About Our Presentation

Rancho California Water District (Rancho Water) in Temecula, California has been studying options for a groundwater injection indirect potable reuse (IPR) project to provide a locally controlled, drought-resistant water supply that decreases salt loading to the groundwater basin.

The largest hurdle to project implementation for this inland water agency is the disposal of reverse osmosis (RO) concentrate.

This project used economic and non-economic criteria to demonstrate how Rancho Water could use high recovery RO and brine ponds with an enhanced evaporation technology to implement a larger IPR project than originally anticipated. This helped them improve water supply resiliency despite no access to a brine line or ocean outfall for RO concentrate disposal.

Plan to join us May 18 for this informative, timely discussion of one of IPR’s more restrictive issues. This presentation will provide both insight into how seemingly intractable problems were resolved, as well as understanding of how future issues may be addressed. Make your reservation today!
