Sludge wastewater Treatment Facility – Eastern Passage

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.
