The Uni-Bell PVC Pipe Association (PVCPA) was founded in 1971 as a non-profit organization and is the authoritative source of information on PVC water, sewer, and reclaimed water pipe and serves the engineering, regulatory, public health and standardization communities. Our mission is to promote use of longer-life, lower-maintenance, corrosion-proof PVC pipe in water and wastewater systems – for real sustainability, strength and long-term asset management.
