Sewer Smoke Testing

Project Description: This is a preventative maintenance program that identifies locations where stormwater might enter into the sewer collection system. A non-toxic smoke is injected into the sewer pipe system and emerges into atmosphere at pipe defects and unsealed lateral connections.  In FY 2021‐2022, staff will focus on testing approximately 48,547linear feet throughout the City. 

Stormwater inflow and infiltration into the sewer collection system increases loading at the treatment plant and can cause sanitary sewer overflows. Defects identified by this program are scheduled for immediate repair. 

Total Flow, Inc. will be working with the City of Half Moon Bay to scope out the deficiencies.

Project Status: Smoke Testing is about to start on September 16th!

Funding Source(s): CIP Sewer Maintenance Program Fund
