Fiberglass tanks generally are <br /> available up to 50,000 gallons in size. A 50,000-gallon tank has dimensions of approximately 68 <br /> feet long with a 12-foot diameter. Three tanks, with space between, could fill a footprint of <br /> approximately 5,000 square feet. Concrete vaults can be sized to fit multiple footprint sizes. If a <br /> maximum active depth of water in the vault of 8' is assumed,the footprint would be approximately <br /> 2,500 square feet. <br /> —NNW ;0 <br /> Its <br /> t1b <br /> N <br /> __QL_ <br /> --mr- <br /> 9E, <br /> 16 <br /> Exhibit2: Example concrete vault storage tank(Storm Trap). <br /> 16 <br /> rg <br /> fl <br /> • <br /> 7 M*NIR <br /> -96 <br /> ir <br /> r rN <br /> _%-00 AGO'&Ok- <br /> Exhibit 3: Example underground fiberg lass storage tanks(Xerxes). <br />
