Onsite Wastewater Management Program (Septic Systems)

Current News
  • Deschutes Groundwater Protection Project - DEQ is working with the community to protect the groundwater from nitrate contamination from traditional onsite septic wastewater treatment systems in southern Deschutes and northern Klamath counties.


  • The Onsite Program will be increasing septic system fees. The new fees will take effect January 4, 2010. The fee increase will affect counties where DEQ directly operates the septic system program. DEQ operates the program in 14 counties as shown on the map.

    In addition, applications to DEQ for new product applications, denial reviews and variance applications will be increasing statewide. DEQ’s deadline for accepting an application with the current fee is 5:00 PM, December 31, 2009. Applications received after that date will be subject to the new fee.

  • An Onsite Advisory Committee was recently assembled to review and recommend changes to DEQ with respect to the administrative rules that govern onsite wastewater treatment systems, materials, and licensing. For more information, contact Randy Trox at 541-687-7338 or by e-mail.
