Severn Trent water utility has awarded the £60M contract to replace Newark’s pipes to an alliance of Barhale and NMCNomenca.
The three-year contract will see the BNM Alliance replace more than 20km of pipes, including a 2.8m diameter tunnel from Crankley Point sewage treatment works to the southern end of Millgate and a 1.5m diameter tunnel under Queens Road and Sleaford Road.
The team aims to use tunnelling machines to replace some of the sewers, reducing the need to dig up large sections of road and therefore minimising impact.
“Newark is expanding rapidly and this is putting pressure on our ageing infrastructure. The existing water and sewer pipes in Newark have been serving the community for many years, but they are simply no longer able to cope with the extra demands being placed on them,” said Severn Trent programme manager Tim Sawyer.
“The result is an increased risk of interruptions to our customer’s water supply and, more worryingly, an unacceptable increase in the number of sewer flooding incidents. Sewer flooding is one of the worst things that can happen to our customers and we know that there are around 400 properties currently at risk of sewer flooding in the Newark area. This is not acceptable – and that’s why we have to do something about it.”
