Why is the Waterloo WWTP being upgraded?
The current capacity of the Waterloo WWTP is sufficient and is not being increased. The purpose of the proposed plant upgrades is to meet wastewater treatment needs for the City of Waterloo until approximately 2025 when additional plant upgrades will be constructed. The proposed plant upgrades to the Waterloo WWTP will improve effluent quality to meet new criteria for discharge to the Grand River, maximize reliability by replacing aging equipment, dewater biosolids generated at the plant to reduce volume as recommended in the Biosolids Master Plan, replace and upgrade the standby power system and reduce odours generated by the treatment processes by installing odour control units for the new headworks and biosolids buildings.
What works are included for the 2009-2012 plant upgrades at the Waterloo WWTP?
The Waterloo WWTP Upgrade project includes the construction of several facilities within the existing site and replacing aging equipment to ensure reliable treatment into the future. The current capacity of the plant is sufficient and is not being increased. The proposed 2009-2012 plant upgrades will meet wastewater treatment needs until approximately 2025 when additional plant upgrades will be constructed. The following processes and facilities at the plant will be improved during the 2009-2012 plant upgrades at the Waterloo WWTP:
- Preliminary treatment and pumping;
- Primary treatment;
- Secondary treatment;
- Biosolids management and odour control;
- Administration building; and,
- Standby power facilities (pending approval of Schedule ‘B’ Class EA).
Related site works include modifications to existing plant piping and electrical servicing, instrumentation and control improvements.
Why is standby power replacement and upgrade at the Waterloo WWTP being considered?
The existing standby power system at the Waterloo WWTP was installed in 1978 and is reaching the end of its service life. The existing standby power system does not meet current MOE and Regional power standby policies and only provides sufficient emergency power for the high lift pumping station and chlorination.
How much will the Waterloo WWTP Upgrade project cost and how is it funded?
The estimated total project construction cost of the Waterloo WWTP Upgrade project is $118,000,000, which includes the cost of all plant upgrades, standby power replacement and upgrade, and engineering costs. Funding for the project will be paid through revenues from Regional wastewater user rates and Regional development charges.
When will construction start and how long will it last?
Construction within the existing Waterloo WWTP site is scheduled to start in September 2009 and it is expected that the plant upgrades will be fully completed by the end of 2012. The first construction contract will include construction of an ultraviolet disinfection building, electrical building and an administration building. Construction work for this contract is planned to commence in 2009 and be completed in 2010. The second construction contract will focus on preliminary treatment and biosolids handling while the third construction contract will deal with primary and secondary treatment and digestion. The second and third construction contracts are both scheduled to commence in 2010 and be completed in 2012.
