The Water Works raceway is a straight, dirt ditch with sloping sides constructed to deliver water from the San Antonio River to the Water Works pump house. As originally constructed, the ditch measured about 40 feet wide and 650 feet long- that’s almost 100 feet longer than The Washington Monument! The raceway was designed with a nine-foot fall that provided power to drive turbines and pumps. Water re‐entered the river at the pump house. Today the raceway is abandoned and dry, but just as large!
