rapport présent.
Background
The Ottawa River Action Plan (ORAP) consists of 17 individual projects aimed at improving the health of the Ottawa River and protecting the health of Ottawa’s water environment for future generations. Implementation of the Plan is progressing into its second year and the purpose of this report is to provide an update on the status of all ORAP projects as committed by ESD in the ORAP Report, ACS2010-ICS-ESD-0007, approved by Council on February 24, 2010.
Council approved a five-year $251.64 million Ottawa River Action Plan that takes a watershed-based approach to protect and improve the quality of the Ottawa River. Council deemed ORAP to be the most effective course of action to improve the river quality, meet the public’s expectations and provides the best return on investment that exceeds provincial requirements. The Plan considers all municipal impacts on the Ottawa River and addresses the impacts using a cost-effective approach.
The objectives of ORAP are the following:
• Achieve and sustain compliance with provincial requirements, with a focus on combined sewer overflow (CSO) control;
• Optimize recreational use and economic development of the river, with a focus on reducing beach closures;
• Maintain a healthy aquatic ecosystem, with a focus on addressing challenges presented by existing infrastructure; and,
• Develop a long-term Water Environment Strategy.
To achieve the objectives, ORAP focuses on the following major elements:
• Reducing combined sewage overflows;
• Reducing stormwater impacts;
• Improving wastewater treatment; and,
• Measuring and monitoring our performance.
DISCUSSION
All projects are moving forward
and the majority are on-schedule. This report
presents the status of each project in accordance with the major elements of
ORAP’s focus. In addition to the
detailed project summaries described in the following paragraphs, a “Quick
Indication” of each project status is
provided in Table A, attached.
Reducing Combined Sewage Overflows
The first element of the plan is reducing combined sewer overflows and consists of projects in three phases. Projects 1, 2, 4, 5, 6, 7 and 8 make up the first two phases. Project 3 is the third and final phase. Projects 1 through 8 are focused on providing a service level for combined sewer overflows of zero overflows during the swimming season in an average year.[1] These projects are:
Project 1:
Implementation of Real Time Controls
Project 2:
Critical CSO and Storm Outfall Monitoring
Project 3:
CSO Storage in the Ultimate Combined Sewer Area
Project 4:
Review and Implement Sewer Interconnection Program
Project 5:
Sewer Separation Outside the Ultimate Combined Sewer Area
Project 6:
Development of a Wet Weather Infrastructure Management Plan
Project 7:
Implementation of the Wet Weather Infrastructure Management Plan
Project 8:
Installation of Floatable Traps in Combined Sewer Area Catchbasins
Project 1: Implementation of Real Time Control (RTC) was the first ORAP project completed, and has already improved the River noticeably by reducing CSOs. The RTC project consisted of major upgrades to five CSO regulators including new gates, electrical and instrumentation controls, and flow monitoring and measurement equipment. Continuous, real-time adjustment of gate positions at three of these regulators maximizes the amount of CSO captured by the existing sewer system.
The total CSO volume for the 2010 control period is estimated to be 443,000 cubic metres. In order to compare the effect of real time control on CSO volumes a performance measurement of CSO volume to precipitation was used. Using this performance measurement 2010 saw 30% less CSO volume per millimetre of rain than 2009, and 50% less CSO volume per millimetre of rain than 2006 when CSO volumes were initially reported.[2]
Project 3: CSO Storage for the Ultimate Combined Sewage Area will bring the City beyond all Ministry of the Environment requirements for the capture and treatment of combined sewer overflows. This project is currently within the environmental assessment and functional design phase, and the developed design solution consists of the following major components:
Together, the first two components will provide sufficient storage to
achieve CSO control of zero overflows in an average year. The third component will provide even more
CSO storage and will greatly enhance system redundancy and operational
flexibility. It is proposed as a
subsequent phase and is contingent on obtaining funding; it is not included in
the ORAP budget of $251.64 million. As
this project moved forward, a significant opportunity was realized and
potential barriers developed.
The scope of service for this project increased by seizing an opportunity
to integrate the proposed flood control strategy for the combined sewer area
(CSA) with CSO storage. As a result, during
extreme weather events the north-south tunnel along Kent Street can also be
used as a major flood relief pipe to channel excessive stormwater from areas
within the downtown core that are at risk of flooding.
A major constraint of this project is securing land for the proposed tunnel
alignments, as most of the land is federally owned. To date, Senior City Management continues to
meet with the National Capital Commission (NCC) to attempt to secure land and
easement agreements. This has caused
delays to the project, and as a result completion of the Environmental Study
Report and Functional Design are approximately eight months behind schedule. Construction
funding is another project constraint, which is discussed in more detail in the
Financial Status section of this report.
The following projects are also focused on reducing combined sewer
overflows and/or the amount of pollutants contained in CSOs:
Project 2: Critical CSO and
Storm Outfall Monitoring;
Project 4: Review and Implement Sewer
Interconnection Program;
Project 5:
Sewer Separation Outside the Ultimate Combined Sewer Area; and,
Project 8: Installation of Floatable Traps in Combined
Sewer Area Catchbasins.
These projects are progressing well and are not experiencing “barriers” to their success. Note that Project 5 will be on-going for the next 20 to 30 years.
Projects 6 and 7: Development and Implementation of a Wet Weather Infrastructure Management Plan (WWIMP) are behind schedule due to the lack of staffing resources available to manage these projects. Engineering staff originally dedicated to the WWIMP are currently committed to the West End Flooding investigation. The original completion date for development of the WWIMP was end of year 2010, but it is anticipated that development will extend into 2012.
Reducing Stormwater Impacts
The second major element of ORAP is reducing stormwater impacts in order to reduce beach closures and maintain healthy acquatic ecosystems. Projects 9, 10 and 11 are focused on stormwater management:
Project 9:
Pinecrest Creek / Westboro Stormwater Management Retrofit Plan
Project 10:
Eastern Subwatersheds Stormwater Management Retrofit Plan
Project 11:
Implementation of Stormwater Management Retrofit Plans
The Pinecrest Creek / Westboro Stormwater Management Retrofit Plan will mitigate the impacts of uncontrolled stormwater runoff on Pinecrest Creek and the Ottawa River, and this project also serves as a pilot to develop a methodology to be applied to future stormwater management retrofit plans within the urban area. The Retrofit Study was recently completed and is scheduled to be presented to Committee/Council in Q3-Q4 2011.
Key recommendations from the study include:
·
Implementing stormwater management
retrofits to improve water quality and reduce beach closures, creek flooding
and erosion.
·
Retrofit measures include new stormwater
facilities; retrofitting some roads into “green streets” (e.g., pavement
narrowing, tree planting, pervious sidewalks, etc.); promoting measures for
homeowners to contribute to the solution (rain barrels, rain gardens, pervious
driveways, etc.); and providing public education and programs/incentives to get
homeowners and businesses involved in the solution.
·
Implementing various measures over a
period of time based on financial resources on both public and private
properties.
The
knowledge and lessons learned from the Pinecrest Creek / Westboro Retrofit
Project will be conveyed to Project 10:
Eastern Subwatersheds Stormwater Retrofit Plans. The Eastern Subwatersheds include Billberry,
Voyageur, Taylor, and Green’s Creeks and water quality computer modelling of
the Ottawa River identified these creeks as contributing factors to beach
closures at Petrie Island. Preliminary
work has begun on the Eastern Subwatershed studies, and this project is
on-track to meet its planned completion date of year end 2012. Implementation of the Stormwater Management
Retrofit Plans will be subject to future budgetary approvals.
Improving Wastewater Treatment
Wastewater Treatment Plant enhancements is the third component to achieve ORAP’s objectives. Project 12: R.O. Pickard Environmental Centre Effluent Dechlorination is focused on improving treated wastewater discharged to the Ottawa River. Currently, chlorine is used as a final disinfectant of treated wastewater during the summer season. The new dechlorination facility will reduce chlorine levels within the treated wastewater effluent below pending federal regulation limits.
Design of the dechlorination facility is complete, and construction commenced in April of this year. Construction and final commissioning of the new facility is planned for December 2011. This project was originally scheduled for completion by the end of 2010 in order to comply with the pending federal regulations, but the regulations have not yet been finalized, or registered. This delay allowed the project stakeholders to incorporate design modifications to the existing chlorination facility into the contract, thereby achieving construction efficiencies. The revised project completion date of December 2011 will provide ample time for the City to meet this regulatory obligation.
Measuring and Monitoring Our Performance
The last component of ORAP is measuring and monitoring the City’s performance and developing a long term water environment strategy. The following projects are focused on these initiatives:
Project 13:
Develop and Implement a Water Environment Strategy
Project 14:
Monitoring and Source Control Programs
Project 15:
Wastewater and Drainage Environmental Quality Management System
Project 16:
Updates to the Bacterial Water Quality Computer Model
Project 17:
Public Outreach and Education
The objectives of Projects 13, 15, and 17 are to develop long-term water environment strategies, improve the way we do business, and continue to engage and educate the public on the water environment in order to protect and preserve the City’s water resources.
Project 13: Develop and Implement a Water Environment Strategy is progressing well and the strategy objectives, program areas, prioritized actions, and top line budget are on track to be delivered by the end of 2011. The Strategy will be brought before Committee/Council to be endorsed, and the Implementation plan is scheduled to commence in 2012.
Project 15: Wastewater & Drainage Environmental Quality Management System (EQMS) will allow the City to manage its wastewater and drainage business activities in a transparent and accountable manner. The EQMS is aligning itself with the Corporate Service Excellence Program and Corporate Risk Management Program, but competing department priorities have resulted in project delays. Originally scheduled to be completed by year-end 2010, the core EQMS system is approximately 75% complete and the revised completion date is year-end 2011. Implementation is scheduled to begin in 2012.
Project 17: Public Outreach and Education is progressing well and a Water Environment “road-show” was carried out in 2010 to understand the public’s general knowledge of the water environment in order to gauge future outreach and education programs. This project is on-track and the range and priority of communication needs are currently being developed.
Project 14: Monitoring and Source Control Programs and Project 16:
Updates to the Bacterial Water Quality Computer Model are both ongoing
initiatives that will continue over the duration of ORAP and beyond. The continued implementation of the City’s
Water Environment Protection Program will allow the City to assess trends in
the water environment. The continued
implementation of the Sewer Use Program will proactively seek out contamination
at its source and prevent it from entering the water environment. Updates to the Ottawa River Model will
enhance model calibration as well as using the model for parameters other than
E. coli. This tool is imperative to
assess CSO and stormwater inputs, as well as to identify priorities and
evaluate improvement strategies.
Financial Status
The funding status of all ORAP projects, including a summary of the five-year spending plan is provided in Table A below. Of the 17 projects, five are shown in Table A with either approved and/or forecasted funding commitments that exceed ORAP’s five-year spending plan (2009 to 2013). These projects are:
Project 3:
CSO Storage in the Ultimate Combined Sewer Area
Project 5:
Sewer Separation Outside the Ultimate Combined Sewer Area
Project 7:
Implementation of the Wet Weather Infrastructure Management Plan
Project 14:
Monitoring and Source Control Programs
Project 16:
Updates to the Ottawa River Bacterial Water Quality Computer Model.
Project 3: CSO Storage in the Ultimate Combined Sewer Area is anticipated to exceed its original budget. Integrating CSA flood relief with the CSO storage project partially contributed to the project budget increasing from $140 million to $150 million, but the expected long term cost savings as a result of integrating these two initiatives is estimated at $40 million. The cost of this project will become more precise as the project moves into the preliminary design phase and the land acquisition costs become clear. As mentioned previously, construction funding is a project constraint at this time. The City is seeking one-third funding contributions from both the Federal and Provincial governments for the cost of construction, with the City providing the final third. The City continues to pursue commitments from these two upper levels of government.
Project 5: Sewer Separation Outside the Ultimate Combined Sewer Area is on target to achieve the originally forecasted sewer separation spending plan, and is currently expected to slightly surpass the original budget by $0.9 million. Sewer separation costs will continue to be tracked within the overall integrated replacement program.
Project 7: Implementation of the Wet Weather Infrastructure Management Plan includes previously approved funding for other wet weather related initiatives that were combined into this project for overall coordination.
Project 14: Monitoring and Source Control Programs and Project 16: Updates to the Ottawa River Bacterial Water Quality Computer Model were increased to initiate additional water quality modelling in the Eastern Subwatershed studies and to anticipate an increase in monitoring and source control within the Eastern Subwatersheds and in the balance of the community.
Four of the 17 ORAP projects will continue beyond 2013 and will subsequently require capital funding beyond this date. These projects are:
Project 3:
CSO Storage in the Ultimate Combined Sewer Area
Project 5:
Sewer Separation Outside the Ultimate Combined Sewer Area
Project 7:
Implementation of the Wet Weather Infrastructure Management Plan
Project 11:
Implementation of Stormwater Management Retrofit Plans
The full extent of future funding commitments for Project 11 is unknown at this time because the works that define these implementation projects are still on-going. As a result, funding commitments required beyond 2013 will be detailed in a subsequent report to Committee and Council.
Both the Federal and Provincial governments have collectively provided $66 million of funding to support various ORAP projects. The following projects received partial funding through provincial and/or federal contributions:

City
Strategic Plan
Both the Ottawa River Action Plan and the
longer-term Water Environmental Strategy will reduce the impact of discharges
to the Ottawa River, and will assist in fulfilling the goals of Ottawa 20/20
and the City’s Environmental Strategy for protection of the water
environment. Combined, Projects 1, 3,
and 5 will allow the City to achieve full compliance with MOE Procedure
F-5-5, and significantly reduce the City’s discharge of E coli to the
Ottawa River.

Table A: ORAP
Project and Financial Status
[1] The Ontario Ministry of the Environment has accepted 1980 as having “average year” wet weather patterns for engineering design purposes. Overflows will continue to occur in years with more severe wet weather than what occurred in 1980. For example, in recent years, a system designed to the proposed service level would have experienced on average two (2) overflows per year. The existing system averages over thirty (30) overflows/year.
