Dual contained pipework installed at water treatment works

Paul Boughton

Durapipe’s specialist dual contained pipework system, Durapipe Guardian, has been installed as part of a refurbishment project at Rivington Water Treatment Works in Lancashire, England.

A United Utilities facility, Rivington Water Treatment Works was undergoing an upgrade to its plant, which included replacing the existing pumps and tasked contractors Byzak with installing a pipework solution to feed the new pumps.

The pumps are utilised in the water chlorinating process and so the pipework was needed to transport sodium hypochloride from the bulk storage tanks to each of the seven new pumps. Needing a pipework system that could safely transport the specified chemical substance, Durapipe Guardian was selected as the most effective solution.

The pipework was being installed in the ceiling voids of the plant so, due to the nature of the chemicals being carried, it was vital that the system was dual contained to prevent any potential leakages spilling out into the plant and endangering unprotected workers.

After investigating a variety of different options for dual contained pipework systems, Byzak opted for the Durapipe Guardian system due to its chemical resistance properties and ease of installation. Its corrosion resistant properties also ensure that the pipework system operates effectively over the lifetime of the system, reducing maintenance and replacement costs.

Commenting on the project, David Fielding from Byzak, said: “Sourcing a reliable secondary containment system was imperative for this project to ensure the health and safety of those working at the plant.
“When we began searching for dual contained pipework systems, we looked at a number of options on the market. Durapipe Guardian was the leading product in terms of performance capabilities and installation properties.”

Incorporating Centralok system, Durapipe Guardian is the only dual containment system which provides a solid inner pipe fitting, making it easier to install as the inner pipe is in a fixed position and can be easily jointed, compared with alternative dual containment products where the inner section moves freely.

Manufactured in PVC-U material, Durapipe Guardian allows the safe transportation of different fluids and some chemical concentrates without fear of corrosion and environmental pollution. Durapipe Guardian is available in sizes from ½”#2” up to 8”#12”.
