Sewer
The City of Castlegar operates a community sanitary sewer collection system with two wastewater treatment plants: the South Sewage Treatment Plant (SSTP) and the North Sewage Treatment Plant (NSTP) lagoons.
The system relies on a gravity collection system made up of approximately 74 kms of pipe and 12 lift stations which gathers the sewerage and conveys it to the two treatment facilities, and eventually discharges to the Columbia River.

Liquid Waste Management Plan
The City of Castlegar is developing a Liquid Waste Management Plan to guide the City’s management of liquid waste over the next 20 years.
What is Liquid Waste?
Liquid waste is also referred to as wastewater, sewage, and stormwater runoff. Anything that is flushed down a toilet, or poured down a sink or drain, or water that falls on roads, becomes liquid waste.
South Sewage Treatment Plant (SSTP)
At the City of Castlegar’s South Sewage Treatment Plant (SSTP), wastewater first passes through the headworks (consisting of screens to remove garbage and large solids), a vortex and classifier to remove grit, and a flow measuring device.
North Sewage Treatment Plant (NSTP) – Lagoons
Wastewater from the north end of Castlegar travels over the CPR bridge and into the headworks structure at the North Sewage Treatment Plant (NSTP).
