| | Sustainable Development Home | Indicators Home | Introduction | |
There have been significant improvements in both chemical and biological river quality in English rivers since 1990, bringing more of them up to the standard found in the rest of the UK.
In 2001, abstractions for public water supply were 8 per cent lower than in 1991.
In 2002-3, 30 per cent less of the water put into the supply by water companies in England and Wales was lost through leakage than in 1994-5.
