As utilities tackle the challenges of rehabilitating and expanding aging water distribution, wastewater collection and electrical power networks, they are increasingly turning to trenchless installation methods to reduce cost and minimize disruption to the public. Horizontal directional drilling (HDD) continues to grow in acceptance as utilities gain experience with the installation method and the number of HDD contractors continues to expand. In many areas HDD installation has closed the cost gap versus direct bury, leading utilities and design engineers to increasingly incorporate HDD alternatives in the design phase of their projects. Prior to 2004, the primary pipe materials used in HDD applications were steel and HDPE.
PVC pipe, already installed in many infrastructure networks, now accounts for more than 70% of the new water pipelines installed in the U.S. The steady growth of PVC pipe in water and wastewater systems can be linked directly to its combination of high strength, light weight, corrosion resistance, and its proven performance record over the past half century. With its superior resistance to hydrocarbon permeation and oxidation by chlorine-based disinfectants, PVC pipe has proven to be an ideal choice to ensure safe, reliable drinking water while providing a long service life.
As HDD projects continue to increase in size, scope, complexity, and distance, owners, engineers, and drill contractors are turning to Fusible PVC® pipe to downsize boreholes, simplify reconnections, and reduce project risk with higher tensile strength. Since its introduction in 2004, Fusible PVC® pipe has gained rapid acceptance as a cost effective HDD solution through thousands of competitively bid municipal and industrial projects, and has established an outstanding operating record in thousands of in-service installations.
Neil Smith of Mears Group comments, "Fusible PVC® pipe is allowing us to establish new frontiers in HDD applications with plastic pipe. UGSI's project management, engineering, fusion services and construction support throughout each project are outstanding."
