The City of Nashua Water Supply System includes three (3) active wells which draw from two (2) separate aquifers – the Jordan and Devonian, a 300,000 gallon water tower, and miles of water utility mains. Approximately 100,000 gallons of water is pumped from the wells, disinfected by chlorination, and delivered each day. Nashua takes pride in providing clean water for drinking, fire protection and industrial use. This water, per IDNR (Iowa Department of Natural Resources) requirements, is tested daily, monthly, quarterly, yearly, and periodically according to Nashua’s Water Supply Operation Permit. Water quality is the primary commitment to the citizens and industries of Nashua, along with adequate and efficient supply. The Environmental Protection Agency’s Safe Drinking Water Act provides the rules and regulations to ensure safe drinking water.
