Scottish Water has opened a new water treatment plant for customers in the remote, scenic coastal town of Stoer in north-west Scotland using state-of-the-art nano-filtration membrane technology.

The £4 million project was carried out by Scottish Water’s alliance partner ESD – a joint venture between Black & Veatch, Galliford Try and MWH – and contractor Ross-shire Engineering.

The plant was built and tested at Ross-shire Engineering’s facility in Muir of Ord before being split into large transportable sections. Reassembly and construction of the treatment plant then began on site in July 2017.

Joe Syed from ESD explained: “The new plant was pre-assembled using state-of-the-art technology in Muir of Ord before delivery to the site, minimising the length of construction work and the associated traffic. The result is a new treatment works, made in the Highlands, that will benefit Scottish Water’s customers in north west Sutherland for many years to come.”

David Kitching of Scottish Water added: “The way we have approached this project has allowed the plant to be constructed in a controlled environment, reducing risk to the workforce, improving quality control and significantly reducing the construction period.

“This membrane technology delivers enhanced filtration to deliver cleaner, fresher drinking water for our customers in the area for the foreseeable future.

“The new water treatment works also includes additional storage capacity on site and a standby power generator, meaning that it will be more resilient to any disruption caused by severe weather or other possible challenges.”
