Scottish Water nears completion of million pound upgrade to Dollar WwTW in Clackmannanshire

Scottish Water is close to completing a million pound project to upgrade a Clackmannanshire waste water treatment works.

The Devon Way site in Dollar plays a crucial role in treating waste water, handling up to 1500 cubic metres per day. However, after around 30 years, the equipment was nearing the end of its serviceable life and needed to be upgraded.

The first phase required a giant 300-tonne crane to be brought to the site to install temporary treatment machinery to used during the upgrade while the investment work was carried out.

Ten months on, the crane and other heavy machinery is now needed to demobilise the site and a special track will again be laid to protect the road surface along the single track road which provides access to the site. Devon Way will be closed between the A91 west of Dollar and Walton Crescent from Wednesday 13 August to Monday 18 August 2025.

Scottish Water says it is investing record amounts – more than £2 billion over the past 10 years - to address the challenges of ageing assets, increasing demand and climate change.

The Dollar Waste Water Treatment Works project is being delivered by WGM Engineering.
