Abstract: A water use management system may be installed in a setting that contains a primary infrastructure for water use to provide an alternate, modular infrastructure for water use. Fresh water used at various points of use, such as a shower or sink, may be diverted into the modular infrastructure prior to draining into the primary infrastructure. Once diverted, the precedent use water is received at a reservoir system where it is treated for a subsequent use. Treatment may include filtration and/or chemical treatment, and may be based upon sensor feedback from the reservoir system. Once treated, the water is ready for subsequent use and may flow from the reservoir system, via the modular infrastructure, to a subsequent point of use, such as a toilet.
