Lead by example by conserving water use within local government operations. For example, evaluate the potential for installing rainwater collection systems for graywater uses at government facilities and investigate opportunities for graywater reuse at existing and new facilities and properties. Uses could include irrigation, cooling towers and toilet flushing. Graywater is the relatively clean wastewater from other uses, such as from washing machines, bathtubs and sinks. Reducing water use can prevent or alleviate drought impacts.
