To respond to the needs of our many stakeholders we provide an overview of our performance and plans, along with additional information for specialist groups and to fulfil legal requirements.
Our Contribution to Yorkshire
Our Contribution to Yorkshire is the name for our work to enhance our understanding of the impacts we have on the environment, society, and the economy.
This approach looks beyond the financial balance sheet by applying a mix of accounting, economic valuation, and sustainability techniques to assess our impacts across the six capitals, and where appropriate, put a monetary value on those impacts.

Since privatisation in 1989, the water and sewerage sector has delivered substantial improvements in services to customers in England and Wales. These include significant improvements to the water environment and drinking-water quality, as well as improved focus on customer service.
Along with PriceWaterhouseCoopers PwC, we have developed this paper ‘The water and wastewater sectors: the long view’ which acknowledges the success of the industry to date and the challenges which the sector faces, now and in the future. A range of scenarios are presented which we hope will stimulate discussion on the long-term vision for the sector.
