Lead water pipes which serve 3,500 homes in Kettering are to be removed at a cost of £1.5 million.
They are being replaced with plastic pipes ahead of new European standards on the amount of lead allowed in drinking water.
Work starts next month and will target 64 streets in and around Kingsley Avenue, St Peters Avenue, St Marys Road and London Road.
The entire project is expected to take until December 2014 to complete. The new European standards, which come into force later this year will see the limit on lead in drinking water more than halve, from 25 to 10 parts per billion.
Kettering is one of the first places to benefit from the replacement work because of the town’s high number of older properties, which are served by lead pipes.
Toni Holtby, Lead Strategy Manager for Anglian Water, said: “Awareness of levels of lead in the environment has increased during recent years with the move to lead free petrol and paints.
“Where lead is found in tap water, it usually comes from old lead pipe work connecting the property to the water main or in the internal plumbing. In Kettering we are now replacing large amounts of that old pipework as part of our continual programme of investment in improving water quality.”
She added: “With work on this scale there will inevitably be some disruption. We are working closely with Northamptonshire County Council to keep this to a minimum and there are currently no plans to close roads as part of this replacement work.
“We will keep people informed throughout the work and there will be public drops in sessions in the near future.”
The work only covers those pipes, known as communications pipes, which are owned by Anglian Water and which connect it’s water mains to people’s private service pipes.
The service pipes, which run from the building to its boundary with the street, are the responsibility of the property owner.
Toni Holtby said: “It is likely that if our communications pipe is lead then your service pipes will be too. “The surest way to prevent lead getting into your drinking water is to replace all lead pipework; however you can take steps to reduce the amount of lead levels at your tap.”
