About this detail

A complete rainwater harvesting system connects rooftop inlets to a 26,000-gallon cistern with eight-inch smoothing inlets, a thirty-inch manway, and a four-inch tank vent. The system incorporates high and low water alarm floats, a two-inch floating filter, and overflow lines draining to a storm sump pit. Treated water flows through a rainwater filtration skid, a day tank with a backup domestic water connection via a reduced pressure backflow preventer assembly, a booster pump skid, and a pressure tank supplying water closets and urinals.
