EPA Tools and Resources Webinar: ?Non-Potable Water Reuse

Garland, J. EPA Tools and Resources Webinar: ?Non-Potable Water Reuse. EPA Tools and Resources Webinar: Water Reuse, webinar, October 17, 2018.
Impact/Purpose:
Increasing pressures on water resources have led to both greater water scarcity and more widespread de facto reuse of wastewater as discharges become an increasing proportion of drinking water supplies. In response, many communities have initiated or are developing centralized systems for planned water reuse. Smaller scale systems at the building or district scale are also increasingly used across the country to recycle various types of locally collected water (e.g., wastewater, source separated graywater, stormwater, rainwater) for non-potable purposes. US EPA’s Office of Research and Development (ORD) is collaborating with states and utilities who identified two key issues limiting adoption of these onsite non-potable water systems (ONWS): 1) definition of treatment requirements for safe reuse, and 2) development of standard approaches for monitoring performance. The National Blue Ribbon Commission for ONWS is a coalition of state and local groups established to advance best management practices to support the use of ONWS. ORD science results have been directly incorporated into the Commission’s guidebook for developing and implementing regulations for ONWS, and this presentation will summarize the work to date and the ongoing collaboration.
Description:
We have an opportunity before us. We can think about our new buildings can as water resources. By designing our buildings to collect and treat water generated on-site, can be and reused for flushing our toilets and irrigating our landscaping. Several water sources are generated with-in a building including: rainwater, stormwater, graywater, blackwater and foundation drainage.
