Would You Like to be a Septic System Installer in Delta County?

The deadline to apply for a license as a Septic System Installer has passed. Any renewal will be processed as a new license ($100.00= renewal fee + late fee). Any installer that is unlicensed will need to get licensed before an installed system is permitted. All previously licensed non-NAWT installers will need to complete the OWTS application and an exam will be required after November 2022 for all installers. This exam will cover the new regulations adopted during the summer of 2022. 

The license renewal fee is $50 per year. As allowed by the OWTS regulations, a late fee of $50 will be charged for all renewals received after January 31, 2022.

Building in a Floodplain?

All development within designated flood plains requires a permit from the Delta County Environmental Health Division prior to installing any septic system. The property owner is responsible for ensuring this determination takes place. If you think that you will be building in or near a floodplain, you can easily search for the floodplain status on the FEMAs website. Floodplain FIRM (Flood Insurance Rate Maps) are downloadable or contact Environmental Health at 874-2165 to obtain information regarding flood plain development. A flood plain application is required (fillable PDF application), and a flood plain checklist (pdf) is available for developers to guide the process. The floodplain application fee is $250.00.
