Sewer System Management Plan
The Sewer System Management Plan (SSMP) implementation is integrated into our overall operation and maintenance program which is predicated on complying with the 11 elements of the SSMP with the goal of minimizing sewer overflows. The primary measure of the effectiveness of the SSMP is sewer overflow performance, which include:
- Spills Impacting Surface Waters: Number of Spills and Spill Volume Reaching Surface Waters
- Spills Impacting Surface Waters: Number of Spills and Spill Volume Reaching Surface Waters
- High-Volume Spill Events: Number of High-Volume Spill Events and associated spill Volume
