The Santa Monica Urban Runoff Recycling Facility

SANTA MONICA URBAN RUNOFF RECYCLING FACILITY

The Santa Monica Urban Runoff Recycling Facility (SMURRF) treats urban runoff that would otherwise flow into the Santa Monica Bay. The facility can treat up to 500,000 gallons per day from the Pico-Kenter and Pier Storm Drains, which together account for 90 percent of the city’s total dry weather runoff. SMURFF treats runoff from excessive irrigation, spills, construction sites, pool draining, car washing, the washing down of paved areas, and some initial wet weather runoff. Runoff from these sources previously flowed directly into Santa Monica Bay through City storm drains.

The treatment process at SMURRF includes the following steps:

  • Coarse and fine screening to remove trash, plant material and debris
  • Degritting systems to remove sand and grit
  • Dissolved air flotation (DAF) to remove oil and grease
  • Microfiltration to remove turbidity
  • Ultraviolet (UV) radiation to kill pathogens.

By treating urban runoff during dry weather, the SMURRF reduces the amount of pollutants reaching Santa Monica Bay which improves water quality, benefits aquatic life and beach goers, and reduces the regions need for imported water. Additionally this treated wastewater is used for landscape and toilet flushing in Santa Monica.
