Simi Valley to explore an alternative source for water

By Debra Tash

At their August 26th meeting the Simi Valley City Council heard a presentation on the Bell Ranch Desalter Project.  At present Simi Valley’s Waterworks District 8 uses 23,000 acre feet (a foot deep of water covering an acre of ground) per year.  It buys the majority of its supply through Calleguas Municipal Water District.  Being imported that supply is becoming more costly due to continued shortages.  Simi is seeking another source.

For over three decades the City has used de-watering wells on the west end of town to pump brackish water into the Arroyo Simi, along with effluent from the sewage treatment plant.   The water travels westerly along the arroyo into the Santa Rosa Valley and eventually sinks. Over the years it has created an underground water mound.  Desal Water Company LLC,  a limited partnership, plans on building the Bell Ranch Desalter in Somis.  It has yet to do a hydrology study on the mound but they believe there is a 20 years supply that can be tapped into and treated. 

Simi is interested in buying the water after it’s been put through a reverse osmosis process at the proposed Bell Ranch DeSalter.   

The Council voted to authorize the District Manager to execute a non-binding Letter of Interest (LOI) to the Desal Water Company, LLC.  This may be the first step in finding another source of water for the citizens of Simi Valley.
