Septic Permit Applications

Designing and building an onsite sewage system (OSS) on your property can be a complex process. It is encouraged that you hire a licensed professional who will evaluate your site, design a system, and complete the permit application process with our office. Northeast Tri County Health District (NETCHD) permits on-site sewage systems with design flows of less than 3,500 gallons per day.

Septic Permit Process

  1. Submit your completed application, ensuring all required information and documents are included. If you hired a licensed professional this may be completed by them. If you are submitting an online application, an invoice will be generated and emailed to you with a link to the payment portal.
  2. An Environmental Health Specialist will review the application to verify all required information has been submitted. An application will be considered complete when the site analysis approval is received from the county planning department and test holes are ready for inspection. 
  3. An Environmental Health Specialist will conduct an evaluation of the site and test holes. The soil evaluation report and minimum design requirements will be provided to the primary contact listed on the application. 
  4. Submit your sewage system design. The sewage system design must be developed per the Northeast Tri County Health District On-Site Sewage Regulations to meet the soil and site conditions of the property proposed for development.
  5. An Environmental Health Specialist will review your sewage system design. If the design does not meet requirements, a design review sheet listing the deficiencies will be provided. If the design is approved, an installation permit will be issued. Permits are valid one year from the date of issuance. 
  6. Installation of the on-site sewage system may begin when the permit is received by the primary contact and provided to the sewage system installer. Upon completion of the on-site sewage system installation and before the system is covered, the Health District must be notified that the system is ready for inspection. A minimum 48-hour notice is required to schedule a final inspection.
  7. An Environmental Health Specialist will conduct an inspection of the septic system to ensure the system was installed per the approved septic system design and on-site sewage regulations. If the septic system installation is not approved, a list of deficiencies will be provided. When all deficiencies are corrected, a reinspection will be required. When the septic system installation is approved, the system may be covered and the final permit will be issued.
