On-site Sewage Treatment System Program

Rural Oklahoma homes rely on individual on-site wastewater systems as described in Chapter 252:641, Individual and Small Public On-Site Sewage Treatment System. Typically, individual on-site systems consist of a 1000-gallon septic tank and a dispersal field (network of trenches filled with pipe and gravel). Additional on-site systems available to homeowners include aerobic treatment units with spray irrigation, aerobic treatment units with drip irrigation, low-pressure dosing systems and lagoon systems.

The first step in designing or selecting an on-site system for your new home is to have a soil test performed on your property. The soil test identifies the characteristics of the soil on your property. Based on the results of the soil test, the size of your property and the number of bedrooms in your home an individual on-site sewage treatmentl system(s) is designed.

The second step is hiring a contractor to install the system that has been sized and designed for your property. All individual on-site sewage treatment systems are required to be inspected by a Certified Installer or the Department of Environmental Quality.

If you would like further information please contact your local DEQ representative or call 405/702-6100.
