This Act makes provision about the water industry and amends the Water Industry Act 1991 as well as makes changes to other legislation. The purpose of the Act is to reform the UK water industry by making it more innovative and responsive to customers and to increase its resilience to natural hazards such as drought and floods, and gives the Water Services Regulation Authority (Ofwat) new powers to make rules about charges and charges schemes, as well as making provisions for flood insurance and drainage boards.
