For several years now, the U.S. concrete pipe industry has witnessed a relentless attack on both professional engineers and the authority of local governments to set technical specifications for culvert, water, and wastewater pipes used in taxpayer-funded infrastructure projects.

Our goal is to protect and preserve the engineer’s authority to use his/her professional judgement in determining which piping materials are suitable for a particular project in a particular region of the country.
