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, and the southwestern portion of Hinsdale County (by Williams Reservoir). SJBPH has regulated OWTS, also known as septic systems, since 1967.

Beginning January 1, 2019, most properties served by a septic system in Archuleta, La Plata and San Juan Counties are required to undergo inspection prior to sale. This requirement helps identify failing and hazardous systems and protects property buyers from unforeseen repair obligations.

Inspections for Transfer of Title purposes must be performed by an inspector certified by the National Association of Wastewater Technicians (NAWT). Inspectors can be found in two ways.

  • As a courtesy, SJBPH maintains an unofficial registry of local certified inspectors. This list is not official or comprehensive and you should verify that an inspector’s certificate is current before contracting with them to do an inspection. There may be other certified inspectors on the NAWT website that do not appear on SJBPH’s courtesy list.
  • Click here to search for an inspector on the NAWT website.

Inspection reports should be submitted on the following form: SJBPH Operating Inspection Form. SJBPH may accept reports on other NAWT-compliant inspection forms at its discretion.

SJBPH recommends having the septic tank pumped within 1-2 days of the certified inspection, and some inspectors may insist that it be pumped during inspection. Septic tank pumping may also be required depending on inspection results (if the inspection reveals that it has been too long since pumping). Confirm details with your chosen inspector, and click on the “Installers and Cleaners” tab above to find a licensed System Cleaner.

Inspection reports and reports from System Cleaners expire after 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. Click the green button above to search for existing permits by address.

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

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. Site and Soil Evaluations must be performed by Registered Soil Technicians. If you have the necessary qualifications to perform soil evaluations and wish to be added to the registry of Soil Technicians, contact SJBPH at 970-335-2030.

Regulations require that all OWTS be installed by a currently-licensed System Contractor and that the Contractor possess the permit to construct, alter or repair the OWTS, signed by SJBPH, prior to breaking ground. NOTE: Contractor licenses expire on December 31 and may not have been immediately renewed. Confirm with your contractor that their license is current for 2019.

Construction inspections of new OWTS are scheduled through the permitting process. Click the Permits tab above to learn more.

For mandatory inspections of existing systems for the purposes of transfer of title to the property, click the Transfer of Title tab above.

Information on this tab is for three situations:

  1. To request an inspection when required for a new building permit application or modular home permit application that proposes to reuse an existing OWTS.
  2. To request a voluntary inspection of an existing system for information purposes or to investigate a potential problem
  3. To request an inspection for purpose of finalizing an expired permit (check with SJBPH to confirm a new permit is not required before proceeding)

If one of these situations applies, follow the procedure below.

First, the septic tank must be pumped by a licensed system cleaner (if the tank was pumped within the last year, provide SJBPH that receipt and do not re-pump the tank). 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 voluntary inspections and inspections for building permit applications.

Inspections of existing systems can also be scheduled with an Inspector certified by the National Association of Wastewater Technicians (NAWT). A list of local certified inspectors can be found on the Transfer of Title tab above.

Anyone intending to install an OWTS in 2019 must obtain a license from SJBPH. Individuals without a 2018 license who wish to be licensed for 2019 must take the 2019 contractors class. SJBPH offers the System Contractors Class several times throughout the year.

Classes will be held:

  • January 25, 9 a.m.
  • April 26, 9 a.m.
  • July 26, 9 a.m.
  • October 25, 9 a.m.

All classes are held at the SJBPH Durango office at 281 Sawyer Drive. Dates and times are subject to change. Advance registration is required! Call 970-335-2060 or email eh@sjbpublichealth.org to register. Licenses expire at the end of the calendar year.

Those Contractors who were licensed in 2018 and wish to renew their license were sent an email or mailed letter with a renewal packet. Please return the packets to SJBPH by March 31, 2019 to keep your license current. Contractors who are renewing a 2018 license do not have to take a 2019 class.

SJBPH licensed cleaners:

  • Superior Septic Services (Durango, CO)
  • Ball Septic Tank Service (Durango, CO)
  • Alpine Septic Service (Pagosa Springs, CO)
  • Rocky Mountain Sanitation (Pagosa Springs, CO)

San Juan Basin Public Health makes On-site Wastewater Treatment System permit information (including the name of the original permittee and address) available on our website.

In order to comply with §18-9-313 C.R.S. regarding the online availability of a law enforcement official’s (and live-in immediate family’s) personal information, we will accept written requests by law enforcement officials to have their personal information withheld from our website.

Law enforcement officials (as defined in §18-9-313 C.R.S.) who live in a residence served by an on-site wastewater treatment system permitted by San Juan Basin Public Health, and who were the original permittee for construction, repair or alteration of the system, may request to have their information made unavailable to the public on our website. SJBPH will only remove permits from the public database if they are associated with the law enforcement official’s name or the name of their live-in immediate family.

To request removal of public information from our public database, complete the following form and submit it to our agency with a copy of your driver’s license and your law enforcement official ID.
