Wastewater Treatment Plant

The City of Red Deer Wastewater Treatment Plant collects the wastewater that comes from the residential, commercial and industrial wastewater collection system. The WWTP for 2007 treated on an average day almost 43,000 m3 (equivalent to 43 million litres) and is designed to treat an average daily flow of 35,000 m3. The raw wastewater flows through the wastewater collection system by gravity force, combined with lift stations that pump the wastewater into the WWTP for treatment prior to discharge into the Red Deer River. 

Treatment Plant
The raw wastewater goes through different cycles and/or processes before it is released as clean water. Treated wastewater leaves the plant area through a channel before being released into the Red Deer River. This creates better water quality for downstream users and prevents disease in human and aquatic life. The yearly average of wastewater recycled back to the Red Deer River is approximately 1,092,075 cubic metres.
