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.

The Water and Wastewater Sectors: The Long View

Getting it right for our customers is at the heart of everything we do. That’s why we created our Blueprint for Yorkshire, planning our future with your priorities in mind. We’re pleased to say that last year, we met 24 out of 26 of the new commitments we agreed with our customers. That means we’re well on our way to delivering what’s important to you but know we have more to do. Read the full report for more information.
