How to Apply for a Septic Permit

  1. Read our document "Property Owner's Guide to getting a Septic System Permit".
  2. Download the Septic and Well Permit Application in Adobe PDF Format or pickup an application at our office located at 301 W Alder, Second Floor (Health Dept).
  3. Complete the application form and assemble the information required in 'B' below. Bring the supporting information and the application to our office. The Department will typically issue or deny permits within one week, the fee will be due when picking up the permit. (see fee schedule for septic fees). 
  4. Effective February 18th, 2010 there is a $100 application fee for all septic permits.  The Health Code states that the application fee is nonrefundable.

    The overall fees didn't change. Instead, this allows us to collect part of the fees at the beginning of the process to cover the Department’s costs for writing septic permits. The balance of the fee (for example, $145 for a basic permit or $200 for a pressure permit) would be collected when the permit is issued.
