On-Site Sewage Facilities

Introduction

On-Site Sewage Facilities (OSSF) are wastewater systems designed to treat and dispose of effluent on the same property that produces the wastewater. They are typically used in rural locations where public sewers are not available. Most on-site wastewater treatment systems are of the conventional type, consisting of a septic tank and a subsurface wastewater infiltration system (drain field); however, some soil types such as clay are inadequate for the proper absorption and treatment of wastewater. There are also other factors such as small lot size that can preclude installing a conventional system. For situations where a conventional system is unsuitable, there are aerobic systems. While a conventional system relies on soil absorption and natural processes in the environment to treat wastewater, an aerobic system treats the wastewater before it is released into the environment. An aerobic system is usually attached to a sprinkler system to dispose of the treated wastewater.

The Permitting and Licensing Process

The permitting and licensing process has several steps:

  • A site evaluation must be performed to determine if the property is suitable for a conventional system or if an aerobic system will be required. (A list of qualified site evaluators and designers is available here.)
  • A site design must then be drafted by a registered sanitarian or professional engineer, and submitted to ANRA for approval.
  • If an aerobic system is required, two copies of the affidavit to the public must be completed & notarized. One should be filed with the County Clerk of the county in which the property is located and the other should be filed with ANRA. They must have volume and page printed on the front.
  • If an aerobic system is required, you will need to read, sign and date the aerobic treatment systems information sheet.
  • An application must be submitted to ANRA along with applicable fees and copies of all forms such as the site evaluation, site design, affidavit to the public, aerobic treatment systems information sheet, etc.

When these steps have been completed, a permit to construct will be issued by ANRA. The homeowner will then be ready to either get bids from licensed installers and/or begin construction. ANRA will require the installer to contact our office for a closing inspection.

Once the system is installed and ANRA has performed an inspection, a license to operate an On-Site Sewage Facility will be issued, and will be kept on file at ANRA.
