Stormwater Non-Potable Beneficial Uses and Effects on Urban Infrastructure

This project shows that lessons learned from international stormwater beneficial use projects cover a range of conditions that can be found in the U.S. The research examined case studies from developing countries in arid and wet climates, from developed countries in areas where future water conservation is necessary to support continued growth, and from developed countries where sustainable use of natural resources is a priority. Water quality degradation associated with different storage options was reviewed, along with different water treatment options to meet the needed “finished” water quality before use. The report provides guidance on how to determine the amount of supplemental landscape irrigation needed from stored stormwater, and how to calculate needed tankage volumes for locations in the U.S. The report calculates the beneficial use opportunities of stormwater, especially landscaping irrigation, in different areas of the country, along with continuous modeling results for the development of production functions for tankage volume alternatives.
