Description Our FREE Above Ground Irrigation 780 USG Design Roof The above ground irrigation system will be harvesting rain from one building with one roof. Gutter, Downpipes, and Conveyance Piping The gutters, downpipes, and conveyance piping are sized based on specifications from the designs. Pre-Filter The system will require one (1) pre-filter. These pre-filters operate as both a first flush diverter and prefilter, with a filter mesh size of 320 microns. The full cross-section (pipe diameter) of the rainwater drainage system remains continuously open, and there are no reductions in the cross-section of this appliance in which dirt or water can collect. Rainwater Tank / Cistern This above ground irrigation system will provide a total of 780 USG of rainwater storage, with a total of one (1) above ground tank(s), made of polyethylene. Each tank is 780 USG. The rainwater tank is designed to provide safe storage of rainwater, which improves water quality because of its design and function. The calming inlet prevents agitation of settled fine dust, the skimming overflow removes floating particles, and the floating filter ensures water is drawn into the pump from approximately 150 mm (6.0″) below the surface of the water. Water Pumping Cleanflo determined the water demand to be 8 GPM @ 60 PSI. This will be pumped by a multi-stage booster pump. Water Quality and Treatment Cleanflo designed this system to produce water that is safe for CSA B805 R4 uses, namely irrigation.
