§ Mr. Andrew WelshTo ask the Secretary of State for Scotland if he will provide figures for the separate costs of liming and orthophosphate treatment in the water supply in Scotland in each year between 1979 and 1990, inclusive, and for the projected annual cost of these treatments from 1990 to 1998; and if he will make a statement.
§ Lord James Douglas-HamiltonThis is an operational matter for each regional and islands council and such costs, which will vary considerably between individual treatment works, may not be separately identified. Costs incurred by authoriies for particular treatments to meet individual water quality standards are not recorded on a national basis.
