In the event that IRWD does not have sufficient recycled water supplies to meet customer demands, IRWD can supplement the recycled water system with untreated imported water. This water supply is introduced into the system via Irvine Lake and conveyed through IRWD’s Irvine Lake Pipeline. IRWD can also supplement its recycled water system with non-potable groundwater pumped from the Basin. IRWD coordinates with numerous agencies for the collection, treatment, and sale of recycled water. Table 6-3A indicates the agencies IRWD coordinates with for delivery of its excess sewage or recycled water and the role those agencies fulfill.
