Founded in 1949, the American Concrete Pressure Pipe Association (ACPPA) is a nonprofit trade association representing manufacturers of concrete pressure pipe on the North American Continent. ACPPA sponsors research projects and conducts educational programs to promote and advance the use of concrete pressure pipe in water and wastewater applications. The association also manages a compliance audit and certification program through Lloyd’s Register Quality Assurance (LRQA), a leading global business assurance company. Each year, LRQA independently audits every ACPPA member plant to certify compliance with all applicable AWWA standards for the manufacture of concrete pressure pipe.
