Indirect Potable Reuse

Indirect Potable Reuse (IPR) is the augmentation of a drinking water source with reclaimed water.  Cases in which the discharge of treated wastewater into a surface water by one entity impacts the downstream drinking water source of another entity are classified as “de facto” reuse.  When faced with the scenario of IPR or de facto reuse, integrating existing permitting processes is necessary.

IPR Guidance Document

An IPR Guidance Document has been developed to (1) help applicants navigate through the regulatory complexity of a potential IPR project, (2) help the appropriate programs within EPD coordinate with each other, and (3) streamline the regulatory process. This guidance is based on existing laws and regulations and provides a framework to shepherd applicants for new or modified drinking water, surface water withdrawal, and wastewater discharge permits through existing permitting processes if the request may affect an existing or currently proposed facility.
