Wastewater Treatment Plant Optimization Project
Project Description
The Village of Nakusp is moving forward with upgrades to the Wastewater Treatment Plant (WWTP) as part of the “Sewage Treatment System Action Plan,” developed by 9dot Engineering in 2015.
These improvements target key areas such as treatment operations, effluent quality, and sludge management.
The goal is to bring the system into compliance with Ministry of Environment discharge standards and improve overall performance.
DAF Plant Improvements Capital Project
Project Description
The Dissolved Air Flotation (DAF) plant treats wastewater before it’s released into Arrow Lake. It removes suspended solids after the wastewater leaves the treatment lagoons.
Village Operators have identified that the plant’s existing “scraper” mechanism—used to remove floating solids—is outdated and less efficient than current models.
An upgraded scraper is available from the original manufacturer and can be retrofitted into the existing system without a full replacement.
This upgrade is scheduled to improve plant performance and help maintain water quality standards.
The DAF Plant Improvements capital project is currently delayed until further notice.

Lift Station Backup Pump Capital Project
Project Description
The Village lift station moves wastewater from low to high ground so it can reach the treatment plant. It uses three pumps that rotate operation and are managed by a central control panel. A backup generator supports the system during power outages.
However, if the control panel fails or there’s a major blockage, the station could shut down entirely—risking sewage overflow into Arrow Lake.
To prevent this, the Village is purchasing a trailer-mounted, diesel-powered backup pump. This unit can operate independently and will ensure continued wastewater flow during emergencies.
