American Water Works, with a history dating back to 1886, is a water and wastewater utility operating across the United States. Through regulated subsidiaries it supplies drinking water, wastewater and related services to roughly 14 million people in 24 states, and employs about 7,000 people. It describes itself as the biggest and most geographically varied investor-owned water and wastewater supplier in the country, measured by operating revenues and population served.
Most activity sits in one reportable segment, the Regulated Businesses, which serves 3.6 million active customers—residential, commercial, industrial, fire service, public authorities and other utilities buying in bulk. Revenue comes mainly from metered water charges and wastewater fees billed under rates approved by state public utility commissions. A separate "Other" grouping includes the Military Services Group, which runs water and wastewater systems on 18 military installations under 50-year contracts with the US government, plus a municipal operating contract.
A holding company incorporated in Delaware in 1936, it is headquartered in Camden, New Jersey; its largest states by revenue are Pennsylvania, New Jersey, Missouri, Illinois and California.
