3. Water is Supplied via Two Wooden Water Tower on the Roof
No matter how much building technology progresses, one of the mainstays for water delivery remains the wooden water tower. 3 WTC is no exception, with two water towers on its roof! The street water mains can generally push water about 60 feet up (or about six floors) from the ground. At 3 WTC, like in other tall buildings, an additional water pump system further sends water to the top, in this case, from a mechanical room on the 18th floor.
