Modelling the effect of climate change induced soil settling on drinking water distribution pipes.

Polyvinyl chloride (PVC) has become one of the dominant construction materials for sewer systems over the past decades, as a result of its reputed merits. However, since PVC sewer pipes have operat...

A review on the durability of PVC sewer pipes: research vs. practice

The true value of a pipeline as an asset should be based on several factors that impact its service life. Those considerations include the consumption and production of raw materials, design, installation, operation and maintenance, and planning for the end of the pipeline’s service life; as well as, the corresponding environmental impacts at each of these life cycle phases. In this paper, a model is presented that allows utilities and engineers to evaluate the total life cycle cost associated with a water transmission pipeline. The model is designed to compare Ductile Iron (DI) versus PVC pipe, two of the most commonly used pipe materials. In addition to the tangible cost comparisons, the model also includes an evaluation of environmental impacts that need to be considered by utilities to build or replace a transmission pipeline. Results from scenario analysis for 8” and 24” pipes illustrate that although PVC pipes have initial economic benefits (due to lower material costs), DI tends to be more cost effective and also comparatively environmentally sustainable (less CO2 emissions) over its service life.

A Framework to Evaluate the Life Cycle Costs and Environmental Impacts of Water Pipelines

Pipeline networks for gas and water are the lifelines of our society. Most pipelines are buried, which obstructs direct monitoring of the pipes, and introduces the need for other techniques to prov...

Risk-based asset management: automated structural reliability assessment of geographically distributed pipeline networks for gas and water in the Netherlands

Polyvinyl chloride (PVC) sewer pipes have operated for decades in a hostile environment, raising concern among sewer managers over the longevity of their drainage systems. Inspection data (CCTV and...
