Dalreoch, Dumbarton
Project Overview
We are upgrading the wastewater network at Dalreoch in Dumbarton to improve the environment on the River Leven by reducing spills and preventing sewer related debris from entering the environment.
The work is part of our £500m Improving Urban Waters programme.
At A Glance
- Preventing sewer debris entering the environment
- £4million investment
- Delivered by Caledonia Water Alliance
River Leven
The project will reduce spills and prevent sewer related debris from entering the environment during periods of heavy rain
What We Are Doing
We are installing new pipework to carry wastewater flows to a new storm overflow chamber. This will be fitted with a powered mesh screen preventing anything larger than 6mm from entering the water environment during periods of heavy rainfall.
The new storm overflow is being located under the overflow car park of Dalreoch railway station to allow the car park to remain partially open during construction to minimise impact on rail users.
The new chamber and outfall will replace the existing ones which are located under the Forge Metal Recycling scrapyard. These will be decommissioned.
The new overflow will be installed underneath the car park

The work is part of our Improving Urban Waters programme
Why We Are Doing It
The current storm overflow has been identified as a high priority for replacement by Scottish Water and the Scottish Environment Protection Agency (SEPA).
Under the banner ‘Draining the Rain, Enhancing the Environment’ the Improving Urban Waters investment will help reduce spills and prevent sewage related debris such as wet wipes from entering the environment during periods of rainfall.
Open As Usual
The main car park at Dalreoch railway station will remain open throughout the project
Latest Update - September 2026
We have now moved on to the third phase of our programme, which involves installing a new section of sewer pipeline beside Glasgow Road.
We have worked with West Dunbartonshire Council to develop a traffic management plan to ensure the safety of the public and our operatives while this work takes place.
A lane closure is in place on the eastbound carriageway of Glasgow Road until Monday 7 December, between Renton Road and the entrance to Dalreoch Railway Station car park. This closure is in place to allow for the safe installation of a new section of sewer pipe linked to the new storm overflow currently being constructed beneath the lower car park at the railway station.
Temporary five-way traffic lights are also in operation on Glasgow Road, West Bridgend, Renton Road and the access road to the railway station car park. These are expected to be in place until the early December. We appreciate that the deployment of these temporary lights initially caused significant local disruption.
On receiving feedback from the local community and road users, we have further reviewed our traffic management arrangements with West Dunbartonshire Council and our traffic management contractor, Sunbelt.
We would like to reassure you that we have traffic management operatives on site during the hours of 7am -7pm, Monday to Sunday, to manage the variations of peak traffic. Please note that this does not necessarily mean an operative will be visible standing directly next to the lights for 12 hours each day. However, we can assure you that they will be in attendance with a clear line of sight of the roadways. They will continue to monitor the situation going forward and intervene to make any changes as and when required to keep traffic moving.
***It is important that road users do not jump the lights as this action is dangerous, disrupts our automated traffic management process and will significantly prolong delays for everyone.***
We thank everyone impacted for their patience and understanding while we carry out these essential works.
