Non-potable water reuse (NPR) is the reuse of treated water for non-drinking purposes, such as toilet flushing, clothes washing, and irrigation. The Non-potable Environmental and Economic Water Reuse (NEWR) Calculator can help identify environmentally and cost effective options for onsite NPR based on user selected geography, building specifications, source water type, and end use. Follow the prompts to explore building-scale NPR opportunities in your region. NEWR is intended for screening-level analysis of buildings with 50 or more residential and/or office occupants. NEWR is not intended to provide a detailed engineering analysis.
