Sustainable Water Infrastructure Project

The City of Santa Monica Sustainable Water Infrastructure Project (SWIP) consists of three integral project elements:

  • Element 1: Brackish/Saline Impaired Groundwater Treatment and Reuse
  • Element 2: Recycled Municipal Wastewater Treatment and Conjunctive Reuse
  • Element 3: Stormwater Harvesting, Treatment, and Reuse

Together these elements will provide for advance treatment and reuse of brackish/saline- impaired groundwater, recycled municipal wastewater, and stormwater runoff. Tangible benefits of the SWIP include the following:

  • Harvest up to 4.5 million gallons (MG) of stormwater from any single storm event for treatment and permitted reuse
  • Improve beach and bay water quality through the reduction of stormwater discharges
  • Comply with State Municipal Separate Storm Sewer System (MS4) and Enhanced Watershed Management Plan (EWMP) stormwater nonpoint source pollution control measures for Santa Monica Bay
  • Recycle 1.0 million gallons per day (MGD) of municipal wastewater for permitted reuse, including future indirect potable reuse via aquifer recharge
  • Treat up to 0.5 MGD of stormwater and/or brackish-saline-impaired groundwater for permitted beneficial reuse
  • Conserve over 1,680 acre-feet per year (AFY) (547.4 MG) of groundwater or imported water
  • Reduce energy and greenhouse gas (GHG) emissions associated with the production and transport of imported water
  • The purpose of the SWIP is to contribute to existing programs and plans aimed toward achieving water supply sustainability.
