To protect the environment and meet local water needs. Water recycling is not a luxury but a necessity as water is a precious natural resource that is in short supply in semi-arid Southern California. There is no new water so recycled water reduces dependence on our limited water supplies helping to drouth-proof the rapidly growing Inland Empire. 100 percent of the IEUA’s recycled water is reused. Recycled water provides a safe, cost-effective and reliable supply of high quality water.
