Indianapolis Water, which operates as Citizens Water, keeps helps slake the thirst of Hoosiers, lubricate their industries, and irrigate their farms. The regulated utility, which has served "Naptown" since 1871, distributes water to about 1 million people in central Indiana, including 13,250 customers in Hendricks County. Indianapolis Water gets its water supply from the White River, streams, and reservoirs. Former parent NiSource sold IWC Resources (the former holding company for Indianapolis Water) to the City of Indianapolis in 2002; the city has in turn signed a 20-year management contract with Veolia Water. In 2011 ownership of Indianapolis Water was transferred to public charitable trust Citizens Energy.
Citizens Energy manages Indianapolis' gas utilities. The move was made to create greater operating efficiencies.
Affiliates Harbour Water, and IW Morgan Water, which are also former subsidiaries of IWC Resources that were sold to the City of Indianapolis and are now managed by Veolia Water, supply water to surrounding areas in central Indiana.
