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

It is time to renew your County registration information for 2023. If you are an OWTS installer or cleaner, you may be eligible to waive your 2023 license fee. You can access the registration form and exam if it is required based on the services you offer. Any installer that is unlicensed will need to get licensed before an installed system is permitted.  

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, 2023

New to Delta County or Planning to Develop a Property?

Get Development Permit Information to help you get things done in the right order. 

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.
