NWRI White Paper: Regulatory Aspects Of Direct Potable Reuse In California

Prepared by James Crook, Ph.D., P.E., Environmental Engineering Consultant

California's water supplies are derived from a variety of sources, including local and imported surface water, groundwater, desalinated seawater, and recycled water. Water resources are becoming limited due to population increases, droughts, and reductions in imported water allocations. Furthermore, global climate change may exacerbate the problem in the future. Water recycling for nonpotable and indirect potable applications has played an integral role in helping to meet the state's water demands. California's water needs will continue to increase in future years, and new sources of supply are needed to satisfy future water demands.
