Why Pure Water?

Over the past several decades the Los Angeles Regional Quality Control Board (LARQCB) has increased restrictions and requirements of the recycled water (RW) the Tapia Water Reclamation Facility (Tapia), owned and operated by Las Virgenes – Triunfo Joint Powers Authority (JPA).  The District's current National Pollutant Discharge Elimination System (NPDES) permit allows discharge of excess RW from November 15 to April 15.  Today's current permit for discharge excess RW based on total maximum daily load (TMDL) would actually make it illegal to pour drinking water into the creek.

Consideration for a seasonal storage facility showed this would only reduce, not eliminate, the discharge of excess RW to Malibu Creek. While seasonal storage would provide more RW for irrigating parks, highway landscapes, golf courses, school grounds, commercial landscapes and garden areas of multi-family dwellings.  Using RW for these purposes also reduces the demand for imported water in the JPA’s service areas, conserving both water and energy.

However, a stakeholder-driven process has led to another option, the notion of Indirect Potable Reuse (IPR), now known as the Pure Water Project Las Virgenes – Triunfo. This option would take surplus recycled water and process it through an advanced treatment facility; then store it at Las Virgenes Reservoir for later use as drinking water.
