Sachigo Lake First Nation Wastewater Treatment Project

The Sachigo Lake First Nation has a facultative wastewater treatment lagoon which requires upgrading to meet the current and future organic and hydraulic loading from the community to design year 20. The existing lagoon cells will be combined into one primary cell, and a new storage cell will be constructed utilizing insitu and reworked soils from the site excavation. The lagoon would also require a new perimeter fence, intercell and discharge piping, a concrete spillway and rip rap stone. In addition, the wastewater collection system will be upgraded with new gravity sewer, service lines and forcemain to service new development areas, along with a new lift station. This project will also include the installation of a raw water intake pipe from the WTP into Sachigo Lake, while the existing intake pipe will be abandoned in place. The WTP backwash pipe will be connected to the gravity sewer system.

Latest update
