Indirect potable reuse (IPR) and direct potable reuse (DPR) are two ways of intentionally augmenting potable water supplies with highly treated water from a water reclamation facility. IPR includes discharging from a water reclamation facility to a surface water or groundwater body for blending and subsequent treatment. DPR does not include the use of this “environmental buffer,” instead going directly from the water reclamation facility to further treatment and blending with traditional supplies. Drought and limited water resources are the main drivers, coupled with a significant maturation of the technologies needed to implement DPR safely and cost-effectively, including membrane treatment and brine management.
