Scottish Water Offices – Dumfries

Scottish Water is a statutory corporation that provides water and sewerage services across Scotland. It is accountable to the public through the Scottish Government.

The organisation provides water to over 2.5 million houses and over 150,000 businesses in Scotland, supplying over 1.3 billion litres of drinking water every day. It also takes away 847 million litres of waste water from customers’ properties and treats it before returning it to the environment.

Its Milngavie water treatment works is one of the largest water purification plants in Europe, serving the city of Glasgow with over 1.5 million people.

Recently, in response to the Scottish Government declaring a climate emergency in 2019 and calling for the country to be carbon neutral by 2045, Scottish Water responded to this target by committing to net zero emissions by 2040, a full five years earlier. They recognise they will need to undergo a sweeping transformation during this time to achieve this.

It has worked with a panel of experts, and its stakeholders, to develop a trailblazing routemap, which sets out how they will lead their industry to net zero emissions by 2040 and beyond, and make a greater contribution to Scotland’s overall emissions ambition, including the need for the organisation to become more energy efficient and to embrace low-carbon constructions and use of low-carbon energy products.

With this in mind, lighting efficiency was very much on the agenda when Scottish Water required new offices to be built in Dumfries. Another important requirement was to ensure the lit environment reflected area occupants’ natural circadian rhythm, so products were supplied as tunable white versions.

On this project, Dextra worked with contractor WMQ Building Services and consultants RSP Consulting Engineers.


Dextra products used in the new-build offices included the Runway Continuous Surface/Suspended. This is a slim line aluminium luminaire available in three colour options suitable for surface mounting or suspended installation in continuous runs. The Runway Continuous Surface Suspended provides a seamless appearance that can be infinitely reconfigured to dramatic effect.
