Scottish Water announces £30M investment in Borders

A £30 million upgrade of the water services in the Borders has been unveiled by Scottish Water.

The project will deliver improved treatment processes and a more resilient supply to over 20,000 households and businesses across several towns and villages including Selkirk, Galashiels, Melrose, Lauder, Fountainhall and Newton St Boswells. The project will also deliver environmental benefits.

It will involve constructing a 7-mile pipeline between Selkirk and Galashiels, building a new water storage tank to the south of Selkirk, installing new treatment processes at the Howden Water Treatment Works near Selkirk and turning off the Manse Street Water Treatment Works in Galashiels, which is coming to the end of its serviceable life and converting it into a service reservoir.

The works will take place in phases over the next two years, with the vast majority on private land away from local roads. 

Mark Dickson, Scottish Water’s director of capital investment, said: “This work to improve the water supply for the Selkirk and Galalshiels area of the Scottish Borders will ensure we can continue to supply high quality water in the area long into the future. This project will enable us to provide a better, more resilient service than ever before.”

The project is broken down into three core elements – treatment, distribution and storage – and will be delivered by Scottish Water’s alliance partners, ESD and CWA.

By upgrading the treatment process at Howden Water Treatment Works, the company will be able to provide clearer, fresher water than ever before. Part of these works will include the installation of new filters at the site, which will force up to 14 million litres a day through 0.4 micrometre wide straws – 25 times narrower than the thickness of cling film.

A new water storage tank capable of holding nearly five Olympic sized swimming pools worth of water will be sympathetically landscaped in to the hillside next to the A7.

The 7-mile pipeline will connect the Manse Street Water Treatment Works to the new water storage tank in Selkirk. It will carry up to 5 million litres of treated water every day. 

The pipeline will also need to cross burns and rivers. Scottish Water said those crossings will be carefully managed to reduce any possible environmental impacts.

Manse Street Water Treatment Works, to the west of Galashiels, will be switched off in 2020 and converted into service reservoir. This will help to improve flows in the Caddon Water during dry summer periods.
