Larger systems, or those with nondomestic flows, are permitted by Utah DEQ. Systems must be installed to the approved plans, changes need county approval, and the department must inspect a system before it is backfilled. Alternative systems, pressure distribution systems and holding tanks need operating permits renewed yearly. (source: Salt Lake County Health Department)
