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 />Exhibit 2: Example concrete vault storage tank (StormTrap). <br />Exhibit 3: Example underground fiberglass storage tanks (Xerxes). <br />ion 6 hairdo- <br />
