Sewer Prioritization Report Available

January 20, 2024

The City of Meridian and its consultants just wrapped up an approach for prioritizing the assessment, analysis, and rehabilitation of the city’s existing Wastewater Collection and Treatment System (WCTS).

According to David M. Ruhl, program manager for Waggoner Engineering, this WCTS includes all the sewer pump stations, sewer piping, and wastewater treatment plants. This report proposes a multi-year plan to facilitate the identification, prioritization, and rehabilitation of structural defects, capacity issues, and problems that allow infiltration and inflow (I/I) into the WCTS. The excessive I/I is characteristic of an old city’s collection system and must be addressed to eliminate Sanitary Sewer Overflows (SSOs) and void the current Sewer Consent Decree.

This Sewer Basin Prioritization Report provides the results and conclusions of the severity of I/I issues within the WCTS and prioritizes sewer basins into three sewer groups, with Sewer Group 1 being the most critical. Sewer Groups 1 and 2 generally include areas with the highest impact to rain-dependent infiltration and inflow, while Sewer Group 3 contains areas that will be addressed under the applicable sections of the City’s Capacity, Management, Operations, and Maintenance (CMOM) Programs.
