The Thames Water Authority (Amendment of Local Enactments) Order 1987
The River Wandle Protection Act 1908 permitted the abstraction of water from boreholes known as Waddon Wells subject to a prohibition on abstracting more than 50 million gallons in any 30 days. Abstraction, which was then carried out by the Croydon Corporation, is now carried out by the Thames Water Authority under the terms of an abstraction licence granted under the Water Resources Act 1963. That licence, has been varied on a number of occasions with the result that it now permits the abstraction of up to 80 million gallons in any 30 day period until 1992.
