The City has maintained a municipal water system since 1872. Rock Island's source of water is the Mississippi River. An average of 5 million gallons are pumped daily to the Water Treatment Plant at 2215 16th Avenue for processing. A large ground storage facility and six elevated towers supply the 220 miles of water mains and 2,000 fire hydrants that deliver drinking water and provide fire protection throughout the City.
