The National Association of Wastewater Transporters, Inc. (NAWT) provides an effective voice at the national level for the industry to provide a diverse set of services  and to be an education conduit for the industry. NAWT developed and launched a successful national certification program for individual sewage treatment system inspection. The inspection education program incorporated the USEPA proposed five management levels to provide the rationale and basis for inspecting onsite wastewater treatment systems. Over the past four years this has resulted in the training and examination of over 2,000 inspectors. Currently there are over 1,100 inspectors registered on the NAWT website which is hosted by Cole Publishing.  The NAWT level of inspection is at the operation level. It requires the inspector to locate and identify all parts of the onsite treatment system. Then the inspector needs to assess the condition of each part and determine whether it is operating properly or if there are system deficiencies to be corrected. To do this requires that all parts of the system be accessible and opened for inspection. This includes septic tanks, pump chambers, pretreatment media filters, aerobic treatment units and soil treatment units.

 

The NAWT program requires inspectors to complete 8 hours of continuing education every 2 years to maintain their certification.
