Anglian Water invest £1.7m into Norwich’s sewer network

08 April 2024


Anglian Water’s @one Alliance is planning to work to reline more than 530m of a sewer pipe in Norwich, improving the sewer network’s resilience and prevent flooding. This work to reline the sewer will ensure that customers in Norwich can continue to use their taps and flush their toilets for years to come.

The work is due to begin in April 2024 and is expected to be complete by the summer and it represents an investment of £1.7m into Norwich’s sewer network which will keep sewers flowing for the future.

Sewers need maintenance to keep them flowing and ensure pollution doesn’t find its way into the environment and to make sure people can keep flushing their toilets as normal.

Lee Forth Project Manager said: “Damaged pipes put the sewer network under a lot of pressure, which can result in burst sewer pipes. If repairs are not made in good time, this can cause a loss of drainage and toilet facilities for customers, as well as risking flooding and pollution in the natural environment.

“That’s why it’s important that we carry out this work to reline the sewer network in Norwich. This will prevent any disruption in sewerage services for local customers, as well as protecting local rivers and wildlife by minimising the risk of pollution.”

Anglian Water will be installing a new robust lining inside 530m of the existing pipe using innovative technology which will prolong the pipe’s lifespan and prevent groundwater infiltration which can cause flooding and pollution. By using this technique, it removes the need to dig up the road surface making it less disruptive and more efficient than replacing a pipe.

During the project, a temporary above-ground pipe will be installed to take away residents' wastewater. This also means there will be no disruption to customers’ facilities – so residents can continue to use their showers, toilets, dishwashers and washing machines as normal. This overground pipe will be removed once the relining work has been completed which expected to be in summer 2024.

As this work is a major construction project, there will be some traffic management in place to keep engineers and other road users safe. Road closures and updates on the works can be found here.
