We’re always working to reduce the number of leaks and bursts we have across our network and ensure we continue to supply top quality drinking water.

With this in mind, we’re going to be making some improvements to the water network in the Staplecross, Northiam and Horns Cross areas of Sussex.

What’s going to happen and when?

We've made some changes to our planned work to replace around 6,000 metres of water pipes in different phases in the Staplecross, Northiam and Horns Cross areas of Sussex.

We were due to start work on the first phase of the project on Wednesday, 28 October, but due to unforeseen circumstances, that was not possible.

As a result, we’re now planning to start work on this phase on Monday, 16 November 2026.

We’re sorry that we were not able to provide advance notice of this, and we’re working with East Sussex County Council to agree dates for further phases of the planned programme.

What’s going to happen and when?


Work in this first phase will include laying around 2,375 metres of new mains in the Staplecross area, starting along Horseshoe Lane, with a road closure in place from Monday, 16 November from the junction of Main Street to Little Gate Bungalow on Horseshoe Lane.

Work will be paused over the Christmas period, before resuming in the new year, from Monday, 4 January.

Further work will follow in other roads, including Furnace Lane, King’s Bank Lane and the Northiam and Horns Cross areas.

Dates for these sections of work are still to be confirmed, and we will write to you again to inform you of these, once agreed.

In total, we expect the whole project to take around two years to complete in full, across the different phases. We’ll do our best to get the work done faster if we can.

Public events

We plan to hold drop-in sessions to discuss further phases of work in this project and we’ll provide the details for these on our website in due course.

Road closures and diversion route maps

Rolling road closures will be in place for the safety of motorists, pedestrians and our work force. The first of these will be on Horseshoe Lane, starting on Monday, 16 November, 2026.

Work follows on in further phases in Furnace Lane and King’s Bank Lane.

Diversion routes will also be in place during the road closures, with full details of these to be published on this page, once confirmed with East Sussex Highways.

The road closures are in red, with diversion routes in blue in the maps below, while we work in Horseshoe Lane, Furnace Lane and King’s Bank Lane.
