Our Services



About us



In providing essential services to customers, Scottish Water is a large user of electricity, requiring around 445 Gigawatt hours (GWh) per year. Our efforts to reduce our energy bill and increase renewable generation saw us win the Renewing Scotland award at the annual Scottish Green Energy Awards in December 2015.

We have a three-pronged approach to energy management and development:

Energy efficiency
Increasing self-generation
Hosting private renewable investment

Energy efficiency

We have installed over 4,000 smart meters to measure consumption and help target opportunities. We have made changes to operational practices and our asset base to reduce consumption or move demand to cheaper tariff periods. We are also exploring and piloting other demand-side-response initiatives and long-term low energy, low carbon treatment solutions. We aim to reduce base consumption by 11GWh by 2021.

Increasing self-generation

Since 2013 we have doubled our installed renewable capacity to over 53 GWh and diversified our portfolio to include hydro, wind, photovoltaic solar and combined heat and power (CHP). We currently have 29 hydro turbines, 18 small scale wind turbines, 24 solar schemes, 2 biomass boilers and 2 CHP plants, helping to offset the amount of electricity we need from the grid, with several treatment works now self-sufficient.

We are also exploring private wire contracts which will connect our assets to adjacent third party renewable assets – for example local community owned.

Hosting private renewable investment

We host private investment in renewables on our estate where it provides a good return for customers and is compatible with providing high quality services.

Through a combination of our own investment in renewable energy, and hosting private investment on our estate, we expect to facilitate the generation of renewable energy amounting to more than twice the level of energy we consume annually by 2018.

In addition, we have seen our operational carbon footprint fall by over 15% since we began reporting it in 2006/07. SW now have the lowest combined operational carbon usage per ML treated in the UK water Industry. 

Scottish Water Horizons, one of our subsidiaries, also supports renewable energy projects. For example, in 2015/16, it invested £2.9 million in renewable energy schemes, and enabled the first UK heat from waste water scheme to be commissioned in Galashiels. Horizons’ food waste Anaerobic Digestion plant - the first large scale plant built in Scotland (6 GWh pa), helping to prevent the release of greenhouse gases from landfill – continues to operate successfully.

Our strategy is aligned with the Government’s Hydro Nation ambitions, supports a greener and stronger economy, and is a key part of our desire to reduce the cost of delivering water and waste water services for customers.

Investment Programme

Scottish Water Annual Report 2014/15

The fifth and final year of Scottish Water’s 2010-15 investment programme saw £470 million of investment in regulatory improvements to Scotland’s essential water and waste water infrastructure.

Across the 5 years, around £2.4 billion has been invested in the upgrading of treatment works, water mains, sewers and networks. This has seen the successful delivery of more than 3,300 capital projects ranging in size from the modernisation of pumping stations in the Scottish Borders and Highlands, to a major new water treatment works that serves Edinburgh and extensive upgrades to water mains.

The involvement of supply chain partners, contractors and construction companies in many of these projects has helped sustain employment opportunities and support  local economies.

We have continued to invest in research and innovation across core aspects of our water and waste water services, which will increase in the next regulatory period. We have, for example, developed a range of standardised equipment to achieve benefits such as reduced design and site commissioning time, less disruption to customers, higher build quality, reduced health and safety risk and lower costs.

We are now looking forward to delivering our £3.5 billion 2015-21 investment programme. We have developed a new delivery model which involves working in partnership with 3 new alliances to deliver both maintenance and improvements to our existing assets.

We are also developing rural frameworks which will allow us to work with smaller contractors to ensure efficient delivery of improvements to our assets at a local level.

Keeping You Informed

Scottish Water provides you with clear, fresh drinking water and also removes waste water from your property. We are committed to keeping you and your community fully informed and involved when our work and future plans may affect you. This work is varied and could include water mains replacement, waste water improvements or building new treatment works.
