Pipe cleaning is being carried out in Cuckfield next week to ensure residents have fresh drinking water.
The deep clean forms part of the company’s ongoing programme to keep tap water flowing crystal clear.
Mark Rice, distribution manager for South East Water, said: “The fresh drinking water entering our mains after treatment is extremely high quality, however, over time deposits can build up in the pipes, particularly if the water is slow moving.
“Our team of scientists and engineers use information gathered from our customers, from water samples and historical data to develop a programme to ensure we flush the areas that need it most.
“We appreciate customers may have concerns about the water used during the process appearing to run to waste, but we only draw through our pipes as much as we need, and once the water reaches its journey’s end, it is directed into the drains to be recycled.
“To help minimise the risk of any disruption, we usually avoid flushing between 6am and 8am, and 5pm and 10pm, when demand is highest.
“Customers will receive advance notice if we are going to be working in their area, and we do encourage anyone with a medical condition which could be impacted by an interruption to their water supply to sign up to our Priority Services Register at southeastwater.co.uk/help.”
