Saltcoats Rising Sewer Main Upgrade
Project Overview
We are upgrading the rising sewer main between our pumping station in Saltcoats and treatment works in Stevenston.
The £5.5 million project will protect the local caravan park, golf course, bathing waters and wider environment.
It is the second phase of a multi-million-pound investment.
At A Glance
- To prevent future bursts and protect the environment
- £5.5million investment
- Delivered by Caledonia Water Alliance
- Work began in January 2026
Beauty Spot
The rising sewer main runs past a golf course and under a caravan park. The project will protect them and the local environment from future bursts
What We Are Doing
We are relining nearly 500 metres of rising sewer main.
A temporary overland pipeline will be constructed to carry flows while the underground pipe is relined through access pits at strategic locations.
Work on the temporary pipe began in January 2026 with flows being diverted by the start of the bathing season in June.
It is anticipated the relining work and reinstatement of the area will be completed by October 2026.

Why We Are Doing It
The Saltcoats rising main has burst on multiple occasions since 2022.
The first phase of a project to reline the pipe between Saltcoats and Stevenston was completed in October 2023, but there are known defects in the pipe downstream of the newly lined section.
The project will dramatically reduce the risk of a burst under the caravan park and protect the environment, bathing water, shellfish waters and customers.

The existing pipe was relined through access pits
Update May 2026
The scaffolding equipment required to carry out lining operations will be erected from Monday 18 May, with two phases of lining to begin on 28 May.
A temporary overland pipeline has been constructed to carry flows while this work is taking place. These overland pumps are now operational to allow flows to be diverted during the Bathing Season with SEPA being briefed accordingly.
We would like to thank everyone impacted for their patience and understanding while these essential works are taking place.
