It’s no secret that certain pollutants can degrade standard MDPE (Medium Density Polyethylene) pipes and put your water supply at risk. Contaminated soils are often found at brownfield sites – areas which were previously used for industrial or commercial works but are no longer in use.
The government actively encourages regeneration and development projects at brownfield sites – either to build more houses, warehouses or factories – to not only make the most of disused land but to protect the greenbelt and minimise urban sprawl. But, depending on the level or type of soil contamination, the water company may specify that a barrier pipe system is used to protect drinking water from the permeation of soil contaminants through the wall of the pipe.
What is barrier pipe?
Barrier pipe is a reinforced pipe that is used to safely distribute drinking water through contaminated land.
Several types of barrier pipe exist today, including ductile iron, plastic-coated copper and multi-layer plastic pipes with a metal layer. The latter is the most common type used for water supply pipes – and the one we supply, here at Cotterill Civils.
Our barrier pipe systems have a polyethylene core, surrounded by a protective metal barrier and covered with another layer of polyethylene. These are easily distinguished by the black/brown stripes along the length of the outer plastic coating.
Why use our barrier pipe system?
Our cutting-edge barrier pipe system is designed to provide the level of protection required and approved to safeguard potable water against contaminants, typically found in brownfield sites.
As a multi-layer composite structure barrier pipe, it combines the benefits of polyethylene (PE) with the exceptional barrier properties of aluminium (Al) – making it the system of choice to safeguard potable water.
Both lightweight and flexible, our barrier pipe system is quick and easy to install – without the need for thrust blocks and to post-wrap the finished joints. The pipe can be connected using almost any installation technique with our comprehensive range of barrier pipe fittings, specifically developed to give you the assurance of a safe and durable solution that protects your drinking water supply.
Another reason why you should use our barrier pipe is that we offer competitive pricing across the board, and all our prices are inclusive of VAT. Plus, many of our products come with the UK’s longest guarantees so you can be confident that you’re receiving the best value for your money.
