The City of Andover was incorporated in 1974 and established their initial water supply facility shortly after in 1981. Today, Andover city water services over 20,000 people and comes from 8 wells, 6 of which are primary water supply wells. 5 of the primary water supply wells pump from the deeper, Tunnel City-Wonewoc aquifer and the 6th pumps from the unconsolidated, confined sand and gravel aquifer closer to the surface (although it is still over 260ft deep!).

The City of Andover began treating their water in 2002, when their Water Treatment Facility was constructed. The facility removes iron and manganese from the pumped well water before it is distributed to homes and businesses in the City.
