On-Site Wastewater Treatment Systems

NOTICE: Effective June 13, 2022, we will no longer be conducting field work or final inspections on Wednesdays until further notice.
NOTICE: As of January 1, 2022, EPCPH will require profile pits for any site along the HWY 24 W corridor to remain open for site inspection, prior to issuance of an OWTS permit.

El Paso County Public Health inspects and regulates on-site wastewater treatment systems (OWTS). We protect public health and the environment by preventing human exposure to sewage and the contamination of our groundwater by ensuring the proper placement, design, installation, and maintenance of OWTS. We focus on regulation of wastewater treatment systems associated with both commercial and residential facilities that are not serviced by a municipal wastewater system. There are an estimated 30,000 operating OWTS in El Paso County.

Property Sale and Maintenance

Property Sale

El Paso County Public Health requires a property owner of a residence or other building/facility served by an OWTS to have an inspection of that system to demonstrate that the system is functioning according to design prior to the sale of the property. Each individual OWTS on a single property is required to have its own inspection and Property Sale Acceptance Document Application.  

Please complete the  application via PDF below and email to [email protected]. Once received you will receive further instruction for payment. The fee for submitting a Property Sale Acceptance Document Application is $55.

Operation and Maintenance (O&M)

Required to permit the reduction of soil treatment areas, vertical separation distances to limiting layers or reductions in horizontal separation distances by using higher level treatment systems are based on the criteria that these systems are functioning as designed. If these criteria are not met, failure or malfunction is likely, which could result in damage to public health and water quality.

EPCPH has developed a program of inspections, maintenance, recordkeeping and enforcement to ensure and document that higher level treatment systems are meeting the designed standards. Systems utilizing pressure distribution or an in tank treatment unit are required to provide a maintenance contract with a listed O & M Certified Inspector.  Additionally, all newly installed systems require the submission of a maintenance inspection every 6 months for the first year followed by annual inspection thereafter.
