According to the reuse calculator, there will be <br />enough captured stormwater water in approximately <br />90% of the pumping season weeks to apply I -inch per <br />week of water over the area to be irrigated (a total of <br />454,000 gallons required). Since rainfall contributes to <br />that total, as well as stored water in that tank, the total <br />required volume per year does not translate to the size <br />of the tank required. Instead, the volume of the tank can <br />be modified to target an irrigation efficiency. <br />The storage volume could be a single concrete vault or <br />multiple fiberglass underground units. Given the size <br />of individual cisterns, plastic is not available. Fiberglass <br />tanks generally are available up to 50,000 gallons in size. <br />A 50,000-gallon tank has dimensions of approximately <br />68 feet long with a 12-foot diameter. Three tanks, with <br />space between, could fill a footprint of approximately <br />5,000 square feet. Concrete vaults can be sized to fit <br />multiple footprint sizes. <br />28 <br />
