A dwelling or non-dwelling that generates wastewater must have an onsite wastewater treatment (OWT) system that complies with Title 124 or be connected to a public sewer system or other wastewater works. In addition, only a properly certified professional may inspect, repair, pump or install an onsite septic system.
Any local requirements (city, county) are separate from and in addition to the requirements found in Title 124 that apply statewide. This information will help you to better understand the regulations and to make informed decisions about your onsite system and its proper operation.
