with supplementary supply from the Ajax/Pickering water
system. The preferred solution would require the following works:
. Upgrading and expansion of the Whitby WSP
. Replacement of the Industrial Raw Water Supply System
. Upgrading of the Harwood Pumping Station
. Provision of new feedermains
FUNDING OF COSTS
Capital costs for improvements that are required to correct existing deficiencies would be recovered
from existing and future users via the user rates, Capital costs for improvements that are required to
service future growth would be recovered from new users via development charges, assessed against
the developers.
