Pipe Issues Blog

Welcome to the Pipe Issues Blog

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 To do this, local governments and utilities need to modernize outdated procurement practices that ignore corrosion-proof PVC pipe.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.

Comparing Pipe Hydraulics: The Importance of Equivalent Pressure Class and Declining "C" Factor for Ductile Iron (DI) Pipe

Jun 4, 2018  Bruce Hollands

This technical report examines head loss and pumping costs over 100-years for PVC and ductile iron pipe.

PVC Pressure Pipe Under Roads

Apr 18, 2018  Bruce Hollands

Some pressure pipe designers and owners are not comfortable with the use of PVC pressure pipes under roads. Their concern is that traffic loads will cause the pipe to over-deflect (ovalize).

Discussion of different joint types for storm-drainage pipe – soil-tight, silt-tight, and watertight.

PVC and HDPE Pressure Pipes: Material Comparison

Mar 2, 2016  Bruce Hollands

For municipal applications, PVC pressure pipe is manufactured and tested per the AWWA C900 and C905 standards and is now available in sizes up to 60 inches. HDPE pressure pipe is manufactured per the AWWA C906 standard in diameters up to 65 inches.

PVC and Fiberglass Gravity Sewer Pipes: Material Comparison

Oct 15, 2015  Bruce Hollands

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.

More than 40,000 North American water and sewer utilities use cost-effective, corrosion-proof PVC pipe today and it has been in service on the continent for more than 60 years.

Water Pipe Safety-Factor Reduction: A Risky Proposal from the HDPE Industry

Oct 9, 2013  Bruce Hollands

Conservative safety factors are key to the durability and cost-effectiveness of today’s infrastructure. Utility engineers have helped to ensure the longevity and high performance of North America’s piping networks by adhering to a minimum safety factor of 2.0 for their water system designs. Unfortunately, the polyethylene (HDPE) pipe industry is proposing a risky revision to the AWWA C906 standard that will reduce the safety factor on pressure class to 1.6. The change is based on material properties unrelated to pressure capacity and for which there is no precedence or valid scientific basis. Moreover, discussion of this issue has been muddled by the HDPE pipe industry’s inclusion of unrelated arguments about improvements in the “design factor.”

Pipe Material Selection Key to Cost-Control and Performance of Water Systems

Feb 28, 2013  Bruce Hollands

A 2010 U.S. Conference of Mayors report stated that spending requirements for the next 20 years (2009-2028) for both water and wastewater systems including capital, operations and maintenance and growth was $3.8 trillion. The underground pipes, as the EPA points out, are nearly 60 percent of the total costs and as a result are where municipalities can achieve significant savings. The cost of water pipes and their long-term performance are critical.

Sustainable PVC Pipe Helps Reduce Water Main Breaks in Indianapolis

Jul 10, 2012  Bruce Hollands

A recent article by Indianapolis Mayor Gregory A. Ballard, which appeared in the U.S. Conference of Mayors Water Council Newsletter, discusses how water main breaks declined in his city through the use of green, durable and cost-effective PVC pipe, realizing significant savings for rate payers
