Mesmer Low-Flow Diversion Project CWE Project Location: Culver City, California Project Start Date: 2 January 2018 Project Completion: 1 September 2023 Project Team: City of Culver City, CWE, Beador Construction Company, Inc., Terracon Consultants, Inc Project Accreditations: LEED (in progress) Project Summary: Culver City is implementing the Mesmer Low Flow Diversion (LFD) Project as a way to address the Ballona Creek Bacteria Total Maximum Daily Load (TMDLs) for dry-weather flows and identified in the associated Time Schedule Order(TSO). The goal of the project is to comply with the final Water Quality Based Effluent Limitations during dry-weather flows as specified by the Ballona Creek Bacteria TMDL. The Ballona Creek Watershed members include the Cities of Beverly Hills, Cul- ver City, Inglewood, Los Angeles, and Los Angeles County Public Works. Impact: The project’s community and environmental impacts are improv- ing water quality and diverting dry-weather flows to the Hyperion Water Reclamation Plant. Sewer diversions effectively remove pollutants from the flows diverted to the sanitary sewer system and undergo advanced treat - ment to be used for recycled water. In areas like this, where infiltration is not feasible, sewer diversions provide a great opportunity to achieve similar benefits of improved water quality and enhanced water supply.
