What Is a Sanitary Sewer Overflow?

A sanitary sewer overflow, or SSO, is a release of untreated or partly treated wastewater from a sanitary sewer before it reaches the treatment plant. Some places use different terms. Under some permits, a wastewater backup into a building can also count.

Signs include wastewater coming out of a wet well, manhole, cleanout, pipe, or building drain. Stains, debris, wet ground, odor, customer calls, and level history can also point to an event.

Protect people first. Follow plant procedures for site control, keeping people away from wastewater, traffic, sampling, cleanup, and working with public health or other agencies.

Do not wait to know every detail before telling your supervisor. Early notice lets the reporting and response decisions start on time.

Key point: A suspected overflow needs fast protection, notification, investigation, control, and records.
