Each asset is routinely inspected, evaluated, and placed into a renewal and replacement program to ensure the City can provide reliable services in the future. The City completed a major "What a Relief" (once in 50 years) Sewer Rehabilitation Project in 2019.

Sanitary Sewer Overflows
A sanitary sewer spill, or "sanitary sewer overflow" ("SSO"), is typically caused by either:
- clog/backup, capacity issue, or structural failure in the City's sanitary sewer collection system, or,
- clog/backup, capacity issue, or structural failure in a privately-owned sewer lateral or system.

Raw sewage. Have you ever had it come out of your toilets, shower stalls or sinks? Though rare, some residents have experienced such unfortunate events. While the City has an aggressive maintenance program that includes cleaning and inspecting sewer mains, it is still possible that a City sewer main can plug up and lead to sewage flooding. However, by installing sewer laterals and release valves (SRV and BWV) on at-risk properties, owners can minimize their exposure to such an incident. Find out more information in this guide.
