§ Mr. Hardyasked the Secretary of State for the Environment what is the number of new sewage treatment schemes which still require to be constructed in England and Wales in order to achieve satisfactory effluent levels.
§ Mr. Eldon GriffithsI would ask the hon. Member to await the publication later this year of Volume 2 of the report on the River Pollution Survey. This will give information about the, number of existing sewage treatment works where the effluent is unsatisfactory and where schemes are required to make it satisfactory. These schemes may take the form of either an extension at the existing site,370W or construction of new works or diversion of the effluent to another works for treatment.
