SUBJECT:
CLASS ENVIRONMENTAL ASSESSMENT (EA) FOR
OTTAWA-TRUSSLER AREA SEWAGE FACILITY
RECOMMENDATION:
THAT the Ottawa-Trussler Area Sewage Facility Environmental Study Report (ESR)
prepared by MMM Group Limited, dated Dec, 2013, be received; and further
THAT the Ottawa-Trussler Area Sewage Facility Environmental Study Report (ESR) be
filed with the Ministry of the Environment for the mandatory thirty (30) day review period
as required by the Environmental Assessment (EA) Act.
BACKGROUND:
In accordance with the Kitchener Growth Management Plan and the 2004/2009 Development
Charge Background studies, the City of Kitchener is planning to develop the Laurentian West
Phase 3b Community and surrounding area. In order to support development within this area,
the City is required to complete a “Schedule B” Class Environmental Assessment Study (EA) to
identify a location for a new sanitary pumping station, forcemain, and other related infrastructure
upgrades.
Activa Holdings Inc. agreed to pay the cost of the consultant to be retained by the City to
complete the Class EA study, to be recovered through a Credit for Service Agreement. In
accordance with the June 25, 2012 Council recommendations, the City entered into a Credit for
Service agreement with Activa Holdings Inc., for the cost to complete the Class EA study.
In keeping with September 17, 2012 Council recommendations, the City of Kitchener appointed
MMM Group Limited as the City’s consultant to complete the Class Environmental Assessment
for the Ottawa-Trussler Area Sewage Facility.
The Class EA study prepared by MMM Group Limited has derived an appropriate catchment
area for the sanitary sewer pumping station and evaluated wastewater servicing alternatives for
servicing growth in the Laurentian West Phase 3b community and surrounding area.
1 - 1
The study identifies and defines a suitable sanitary sewer servicing solution to support the
development in Laurentian West Phase 3b Community and surrounding areas. These areas
include undeveloped lands within the existing approved Urban Boundary, and existing residences
within the Urban Boundary along Trussler Road and Ottawa Street South (see Appendix A).
Within the purpose of this study, the following objectives have to be achieved:
a) Protection of the environment, as defined in the Environmental Assessment Act, through the
wise management of resources. Met through monitoring, mitigation, and consultation with all
affected and interested parties.
b) Minimal disruption to existing residents and travelers during construction.
c) Participation of a broad range of stakeholders in the study process to allow for sharing of ideas,
education, testing of creative solutions, and development of alternatives.
d) Documentation of the study process in compliance with all phases of the Municipal Class
Environmental Assessment Schedule “B” process.
The study has selected a preferred alternative and conceptual design for the Ottawa-Trussler
Area Sewage Facility, related forcemain and required downstream sewer upgrades, by
.
generating and evaluating various alternatives while considering environmental effects
REPORT:
A key objective of the study is to protect the environment, as defined in the Ontario
Environmental Assessment Act (EA Act), through the wise management of resources. This has
been achieved by identifying appropriate mitigation and monitoring measures to minimize the
potential adverse environmental effects. In addition, the participation of a broad range of
stakeholders in the study process has allowed for the sharing of ideas and identification of
creative solutions that are acceptable to affected and interested parties.
A number of alternative solutions were developed to address the problem/opportunity statement
as summarized in Table ES1.

These alternative solutions (excluding Alternatives 3 and 6 – which were screened out at an
earlier stage) were evaluated against a set of defined evaluation criteria covering the Natural
Environment, Sociocultural Environment, Construction, Financial and Technical categories.
The preferred alternative was determined to be Alternative 2A. In comparison to other
alternatives, Alternative 2A performs better against socio-cultural criteria, construction criteria,
financial criteria and technical criteria. While the Do Nothing does not result in any potential
adverse environmental effects, it clearly does not address the problem/opportunity and study
objectives, and does not provide the necessary infrastructure to support future servicing needs
or City-wide growth targets.

Preferred Alternative
The recommended Pumping Station design as depicted in Appendix B, integrates form and
function into a unified and compact structure; incorporating architectural, landscaping and
security features to enhance its visual appearance and help the facility integrate within the
proposed Activa Trussler North Subdivision (ATNS). The recommended facility design is based
on an ultimate peak pumping capacity and would include an automated pumping system with
Supervisory Control and Data Acquisition (SCADA) integration, emergency wastewater storage,
a diesel powered emergency generator, and appropriate odour, emissions and noise controls.
The Sanitary Sewer flow collected at the pumping station will be pumped through a dedicated
250 mm diameter sewage forcemain, which exits the pumping station site as shown Appendix
B.
The proposed forcemain will be routed initially along roadways within the proposed ATNS and
then routed within the Ottawa Street South right-of-way (shown in Appendix B), initially passing
the Region of Waterloo Mannheim Water Treatment Plant, water storage facility and buried
water transmission infrastructure.
Following a carefully planned and designed route along the existing Ottawa Street South right-
of-way, the forcemain will pass existing and future residential lands, open areas as well as
environmentally sensitive lands. The forcemain design will incorporate appropriate mitigation
measures and controls to protect all adjacent and nearby lands as required during and following
construction activities.
The sewage forcemain is designed to connect into the City of Kitchener’s existing gravity sewer
system, currently proposed to be at the intersection of Ottawa Street South and David Bergey
Drive, as shown in Appendix B.
This connection point was determined to have sufficient local and downstream capacity, verified
using the City’s InfoSWMM sanitary sewer model to hydraulically analyze the impact of the new
pumping station flow and other local inputs on the City’s existing sewer network.
Mitigation measures have been identified to mitigate potential adverse environmental effects
related to the preferred alternative. As part of overall implementation and monitoring and to
ensure long-term operation and servicing goals will be achieved, the City is planning to monitor
flow in the vicinity of the discharge point. This will allow the City to measure the combined flow
from the new Pumping Station and all adjoining catchment areas. This will help to proactively
assess the need for any future system enhancements or upgrades to accommodate future
growth and increased sewage flow from the Laurentian West Phase 3B area as outlined in
Kitchener’s Growth Management Plan (KGMP).
ALIGNMENT WITH CITY OF KITCHENER STRATEGIC PLAN:
The Ottawa-Trussler Sewage Facility project is aligned with the City of Kitchener Strategic Plan
(refer to Strategic Plan document, Community Priorities – Development, sections 1 & 3).
Further, this project is also one of the priority projects identified in the Kitchener Growth
Management Plan, as it provides service to lands identified as Priority B.
FINANCIAL IMPLICATIONS:
This project was identified in the City’s 2009 Development Charge Background studies and in
the City’s 2014 Capital Forecast for implementation in 2020. The project is to be funded 100%
from Development Charges, with an estimated cost for the preferred Alternative 2A to be
$4,557,776.

COMMUNITY ENGAGEMENT:
The EA study involved the following public and agency stakeholder consultation:
Project team met with interested agencies including: City of Kitchener Departments, Region
of Waterloo, Town of Wilmot and Grand River Conservation Authority to discuss the EA, the
proposed servicing for neighbouring areas, land use, environmental constraints including the
existing well head protection areas for the Mannheim WTP, serviceable lands and current
and proposed development initiatives within the area.
Notice of Commencement – to introduce the study; this was mailed to residents within the
study area, identified stakeholders, and published in The Record.
Public Information Centre (PIC) # 1, May 7, 2013 – the PIC notice was mailed to residents
within the study area, identified stakeholders, and published in The Record. PIC 1 focused
on the study scope and objectives, the technical investigations to be undertaken, and
information on the preliminary criteria for evaluating the alternatives.
Public Information Centre # 2, September 25, 2013 – the notice was mailed to residents
within the study area, identified stakeholders, and published in The Record. PIC 2 focused
on the evaluation of alternative solutions and the preliminary preferred alternative.
Presentation of the study findings and preferred alternative to the City of Kitchener
Environmental Committee on October 17, 2013.
CONCLUSION:
In accordance with Class Environmental Assessment process together with studies and detailed
assessment completed by the Consultant Team, the Project Team has selected a preferred
alternative, which was presented to stakeholders and residents on September 25, 2013 and to
the City of Kitchener Environmental Committee on October 17, 2013.
There were two PIC’s and other consultation process mechanisms used to solicit stakeholder
input to review the study findings and receive comments on this project. As part of the Class EA
process, staff also met with various agencies and affected property owners to address their
concerns. In conclusion, staff recommend that the Ottawa-Trussler Area Sewage Facility Study
Report (ESR) prepared by MMM Group Limited, dated December, 2013 be received.
Further, staff recommend that the Ottawa-Trussler Area Sewage Facility Study Report (ESR) be
filed with the Ministry of the Environment (MOE) for the mandatory thirty (30) day review period,
as required by the Environmental Assessment (EA) Act.
