Future of the water sector
Water companies are contributing expertise, perspectives and research to inform the debate on the future of water.
Thames Water has commissioned EY to explore the relationships between incentives, cost allowances and rates of return, given the importance of implementing a coherent, reasonable overall risk and reward package for PR19. (March 2017).
Portsmouth Water commissioned NERA to review Ofwat's recent consultation on setting the cost of debt allowance for the 2019 price review and in particular Ofwat's proposed approach to compensating for embedded debt costs. (January 2017).
The water sector has achieved much over the past 25 years as a result of sustained investment.
- Our beaches and rivers are cleaner.
- Our drinking water quality is amongst the best in the world.
- Leakage has been reduced by a third.
- Customer service has improved.
- Increased efficiency has kept average bills at little more than £1 per day.
Looking forward to the next 25 years and more, the water sector faces challenges from population growth, climate change, tightening environmental standards and changing customer expectations.
These challenges will require both significant further investment and continuing evolution of the sector's regulatory framework. This will ensure that the water sector can continue to deliver the outcomes customers and society want, efficiently and effectively.
Contributions to the debate on the future of the water sector from companies and water sector organisation are below. This page will update as further contributions are published.
