Layer to Langford Pipeline

To ensure Essex & Suffolk Water (ESW) can continue to provide a reliable and resilient supply of water to its 1.5 million customers in Essex, it is looking to improve the raw water transfer capacity between its operating areas. To achieve this ESW are intending to construct a pipeline to transfer raw water from Layer-de-la-Haye Water Treatment Works to the existing storage reservoir at Langford Water Treatment Works.

Update by Daniel Wilson

Our Layer to Langford Pipeline Project team is using a non-intrusive method to cross two major Rivers in Essex, the River Blackwater and the Langford Cut.

The method, known as directional drilling, drills a tunnel beneath the rivers through which over 200m of pipeline will be pulled. The alternative to this would involve sheet piling the rivers to stop the flow, overpumping the water and then open cutting the rivers, potentially causing ecological and environmental disturbance.

Work started last week, beginning with the drilling of a pilot tunnel 6m beneath the river beds. This will be followed by work to widen the tunnel ready to accept the large diameter pipeline.

The drilling process itself is expected to take four weeks.
