In accordance with legislative rule 64 CSR 9, Sewer Systems, Sewage Treatment Systems and Sewage Tank Cleaners, all individual sewer system installers shall be certified. An individual sewer system installer is any person engaging in the construction, installation, modification, extension, alteration and location of an individual or an-on-site sewer system, sewage tank, or an excreta disposal system. Certification is not required of a driver delivering a part or parts of a system, a manufacturer who does not install a part or parts of a system, or an employee of a contractor holding a certificate, provided that the employee is under the direct onsite surveillance of a certified installer. Certificates are issued in two classifications: Class I certificate applies to the installation of standard soil absorption systems, soil absorption beds, holding tanks, effluent lift stations and grey water soil absorption systems. Class II certificate applies to those systems covered by the Class I certificate plus all alternative and other individual or on-site sewer systems as set forth in legislative rule 64 CSR 47, Sewage Treatment and Collection System Design Standards.
