We're constructing a new pipeline to take treated water from Fleetwood Wastewater Treatment Works to strengthen and improve resilience to the wastewater network in Rossall. The new pipeline will replace the existing treated water outfall, and our construction partner is working at all of the shaft locations.
 
We do understand this work may cause some disruption to local residents and road users. Our teams will do everything possible to minimise impacts and we thank you for your patience and understanding while we deliver this important upgrade.

Latest updates

Work is well underway, with the first of the two specialist tunnelling machines now operational. We're on track for the main construction activity to be completed at the end of October/early November 2026 and reinstatement activity will then follow, which will extend through to spring 2027.

We're using specialist tunnel boring machines (TBM's) to construct the new pipeline which are designed to operate continuously to prevent engineering challenges. We recognise that 24-hour working may cause some disruption and have been working with our construction partner to alter the sequencing of our programme with continuous monitoring and additional measures in place to reduce disturbance as much as possible.

Shaft 1 (Amounderness Way)

Work to construct the tunnel shaft is continuing and is expected to be complete by the end of September.

Shafts 5 and 7 (West Way)

The tunnelling machine has completed its drive from Shaft 7 to Shaft 5. The outfall pipe will now be installed and commissioned. Once these works are complete, reinstatement will begin across each area.

We're here to help and support the local community as we're carrying out the upgrade

The project is complex with an evolving programme and we're here to help if you are concerned about the impact of the work. Please don't hesitate to get in touch to discuss with our team, so we're aware of individual circumstances. Our team will be happy to answer your queries and provide updates at our project information cabin or community drop-in sessions.

Key milestones

Broadwater Wood before/after

January 2026

One of our tunnelling working areas to facilitate construction of the new pipeline is in Broadwater Wood. While some trees and shrubs were cleared to create a safe working area, every effort was made to minimise the impact. Reinstatement and landscaping are included in our plans and we are working closely with Wyre Borough Council.

United Utilities employees working on the project

March 2026

We were able to begin work on site in January 2026 with ground investigations and design activities, followed by the start of shaft installation works in March 2026.

Great British spring clean

April 2026

Members of our project team took part in a litter pick in the woods as part of the Great British Spring Clean, collecting and recycling glass, plastic and metal waste.

TMB launched

May 2026

In May 2026, the first TMB was launched.

Installing the pipe

August 2026

We installed the first and second sections of the pipe in August 2026.

September 2026

We are on track to complete the tunnel works by the end of September.

October 2026

Installation of the product pipe and final connections aim to be completed in October 2026.

November 2026

Final testing and commissioning is expected to begin this November.

Spring 2027

Once construction is complete, full reinstatement activities will take place through to spring 2027.


We really appreciate the continued patience and understanding from the local community.
