H. Rept. 116-667: Water Recycling Investment and Improvement Act, Report Together with Dissenting Views, To Accompany H.R. 1162, Including Cost Estimate of the Congressional Budget Office, December 18, 2020 [open pdf - 570KB]
From the Document: "The purpose of H.R. 1162 is to establish a grant program for the funding of water recycling and reuse projects. [...] Water recycling and reuse projects recover and treat wastewater and impaired ground and surface water to repurpose it for a new intended use. In regions frequently affected by drought, water recycling and reuse projects can provide new, virtually drought-proof local water supplies for a variety of uses. The arid western states, and California in particular, have significantly increased recycled water use in recent years."
