SUBJECT: Old Mill Road Forcemain Replacement
RECOMMENDATION:
That the tender selection requirements of the purchasing policy for the selection of
Engineering Consultants be waived and that MTE Consultants Incorporated be retained
as the Engineering Consultant for the City to undertake the detailed design and contract
administration for the Old Mill Road forcemain replacement project and further;
That the Mayor and Clerk be authorized to execute an Engineering Agreement for the
provision of professional engineering services between the City of Kitchener and MTE
Consultants Incorporated at a total cost of $52,000.00 including applicable taxes and
further;
That $282,000.00 be allocated from the Sanitary Sewer Utility to the Old Mill Road
Forcemain Replacement project account to complete the project.
EXECUTIVE SUMMARY:
The City of Cambridge undertook a Class EA to determine the preferred alignment for servicing
the Conestoga College and Blair Industrial Lands. During the detailed design it was identified
that the City of Kitchener's existing forcemain should be replaced as part of Cambridge's project
scope due to the condition, age and future capacity of the existing sanitary forcemain.
The staff recommend that MTE Consultants Inc. be appointed to complete the detailed design
and contract administration to replace the City's forcemain from the Old Mill Pumping Station to
the Wastewater Treatment Plant.

BACKGROUND:
In March 2007, the City of Kitchener was approached by Conestoga College and the City of
Cambridge to explore the potential to service the proposed South Campus for Conestoga
College along with the Blair Industrial Business Park. It was determined that a viable option
would be to service the lands by directing the sewage flow from Cambridge to the Kitchener
Wastewater Treatment Plant in accordance with the Region of Waterloo Wastewater Master
Plan.
In May 2009, City of Cambridge initiated a Class "B" Environmental Assessment to determine
the preferred design and alignment of the sewage outlet to the Kitchener Wastewater Treatment
Plant in order to service the Conestoga College and Blair Industrial Business Park Lands. The
City of Cambridge hired MTE Consultants Inc. to complete the Class EA Study. The preferred
alignment includes a gravity sewer system from the Blair Business Park to a new Sanitary
Pumping Station that is located at the northwest corner of Fountain Street and Morningside
Drive (City of Cambridge), and a sanitary forcemain routing along Morningside Drive and
crossing Highway 401, then crossing the North Campus of Conestoga College (Donn),
continuing along Doon Valley Drive and then Old Mill Road, crossing Schneider Creek and
ultimately outletting to the Kitchener Wastewater Treatment Facility. The Environmental Study
Report (ESR) and the preferred alignment were approved by City of Kitchener council on
September 21, 2009 and then City of Cambridge filed the ESR with the Ontario Ministry of
Environment. (Refer Appendix A, Preferred alignment map)
REPORT:
In March 2010, the City of Cambridge appointed MTE Consultants Incorporated to complete the
detailed design and the contract administration for the Blair pumping station and forcemain. At
this time, MTE Consultants Inc. are currently finalizing the detailed design for the pumping
station and forcemain based on the preferred alignment from the Class EA Study. The design
was coordinated and reviewed by both the City of Kitchener and the City of Cambridge.
Through the design review some concerns were raised in regards to the condition, age and
capacity of the City of Kitchener's existing sanitary forcemain. The existing forcemain 300mm
dia. ductile iron forcemain is approximately 40 year's old and 550 meters in length; it runs from
the Old Mill Pumping Station to the Wastewater Treatment Plant. The City of Cambridge's
consultant MTE recommended to the City of Kitchener Infrastructure Service Department that
the 300mm diameter sanitary sewer should be replaced as part of the Cambridge project due to
age and the structural integrity of the pipe. The City staff (Operation and Engineering section)
reviewed MTE's request and find that this would be an appropriate time to replace the existing
forcemain to reduce future breakages and related environmental impacts (Refer Appendix B,
proposed forcemain). Further, based on future development within the Old Mill pumping station
catchment area the existing forcemain has no additional capacity to support future growth and
development within the area.
Furthermore, the City of Kitchener requested MTE Consultants Inc to investigate the benefits of
replacing the existing forcemain as part of the City of Cambridge's work scope, the benefits are
listed below:

1. If the City of Kitchener decided to replace this forcemain as a separate contract, the
estimated construction cost for the project would be $456,000. However, if the City
decided to replace this pipe with the City of Cambridge project there will be cost savings
of $126,000 on construction costs alone.
2. The cost saving in consulting fees for gathering the background data, geotechnical
investigations, survey and other agencies permit requirements is about $50,000. This
information has been already gathered for the City of Cambridge project.
3. There will be less nuisance to the residents in the area as construction will only be
occurring once for both forcemains.
4. There will be less impacts to Schneider Creek as construction would only occur one
time.
5. Cost and time savings as the City of Cambridge has already received approvals and
permits from both the Grand River Conservation Authority and the Department of
Fisheries to cross the Schneider Creek for this construction work.
Based on the above benefits, Engineering and Operation staff recommend that MTE
Consultants Inc. be appointed to complete the replacement of the forcemain. As part of the
detailed design, MTE Consultants Inc. would facilitate the contract administration and full time
inspection during the construction.
ALIGNMENT WITH CITY OF KITCHENER STRATEGIC PLAN:
The Old Mill Road forcemain replacement project is aligned with the City of Kitchener strategic
plan; refer to strategic plan document, community priorities — Development sections 1 & 3.
FINANCIAL IMPLICATIONS:
The estimated construction cost for the project is $330,000 along with MTE Consultant Inc. fees
of $52,000 which would total $382,000 for the City of Kitchener cost sharing portion of the
project. There is $100,000 in the Old Mill Pumping Station account (52000132) from
Development Charges and an additional $282,000 is requested to be allocated from the
Sanitary Sewer Utility to the Old Mill Road Forcemain Replacement project account to complete
the project. This amount was already included in the 2011 Capital budget forecast.
COMMUNITY ENGAGEMENT:
The City of Cambridge along with MTE Consultants Inc. held two Public Information Centre's
(PIC's) on June 23, 2009 and August 20, 2009 respectively, as part of the Class EA process to
present the study findings and obtain comments from the residences on the project and in
efforts to determine the best alignment for the forcemain. The first PIC had 8 residences in
attendance and the second PIC had 17 residences in attendance.
The City of Kitchener requested the City of Cambridge to conduct a third PIC to present the
detailed design and revised alignment of the forcemains. The PIC will be held on January 25,
2011 with the City of Kitchener and City of Cambridge residents and all issues will be resolved
and taken into consideration prior to construction commencing on site.

The Class EA for the servicing options for Conestoga College and the Blair Business Park
Lands has been completed and approved by Council. At this time staff would like to include the
replacement of the existing sanitary forcemain to the City of Cambridge project scope in order to
avoid potential pipe breakage, and to accommodate future development within the catchment
area.
Therefore staff recommend that the tender selection requirements of the purchasing policy for
the selection of Engineering Consultants be waived and that MTE Consultants Incorporated be
retained as the Engineering Consultant for the City to undertake the detailed design and
contract administration for the Old Mill Road forcemain replacement project
