The City of Commerce entered into a Supplemental Environmental Program (SEP) to reduce excessive inflow/infiltration. Developed the SEP program, and then implementing the project through construction.

Our Solution

This project was begun with an evaluation of flow monitoring and a sanitary sewer evaluation system (smoke testing) to prioritize system inflow / infiltration problems.

Additionally a TV inspection of approximately 5,300 LF of 12-18 inch sanitary sewer main was performed.

Improvements included replacement of approximately 7,887 Lf of 6” to 24” sanitary sewer lines, 26 new manholes, 50 rehabilitated manholes, and 15 point repairs.

Improvements also included a 24 inch gravity sewer inlet line and control panel replacement for the SH 11 North lift station.
