The SMURRF (Santa Monica Urban Runoff Recycling Facility) is an innovative facility built in Santa Monica, CA that was designed to handle "dry weather runoff." Dry weathe runoff includes runoff from irrigation, pools, construction sites and car washing instead of stormwater runoff. However, when capable the SMURRF system can handle a varied amount of storm water runoff.
"The SMURRFF is capable of handling in upwards of 500,000 gallons per day (gpd) of urban runoff generated in parts of the cities of Santa Monica and Los Angeles. The runoff water is diverted from the City's two main storm drains (Pier, Pico-Kenter) into the SMURRF and treated to remove pollutants such as trash, sediment, oil, grease, and pathogens. Treatment processes include:
- Coarse and fine screening to remove trash and debris
- Dissolved Air Flotation, DAF to remove oil and grease
- Degritting systems to remove sand and grit
- Micro-filtration to remove turbidity
- Ultra-violet (UV) radiation to kill pathogens
Once treated, the water is safe for all landscape irrigation and dual-plumbed systems (buildings plumbed to accept recycled water for the flushing of toilets) as prescribed by the California Department of Health Services. The treated water meets all of California's Title 22 requirements (the level of treatment that the runoff water must meet)."
