A deteriorating water main that has already burst once under a river in East Sussex is to be replaced.
South East Water said the work would be carried out under the River Ouse, next to the swing bridge at Newhaven, in order to prevent further bursts.
The firm said the mains pipe was originally installed under the river in the 1960s.
Engineers will drill a hole under the river and then pull the new water main through it.
Delivery manager Graham Webb said the pipe was in an extremely difficult location but the mains needed to be more reliable.
He said: "Clearly we need to act before any further bursts occur to ensure we can maintain water supplies for both existing and future customers."
Work is due to get under way later this month and be completed in May.
