Welcome to my blog.
North America's underground infrastructure is crumbling at an alarming rate, so smarter, more cost-effective and sustainable practices are needed.
Broader use of PVC pipe would solve this problem and enable municipalities to spend taxpayer dollars more wisely. To do this, local governments and utilities need to modernize outdated procurement practices that ignore corrosion-proof PVC pipe.
Explore our web site and visit my blog to learn about the exceptional performance and environmental attributes of PVC pipe, and why it should be included in every bid for water and wastewater infrastructure.

Industry expert and Uni-Bell PVC Pipe Association Executive Director Bruce Hollands shares the facts.
PVC sewer pipe is manufactured and tested per ASTM standard F679 and is now available in sizes up to 60 inches. Fiberglass sewer pipe is manufactured per ASTM standard D3262 and is available in diameters of 24 inches and larger.
The Truth About Pipe Stiffness and Pipe Deflection
Some fiberglass documents try to distinguish between PVC's pipe stiffness (PS) and FRP's nominal stiffness (SN), alleging that PVC needs to have higher pipe stiffness than fiberglass. However, science does not support fiberglass's contentions: the truth is that the same loadings applied to pipes with the same stiffness will result in the same deflections.
Science says that not only are fiberglass allegations unfounded, in reality the opposite is true: since PVC provides greater allowable pipe deflections, it is often the case that fiberglass is the material that requires higher pipe stiffness.
Comparison Shows PVC Advantage
For projects from 18- to 60-inch, PVC is the clear product of choice as shown by a direct comparison of the two materials. Click here for the PVC/Fiberglass Material Comparison Sheet.
Need Assistance with Your Large-Diameter Sewer Project?
If you are planning a large-diameter gravity sewer project, consider PVC instead of alternatives. PVC brings the same set of attributes to larger diameters that have made it the material of choice for smaller diameters for over 60 years.
