Interested in lowering water resource costs, wastewater costs, and being able to use water during periods of restricted use? If so, consider installing a greywater system. Greywater systems are plumbing systems that recycle wastewater collected from washing fixtures such as showers, tubs, and sinks. The wastewater is filtered so that it is able to be used in non-potable (i.e., do not drink it!) applications such as irrigation and flushing a toilet.
