4 apr 1799 anni - Watering Committee - Benjamin Latrobe - Steam engines pump water from schuylkill to water supply tanks

Descrizione:

Following a series of yellow fever epidemics in the late 18th century (which was at the time thought to be caused by unclean water or by rotting matter in the streets) city leaders appointed a "Watering Committee". The initial water system was designed by Benjamin Latrobe and accepted by the committee in 1799. His system utilized two steam engines (in series) to pump water from the Schuylkill River, into the city, then into two wooden tanks that held a total of just 57,000 US gallons (220,000 l). From the wooden tanks, the water was gravity fed into a series of wooden water mains. The system was plagued with problems. If either of the steam engines failed, the water supply to the city was cut off.[3
