Construction/Installation Permit

Installation permits are issued for construction of new sewage disposal systems to serve new site development. A favorable Site Evaluation for the property must be completed and issued before applying for an Installation permit. An owner of a property may install their own sewage disposal system. If you intend to do so, please contact our office so we can provide you with additional information and consultation.

Existing System Evaluations

We evaluate and report on existing sewage disposal systems when needed. These reports are provided in certain circumstances such as when a piece of property is being divided or as a service to buyers, sellers, or lending institutions. When a property is being divided, evaluations are done to ensure that the sewage disposal system is entirely on the correct parcel and that adequate area remains for a replacement system in the event it is needed.

Permit Renewal, Re-instatement or Transfer

Permits expire one year after the date of issuance and may be renewed or reinstated by the original permittee. They must be renewed or reinstated within one year of the expiration date of the permit.

Permits may be transferred from the original permittee to a new property owner if the transfer is completed before the original permit expires, and no changes in the permit are needed. Otherwise, a new permit is required. A transferred permit carries the same expiration date as the original permit.

Licensed Installers

Any person (except for the property owner) involved with the installation or construction of an on-site system or involved with the grading, excavation or earth-moving work associated with an on-site system must be licensed and bonded as an Installer by the Oregon Department of Environmental Quality.

Search the Department of Environmental Quality (DEQ) database for actively licensed installers by County.

Rules and Regulations

The requirements governing the siting and construction, alteration, repair, operation, and maintenance of onsite wastewater treatment systems are established in Oregon Administrative Rules (OAR) 340-71 and 340-73 and Oregon Revised Statutes (ORS) 454 and 468B.

Maintenance of Septic Systems


Property owners are responsible for the operation and maintenance of their septic systems. A properly designed, constructed, and maintained onsite system can provide years of trouble free service. The following links may provide you with useful information on the care of your system.

Alternative Treatment Technology

If your system is an Alternative Treatment Technology or a commercial system utilizing a Sand Filter or Recirculating Gravel Filter, you are required to maintain a service contract with a Licensed Service Provider for the life of the system.

This also applies to residential systems that utilize a sand filter or pressurized distribution if the system was permitted after January 2, 2014.

Alternative Treatment Technologies are also subject to a Time of Transfer Evaluation at the time of sale.
