Description Our FREE Above Ground Irrigation Tank, 3600 USG – With Below Ground Surge Design This above ground irrigation tank rainwater harvesting system is designed as a secondary source of water for irrigation purposes, such as watering gardens, irrigation, etc. The system will provide water for water uses Tier: R1 – non-potable irrigation only Roof The system will be harvesting rain from one building. The roof is provided by others and should be suitable for intended use. Gutter, Downpipes, and Conveyance Piping The gutters, downpipes, and conveyance piping are sized based on specifications from the designs. The gutters, downpipe, and conveyance piping are provided by others and should be suitable for intended use. Prefilter The system will require one (1) pre-filter. This pre-filter operates 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 system will provide a total of 3600 USG of rainwater storage, with a total of three (3) above-ground tanks, made of polyethylene. Each tank is 1200 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 and Treatment System Cleanflo determined the water demand to be 8 GPM @ 60 PSI. This will be pumped by a multi-stage booster pump. The filtration will be one stage to ensure water is safe to use. Stage one is a sediment filter of 25 microns. Water Quality and Treatment Cleanflo designed this system to produce water that is safe for CSA B805 R1 uses; namely non-potable irrigation only.
