Pipe reliner saves major disruption Anglian Water, UK, was saved from causing major traffic disruption and expense when it was able to carry out emergency maintenance on a water pipe running underneath a busy road by using Scotchkote Pipe Renewal Liner 2400 by 3M.

When Anglian Water discovered a 400mm ductile iron main suffering from internal tuberculation that was causing issues in getting a clear water sample, it worked with main contractor Balfour Beatty to find its solution in the Scotchkote Pipe Renewal Liner 2400. Simply flushing the main would not have removed the material, and any aggressive cleaning would cause the tubercles to rupture and lead to high iron levels. The properties of Scotchkote 2400 allowed Anglian Water to scrape out the main and then apply a lining to prevent it from iron bleed.

“The team at 3M were extremely helpful and have provided great support in trialling this product, resulting in the subsequent successful emergency application. The data they provided allowed Anglian Water to assess the risks of trialling this new product (eg water quality). The speed at which it sets and the pipe is returned to supply meant we could control the impact to our customers.” Mick Renshaw, construction manager at Balfour Beatty, commented, “This successful trial identified the learning required to adapt procedures to allow the best productivity from this new technique. The next step will be to confirm its lining capability to withstand the forces from ground movement in high ‘shrink swell’ areas.”

technology company 3M and Anglian Water. A live trial of the solution in a mains renewal scheme in Boston, Lincolnshire, UK, enabled the water company to discover a new way to reline long lengths of pipe more efficiently and with little impact on customers. This particular pipe renewal liner was specifically developed for the rehabilitation of potable water pipe infrastructure to extend service life, reduce leaks and improve water quality. Paul Gamwell, client project manager at Anglian Water, said, “Providing a clean, safe and sustainable water supply falls within the responsibilities of Anglian Water Services and we are working proactively to ensure security of supply for current and future needs in areas where population increase is set to be a continuing trend.

The efficient repair was a result of a collaboration between diversified
