Precast concrete wastewater treatment tanks have exceptional watertightness. Many jurisdictions require watertightness testing at the manufacturer location or on the job site. It’s important to know how to properly execute these tests for reasons of safety and reliability. During this presentation, part of NPCA’s Specifier series, presenter Claude Goguen, P.E., will first discuss existing standards of hydrostatic and vacuum testing for septic and gravity grease interceptor tanks. The webinar will focus on the procedure for both types of testing while sharing tips and tricks for success, and the equipment needed, especially for vacuum testing. Learn valuable information for manufacturers, installers, inspectors and regulators in the wastewater treatment industry.
Date: July 25, noon-1:30 p.m. ET
