Latrobe also was hired to design the Center Square Water Works in Philadelphia. The Pump House, located on the common at Broad and Market Streets (now the site of Philadelphia City Hall), was designed by Latrobe in a Greek Revival style. It drew water from the Schuylkill River, a mile away, and contained two steam engines that pumped it into wooden tanks in its tower. Gravity then fed the water by wooden mains into houses and businesses. Following his work on the Philadelphia water works project, Latrobe worked as an engineer of the Chesapeake and Delaware Canal.
