COMPARISON OF WATER PIPE FAILURE RATES IN USA AND CANADA

PVC has the lowest water main break rate of all pipe materials in North America.

EVALUATING LIFE CYCLE ASSESSMENTS FOR UNDERGROUND INFRASTRUCTURE

Sustainable Solutions Corporation (SSC) paper on the importance of using transparent and verifiable standards when determining the environmental impacts of a pipe product. No other pipe material has disclosed environmental impact to as transparent and regulated a degree as the PVC pipe industry.

HYDRAULIC ANALYSIS: PUMPING COSTS FOR PVC AND DUCTILE IRON PIPE

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

INDEPENDENT STUDY SINGS THE PRAISES OF PVC WATER PIPE

This article summarizes the findings of an AWWA Research Foundation survey of water utilities in the early 1990's of PVC pipe's performance.

PARALLEL INSTALLATION HIGHLIGHTS DIFFERENCES IN MATERIAL SELECTION

A PVC Pipe News article giving a contractor's perspective on installing different pipe materials.

PVC VS. DI PRESSURE PIPE: OCCASIONAL SURGE

Using constant flow volume to calculate occasional surge pressures, PVC outperforms DI pipe.

PVC VS. DUCTILE IRON (DI) PRESSURE PIPE FOR WATER MAINS

A comparison based on 60 years of waterworks experience... In reaction to their loss of market share, the DI industry has focused on raising concerns about PVC as the pipe of choice. We thought it was time to review this old list of competitive claims.

PVC VS. FIBERGLASS (FRP) GRAVITY SEWER

This comparison of PVC and fiberglass gravity sewer pipes is based on decades of flexible-pipe research and field experience. A review of the properties and capabilities of both materials shows PVC to be the better choice.

PVC VS. FIBERGLASS (FRP) MUNICIPAL PRESSURE PIPE

Comparison of PVC and fiberglass pipe for municipal pressure applications.

PVC VS. HDPE PRESSURE PIPE FOR WATER MAINS

This comparison of PVC and HDPE pressure pipes is based on: (1) For PVC pipe – decades of research and field experience; (2) For HDPE’s new PE4710 pipe – short usage history with yet-to-be-determined longevity. Even if the issue of PE4710’s longevity is ignored, a review of the properties and capabilities of both materials shows PVC to be better suited for water and sewer pressure applications.

PVC VS. HDPE PRESSURE PIPE: OCCASIONAL SURGE

Using constant flow volume to calculate occasional surge pressures, PVC outperforms HDPE pipe.

PVC VS. POLYPROPYLENE (PP) SANITARY SEWER PIPE - FOR CANADIAN MARKET

This Canada-specific comparison of PVC and polypropylene (PP) sewer pipes is based on: (1) For PVC sewer pipe – decades of research and field experience: (2) For PP’s new sanitary-sewer pipe – brief history of usage with unknown longevity

PVC VS. POLYPROPYLENE (PP) SEWER PIPE

PVC is the product of choice for sanitary sewer piping, used in more than 85% of new installations. The newest product in the industry is polypropylene (PP) profile-wall pipe, but “new” is not always better. In fact, the introduction of PP into the sanitary sewer market should be cause for concern for wastewater utilities.

TRENCHLESS TECHNOLOGY MAGAZINE SURVEY IN THE 2010 PIPE MATERIALS GUIDE

Shows that for trenchless applications PVC is by far the most widely used pipe, with the longest life cycle and is easiest to maintain or rehab (see pages 8-11).
