Fairmount Water Works
Centerpiece of Philadelphia's water system, 1815-1909. The neoclassical buildings, designed by Frederick Graff and Frederic Graff, Jr., concealed huge machines that pumped Schuylkill River water to a reservoir above, whence it flowed to the city. Power was originally supplied by Oliver Evans' high-pressure steam engine, the largest of its day. After 1821 the pumps were driven by breast wheels; after 1851, by turbines.
