On-Site Sewage Facility (OSSF)

On-Site Sewage Facility (OSSF) Installation & Modification

On-Site Sewage for new structures shall only be allowed on lots which are a minimum of one (1) acre.  All OSSFs shall be permitted and inspected regardless of lot size or acreage tract.  OSSFs may be utilized only for disposal of normal domestic wastewater.  No industrial waste may be discharged to any OSSF.  No person may cause or allow the installation of a new OSSF when part of the lot or tract on which the OSSF is proposed is to be within two hundred (200) feet in horizontal distance of an existing sanitary sewer system unless the person has received a written denial of service from the owner or governing body of the sanitary sewer system or the person has received a written determination from the Designated Representative that it is not feasible for the person to connect to the sanitary sewer system.

Be SepticSmart (OSSF Maintenance)

All new aerobic septic systems are required to have a maintenance contract with a licensed Maintenance Provider in the initial two (2) years of service. The City of Cedar Hill encourages all homeowners with aerobic septic systems to continue a maintenance contract with a licensed Maintenance Provider following the initial two years to ensure proper functionality. Failure to properly maintain a functioning septic system shall result in but not limited to violations, fines and additional enforcement actions.

If you are not properly maintaining your septic system, you are hurting the environment, putting your family's health at risk, and may be flushing thousands of dollars down the drain!  EPA's SepticSmart initiative is a nation-wide public education effort that aims to inform homeowners living on properties serviced by septic systems on the importance of properly maintaining their septic system. It also provides valuable resources to help homeowners make important decisions regarding their wastewater management needs.
