Well Water Supply Program

Permitting Process


All wells drilled or repaired in Hamilton County are required to be permitted and drinking water wells must be sampled before being released for use. Well permits must be obtained from the Hamilton County Health Department. Applicants may receive a Well Water Permit Application from the Health Department or by downloading a copy of the permit application (PDF). The application must be accompanied with any applicable fees and a site plan, which includes the following:
  • Scaled Plans (No greater than 1 inch to 50 feet)
  • Lot dimensions including topography
  • Location of house, well, septic system or sewer (if available), or other structures

Well Samples


Once a well is drilled or repaired it must be sampled to ensure a safe drinking water supply. The Hamilton County Health Department will sample the well using the Indiana State Health Department laboratory or applicants may use a state certified laboratory for water sample analysis. For a list of Indiana Certified Drinking Water Laboratories, visit the Indiana State Health Department. This list of laboratories is merely provided as an information tool to assist individuals wanting to receive sampling information. The Hamilton County health Department does not endorse one particular laboratory. Water samples from other certified laboratories which are not listed will be accepted by the Hamilton County Health Department.

Well Chlorination


Water samples occasionally return unsatisfactory and may require additional disinfection. Well Chlorination Procedures (PDF) for drinking water supplies are available through the Hamilton County Health Department.

Abandoned Wells


Wells that are abandoned in Hamilton County also required to submit a IDNR abandonment log, which is recorded to the well permit and related parcel for future reference. The public seldom understands the need or importance of protecting our ground water supply through proper well abandonment. The Department of Natural Resources promulgated Rule 310 IAC 16-10-1 to provide guidance to the public in dealing with unused wells and proper abandonment. The Hamilton County Soil and Water Conservation District provides funding to cap wells. The application must be submitted and approved before the capping is started. Click here for details on the HCSWD well capping website.
