Onsite Wastewater Regulations

The La Plata County Board of Health is required by state law to adopt regulations governing onsite wastewater (septic) systems to take effect January 1, 2024. The Board of Health adopted onsite wastewater regulations in September, which it will ratify in January.

La Plata County recognizes the need to minimize disruptions to the professional onsite wastewater treatment community during the transition period from San Juan Basin Public Health to La Plata County Public Health. To this end, the county adopted regulations that are closely aligned with those in place at San Juan Basin Public Health, and adhere to the requirements set out by the state of Colorado.
