“In 2009, DPOR adopted licensure requirements for onsite sewage systems professionals, including installers. Part of the reason for licensure was to recognize that onsite systems are becoming increasingly complex and require specialized training of individuals involved in designing, installing, and operating them. VDH does not require that an installer provide their onsite installer license number on construction completion statements. As a result, installations are being done by unlicensed individuals. There is no incentive for unlicensed installers to obtain their license. VDH should amend the regulations to require an installer to provide their onsite installer license number on construction completion statements. This will ensure that only properly trained and licensed persons install onsite systems in Virginia.”
