Reclaimed water can be deployed for irrigation or non-potable uses through piping systems separate from potable water called dual pipe systems (NPR). Reclaimed water can also be stored in aquifers or surface water bodies, which supply potable water systems (IPR). This project developed a decision support tool that incorporates drivers and constraints of NPR and IPR alternatives with financial, social, and environmental criteria through a Triple Bottom Line (TBL) approach to deploying reclaimed water resources. The goal of the projects is to produce a decision making tool that would facilitate informed, defensible decisions regarding capital investments for non-potable reuse (NPR) or indirect potable reuse (IPR) alternatives at municipal and regional planning levels.
