There has always been a good reason to criticize the city’s sewer system in recent years, considering the volume of diluted sewage that has spilled into the Ottawa River from aging infrastructure.
But one organization is celebrating the city’s achievements in trying to fix the problem.
The Consulting Engineers of Ontario, during its annual gala last Saturday, recognized a city contractor for the design of the real time control system on the combined sewers.
Here’s the description of the award:
Award of Merit – Environment
Stantec Consulting Ltd.
Real Time Control Implementation and Flow Regulator Upgrade Project
Client/Owner: City of OttawaStantec completed the design and integration of a Real Time Control system for the automated operation of Ottawa’s combined sanitary and stormwater system. The system minimizes combined sewer overflows by dynamically adjusting multiple flow regulating chambers and has led to a 60 per cent reduction in overflow volumes to the Ottawa River.
There is still sewage spilling into the river on very rainy days, but it does seem like the number of overflows has decreased. It felt like we were writing about spills every time there was a sprinkle a few years ago.
Another Ottawa project received an award at the gala, too. The association’s PR firm says the Museum of Nature’s Victoria Memorial Museum Building was saved from sinking, thanks to Halsall Associates.”The firm also built a new glass tower that gave the heritage building new life. The Queen’s Lantern, the glass tower that reproduces the majesty the building lost when its front tower had to be demolished. Halsall was given an award of engineering excellence for the rehabilitation of the Victoria Memorial Museum Building.”
