On-site Wastewater Treatment Systems
San Juan Basin Public Health (SJBPH) is the regulatory authority for on-site wastewater treatment system (OWTS) permitting in La Plata, Archuleta, and San Juan Counties.
SJBPH has regulated OWTS, also known as septic systems, since 1967. Due to updated State of Colorado standards, SJBPH adopted new local Regulations that will go into effect on January 1, 2018.
- 2018 Regulations (as adopted)
- Colorado’s Regulation 43 (contains most of the design standards for OWTS)
SJBPH will offer classes and workshops for OWTS practitioners to become familiar with the requirements of the new Regulations. You can find more information and scheduling on the tabs below.

Anyone who wishes to install, construct, alter, or repair an on-site wastewater treatment system (OWTS) in Archuleta, La Plata, or San Juan Counties is required to first obtain a permit from San Juan Basin Public Health. Learn more about how to obtain an on-site wastewater system permit and prepare for site evaluation:
Please note: submitting an application for the installation of an OWTS does not guarantee a permit on marginal lots; marginal lots may be small in acreage, contain steep slopes, shallow bedrock, shallow groundwater or not meet setback requirements.
OWTS that will serve commercial properties or multifamily dwellings, and all OWTS located on unsuitable soil, high groundwater, high bedrock, or steep slopes must be designed by a professional engineer. On other sites, anyone may submit a design following a Site and Soil Evaluation, which determines if any of these conditions are present.
Regulations require that all OWTS be installed by a currently-licensed System Contractor and that the Contractor possess the authorization to construct the OWTS, signed by SJBPH, prior to breaking ground.

Construction inspections of new OWTS are scheduled through the permitting process.

For an inspection of an existing septic system that is more than four years old, two things are required:
First, the septic tank must be pumped by a licensed system cleaner. The cleaner will perform an inspection and report on the condition of the system. This report will detail activity(s) performed, septic tank volume, number of chambers in the septic tank, and any system deficiency(s), malfunction, or broken equipment observed, such as cracks, infiltration, overflows, or non-standard equipment. A copy of this receipt shall be provided to SJBPH, upon SJBPH’s request.
Second, using the form below, request that SJBPH perform an inspection of the surface features of the septic system. This inspection is accompanied by a search of SJBPH permitting records for the property in question.
Please note, a five day notice is required for inspections.
Inspections of existing systems can also be scheduled with an Inspector certified by the National Association of Wastewater Technicians (NAWT).
Anyone intending to install an OWTS in 2018 must complete a System Contractors Class and obtain a license from SJBPH. SJBPH offers the System Contractors Class several times throughout the year. Classes to obtain a 2018 license are as follows:
- Dec. 14, 2017, 1 p.m. (only for System Contractors holding a 2017 License)
- Jan. 24, 2018, 9 a.m. (only for System Contractors holding a 2017 License)
- Jan. 26, 2018, 9 a.m. (new and returning Contractors)
All classes will be held at the SJBPH Durango offices, 281 Sawyer Drive. Dates and times are subject to change. Advance registration is required! Call 970-335-2030 or email firstname.lastname@example.org to register. Licenses expire at the end of the calendar year.

Beginning January 1, 2019, most properties served by a septic system in Archuleta, La Plata and San Juan Counties will be required to undergo inspection prior to sale. This requirement helps identify failing and hazardous systems and protects property buyers from unforeseen repair obligations. In 2018, these inspections are optional.
Inspections for Transfer of Title purposes must be performed by an inspector certified by the National Association of Wastewater Technicians (NAWT).
Septic tanks must be pumped by a licensed System Cleaner as part of the required inspection. Inspection reports are valid for twelve months. Inspection reports for Transfer of Title purposes must be submitted to SJBPH to obtain an Acceptance Document prior to closing. Acceptance Documents expire at the closing of the property sale, or after twelve months, whichever comes first. All Acceptance Documents are contingent on proper permits existing for the septic system.
The following situations will be exempt from mandatory Transfer of Title Inspections:
- The OWTS received a final permit from SJBPH within the last four years.
- The transfer is not an arm’s length transaction (for example, inheritance, including a spouse)
- The transfer is creating or ending joint ownership, with one original owner remaining on the title
- Creating trusts and LLCs in the same name as the original owner
- Foreclosure (note: sales of bank-owned properties will NOT be exempt)
- Repair or alteration permits are active for the OWTS in question
The Transfer of Title Inspections requirement is delayed until 2019 to allow for more time for homeowners, real estate professionals, and the wastewater industry to prepare for the new requirements.
