Our work in Kilmun to upgrade the sewer network and help enhance the water quality in the Firth of Clyde started late September 2017 and is progressing well. Scottish Water’s delivery partner Amey Black and Veitch has completed the excavation and installation of the first septic tank in Kilmun at Hillrig/Duncan’s Cottage. Work is now ongoing to construct the associated pipework.

Unfortunately, concrete works associated with the new septic tank at Hillrig/Duncan’s Cottage were delayed due to inclement weather. As such, this section of work is now anticipated to be completed by mid-March 2018.

In total, there are three upgrade locations in Kilmun and one in Strone. After we have completed work at Hillrig/Duncan’s Cottage, which is now anticipated to be completed by mid-March 2018, work will move onto Strone in April 2018. This phase of work is expected to last around 16 weeks.                                                              

Once work is completed in Strone, we will return to Kilmun to upgrade the final two locations; at Lagganbhuie for around 10 weeks, followed by the final phase of work at Alderburn for around 10 weeks.

We have been working in collaboration with Argyll and Bute Highways to help reduce the impact of the works on the community. 

Work has been phased to reduce the impact on journeys along the A880. We have designed the new infrastructure to ensure that all work can be done under single lane closures meaning all routes will remain open and no full road closures are required.            

Scottish Water thanks local residents and commuters for their understanding and cooperation whilst these essential works are carried out.
