After Hiring a Water Well Contractor

Determine Suitable Well Location
Consult with your water well contractor to determine the most suitable location for your well. The well should be located as far as possible from any sources of contamination. The information below shows the minimum distances that the code allows a water well to be located from a source of contamination. When you place your water well at these minimal distances, you are reducing the chance of contaminating your water supply.

Minimum Separation Distances
Some minimum separation distances for water wells:
  • Septic tank - 50 feet
  • Septic Field - 75 feet
  • Septic Field Expansion Area - 75 feet
  • Body of Water - 25 feet
  • Sewer Line - Clay Pipe or Thinner Than SDR 26 - 50 feet
  • Sewer Line - SCH 40, SDR 26 or Cast Iron - 10 feet
  • Cesspool - 150 feet
  • Leaching Pit - 100 feet
  • Footing Drains - 10 feet
  • In-Ground Swimming Pool - 10 feet
  • Structures With Roof Overhang - 2 feet
Submit Application
Once the proposed location of your water well has been determined, have the water well contractor submit an application to the LCHD. The permit fees pay for a portion of the costs of Health Department personnel reviewing the application and inspecting the water well after construction.

Application Requirements
The submitted application must have the following information:
  • Lot lines and dimensions
  • House or building location
  • Location of all septic tanks, septic field or sewer (including surrounding properties)
  • Location of proposed and existing wells.
  • Proposed well location must meet the minimum separation distances to sources of contamination listed in the Illinois Water Well Construction Code (Section 920.Table C).
  • Proposed and existing water lines that convey water from the new well.
  • Provide the location of an available community water system if any or a statement that no community water system is available on your site plan.
The above information is usually provided on a septic plan layout. If the information is not available, then it must be provided on a separate sketch. To help the water well contractor fill out your water well permit application, please provide the information on the most recent plat of survey or site plan to scale, along with the Permanent Index Number (P.I.N.). The P.I.N. is located on your tax bill from the township assessor's office, and is also referred to as the tax I.D. number. You may obtain copies of the most recent plat of survey and the P.I.N. by contacting your township assessor's office.

Once the water well contractor has submitted the water well application and fee to the LCHD, the application will be reviewed and acted on within 10 to 15 working days. After the water well application has been approved, the water well contractor may start constructing the new water well.

If the application is rejected, the applicant will receive a written explanation of why the application was rejected, and the actions that need to be taken to obtain approval.
