About Us
Established in 1976, NASSCO is the underground infrastructure industry source for education, technical resources, and advocacy. For the past 25 years NASSCO has trained more than 40,000 individuals in the proper inspection of sewer conditions.
Focusing primarily on larger main lines through its Pipeline Assessment Certification Program (PACP™), laterals (the pipe that conveys waste from the home or business into the main line) through its Lateral Assessment Certification Program (LACP™), and manholes via its Manhole Assessment Certification Program (MACP™), NASSCO now offers training on the proper inspection and cleaning of private property sewer and drains with the introduction of the Building Sewer and Drain Inspection Certification Program (BSDI™) and the Drain Cleaning Certification Program™.
