This project included upgrades to an existing lagoon, its anaerobic and facultative cells, the construction of a new storage cell, the installation of a treated wastewater irrigation system, a sanitary trunk main replacement with one manhole. Significant site dewatering and care of water was required. There was installation of 3270m of 300mm HDPE DR13.5 (trench and bore), pressure tested to 160 PSI and three crossings including a bore under the TransCanada highway #1, Range Road 182 (170m bore), and EID ditch (40m bore).
We stripped and placed 215,000m3 of topsoil, with common, borrow, and waste excavation; installation of 49,500m2 of LLDPE liner.
The project was completed in 2022.
