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 2020‐2021, staff will focus on testing approximately 55,864 linear 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.  

Project Status: Smoke Testing Completed!  A total of 13 collection system defects were identified including defects at 7 City sewer manholes.  The City has contracted H&R Plumbing and Drain Cleaning to make the repairs. 

Funding Source(s): CIP Sewer Maintenance Program Fund
