While visiting my grandson in Philadelphia I’ve had time to wonder about the water that comes through the plumbing here.
Philadelphia’s water is taken from (and returned to) the Schuylkill and Delaware Rivers. The Philadelphia Water Department cleans the water before it enters the system and after it’s been used by the city residents. The average Philadelphian uses 87 gallons of water per day. The city as a whole can treat and distribute more than 540 million gallons of water each day.
The City maintains an attractive and informative interpretive center at Fairmount Waterworks, pictured below.
