The Long Beach Municipal Urban Stormwater Treatment Project (LB-MUST) is a comprehensive and innovative regional project that will intercept and treat dry weather runoff and first-flush storm flows generated within the City of Long Beach before discharging to the Los Angeles River and Estuary. The centralized downstream advanced treatment facility has a planned capacity capable of collecting and diverting approximately 41% of the City's 12,200-acre watershed. This treatment facility will assist with the compliance with the National Pollutant Discharge Elimination System (NPDES) Permit, including Total Maximum Daily Loads (TMDLs). Treated water will be used as an alternative water supply for the irrigation of City parks and for a wetland to be constructed next to the treatment facility, which will provide additional treatment/water polishing and a recreational amenity for the nearby community. After proceeding through a rigorous independent third-party project verification process, the LB-MUST project earned Envision Platinum for sustainable infrastructure from the Institute for Sustainable Infrastructure and is poised to achieve LEED Silver.
