The Manassas Water Tower is a historic water storage facility at 9000 Quarry Street in Manassas, Virginia. It is a steel structure 147 feet (45 m) in height, and is typical in style for its 1914 construction date, with a steel trestle supporting a tank with a hemispherical base and conical roof. It has a capacity of 75,000 US gallons (280,000 L; 62,000 imp gal). It was built near one of the city's six water wells, and is one of six water towers in the state with a hemispherical bottom.
