Outfall 5

Storm water runoff from the upper Former Sodium Disposal Facility (FSDF -1) is monitored at Outfall 005. This water flows towards the Arroyo Simi. Stormwater flows at Outfall 005 is estimated to be 0.0007 million gallons per day for a 1 year, 24 hour storm event.

An advanced pump and treat system is in place at this location in which storm water is collected in a retention basin and pumped through a two stage system using sand and activated carbon filters. The treated storm water is then returned to the drainage channel for release.
