§ Mr. Clappison
My Department and Ofwat jointly commissioned a report, "The Social Impact of Water Metering" from W. S. Atkins Planning and Management Consultants, which was published in August 1992. In addition, the Office of Water Services commissioned a report from the Institute for Fiscal Studies, "The Distributional Effects of Different Methods of Charging Households for Water and Sewerage Services." That report was published in August 1993. Copies of both reports are in the Library.
