Mandatory upgrades to Orillia’s Wastewater Treatment Centre (WWTC) will start this year following the construction contract being awarded to ASCO Construction Ltd. by City Council at its meeting on Oct. 24.

An overall budget of $14.5 million has been established for the project, which is $1 million less than the initial project cost estimates of $15.5 million.

As required by the Lake Simcoe Protection Act, new compliance limits for phosphorus entering Lake Simcoe came into effect in June 2015. Tertiary treatment and process optimization at the WWTC are required to ensure the City’s annual average of phosphorus can be achieved with consistency under increased flow and higher total phosphorus concentrations.                         

“Council is very pleased to see a tender for a project of this magnitude come in under budget,” said Mayor Steve Clarke. “The upgrades to the City’s WWTC are necessary to achieve the stringent phosphorus limits set by provincial legislation and are therefore not an option. Although the City has been planning for this project for quite some time, we are depending on funding support from upper levels of government to see the project through to completion.”

Through the Clean Water and Wastewater Fund (CWWF), the City is eligible to receive a maximum federal allocation of $1,499,764 and a maximum provincial allocation of $749,882 pending a successful application process. The City appears to be eligible for the full allocation amount and all project costs exceeding the funding limit must be paid by the City. CWWF funding will not be available until January 2017 at the earliest.

Of the nine pre-qualified general contractors, ASCO Construction Ltd. came in with the lowest bid and demonstrated ability to complete the project. Substantial completion of the project is estimated at 16 to 17 months from the start of construction.

The project involves design and construction of a new cloth media tertiary filtration process, complete with a hydraulic lift station, cloth media filters and buildings to house the individual processes. Appurtenances associated with these processes include: chemical dosing system, HVAC systems, piping, electrical, controls and instrumentation ­­equipment to facilitate phosphorus removal. The WWTC upgrade will include the retrofit of the aeration process equipment, as well as the construction of a new blower building for optimization of the WWTC processes, including automation, energy efficiency and ammonia nitrogen removal.
