I had some questions about the level of salt in treated water coming from the Tapia water reclamation facility, for staff members of the Las Virgenes/Triuno Sanitation partnership.  What I found was that the level of dissolved salt in the water discharged to Malibu Creek by the partnership, is much lower than what occurs in the creek naturally.

Here is the LVMWD/TSD staff response:

“Recycled water that is produced by the JPA’s Tapia Water Reclamation Facility (TWRF) has about 775 mg/L of total dissolved solids (TDS or “salt”).  The salt make-up of the recycled water largely mirrors that of the District’s source water, which is exclusively imported water from the Sacramento-San Joaquin Bay Delta (State Water Project) purchased from Metropolitan Water District.  For comparison purposes, TDS levels for water in Malibu Creek range from about 1,100 mg/L to over 3,000 mg/L.  The creek’s TDS is comprised largely of sulfates from the Monterey Formation, a natural geologic formation present in the watershed.”
