View looking north from the forebay showing the race bridge at the Fairmount Water Works on the Schuylkill River. Also shows the ascending mains connected to the old mill house after the designs of Philadelphia engineer Frederick Graff, Jr. during the replacement of the house's water wheels by turbines between 1867-1872. The waterworks, originally constructed between 1812 and 1822 after the designs of Philadelphia engineer Frederick Graff, were altered and expanded until 1872.
