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 /> � a <br /> f <br /> Exhibits: Example concrete vaultstorage tank(Storm Trap). <br /> r a <br /> Exhibit 3: Example underground fiberglass storage tanks(Xerxes). <br />
