How Do I Get a Septic Permit in Hinsdale County, Colorado?

Hinsdale County's Building Department says anyone installing a septic system should review the guidelines and checklist, then submit an OWTS (onsite wastewater treatment system) application. The county cites the state rule 5 CCR 1002-43 from the Colorado Department of Public Health and Environment, and points to the Silver Thread Public Health District for more information.

What does the application include?

Per the county's OWTS Permit Guidelines document: the application, the permit fee, the permit checklist and a detailed site plan. The fee listed there is $500, non-refundable, and incomplete applications will not be reviewed. Sites beyond a ten-mile radius of the County Courthouse incur a mileage charge. Fees can change, so confirm with the department.

What about soil testing?

You request a site inspection from the Building Official. Depending on soil and location, the county may require a system designed by a Colorado certified engineer. A percolation test may be used to verify the soil analysis.

What are the inspection rules?

Request an inspection once all components are in place, connected and ready to cover. The guidelines say not to cover any part of the system before inspection. Engineered systems must be inspected by the designing engineer, who provides a certification letter. Final approval requires proper backfill and an "as built" plan.

How does it fit with the building permit?

No building permit is issued until the OWTS design is approved. The OWTS must be installed, inspected and approved before construction is complete and a Certificate of Occupancy is issued. See my post on building permits.

What is the bottom line?

If you are buying land to build on, ask what septic design the site will need before you commit. Call the Building Department early.
