Maple Reinders undertook the Design-Build – as well as short-term operations for a 1-year period – of a new conventional activated sludge wastewater treatment facility. The facility contained screen and grit removal facilities, primary clarifiers, aeration, secondary clarifiers and UV disinfection, as well as a waste activated sludge thickening system, a sludge dewatering system using centrifuges, and a biofilter system that treats the process and building exhaust air. The plant was designed for low energy gravity flow treatment process and to protect the surrounding community from direct spills.
One of the more unusual constraints to the site, which is adjacent to Department of National Defence lands on the waterfront, was a buried steel ship hull on the property, potentially containing hazardous materials. Maple Reinders determined that no hazardous materials existed and prepared a site layout that eliminated interference with the buried steel hull.
The Port Granby WWTP, part of the larger Port Hope Area Initiative (PHAI) group of projects, is the only plant of its kind in Canada, providing a safe and long-term management solution for historic low-level radioactive waste and marginally contaminated soil in the Municipalities of Port Hope and Clarington.
The City of Vernon required a major replacement and expansion to its Water Reclamation Plant so Maple Reinders answered the call with the construction of a new 27 ML/day Biological Nutrient Removal (BNR) plant on the site of the existing plant.
