Sewer is collected through underground pipes, centralized in manholes, and flows to the lift station where it is pumped through two lines into Burns Lake lagoons. The retention length is approximately 8 days, unless there is significant extra flow due to infiltration.
Infiltration is generally caused by homes allowing their drains and sump pumps to flow into the sewer system, which is in contravention of the sewer bylaw. In addition snow runoff can infiltrate through manholes and access points which causes a significant increase to flow into the sewer lagoons during spring runoff. This results in increase costs due to the treatment process.
