Outfall 004 SRE

Outfall 4

Storm water runoff from the Sodium Reactor Experiment (SRE) is monitored at Outfall 004. This water flows towards the Arroyo Simi. Stormwater flows at Outfall 004 are estimated to be 0.19 million gallons per day for a 1 year, 24 hour storm event.

Extensive structural controls are in place to manage sediment run-off and improve water quality from this watershed. This includes a gravity fed three stage filter composed of sand, granular activated carbon (GAC), and zeolite.
