Is Indirect Potable Reuse being considered to enhance supplies?
Yes. Indirect potable reuse (IPR) is the blending of advanced-treated recycled or reclaimed water into a natural water source, such as a groundwater basin or surface water reservoir. After the water blends for a period of time, the water is then recovered, treated through conventional methods and then sent into the delivery system. Several local agencies in San Diego County are exploring IPR projects to enhance local supplies, and the Water Authority supports supply projects backed by local agencies.
