§ Mr. Gordon Wilsonasked the Secretary of State for Scotland how much of the sewerage system in Scotland is over 100 years old; what proportion is in need of serious repairs and renovation; and what proportion of repair or renovation can be carried out over the next five years on estimated capital expenditure authorised.
§ Mr. RifkindFull information about the age and condition of the sewerage system in Scotland is not at present available, but a national sewer survey co-ordinated by the water research centre will be completed next year. It is for regional and islands councils to decide, within the capital allocations made to them, how much should be invested in repair and renovation.
