Onsite Wastewater Treatment Program (Oregon DEQ)

Permits are required for the new construction, alteration, repair or replacement of septic system components. In addition, changing the structure which is served by the septic system may require approval to continue use of the system. A report on the existing system is offered for those interested in lending or buying as specified in sales and loan documents. Records of permits have been kept since 1974 and are available to assist with finding septic locations. Consultations regarding septic system design and maintenance are also available. Inspections of septic pumper trucks are performed as required by DEQ for licensing. Complaints are investigated.
