Water Supply (Water Quality) Regulations 1989
The Water Supply Water Quality Regulations 1989 (SI No. 1147) are regulations imposed on the England and Wales Water industry by statutory instrument. The regulations were signed jointly by Peter Walker, Secretary of State for Wales and Michael Howard who, as Minister for Water and Planning, was responsible for implementing water privatization in England and Wales during 1988/89. Most of the measures came into force on 1 September 1989, and the rest on 1 January 1990. The regulations have been superseded by several later instruments. Revocation 
The 1989 regulations were revoked in England by the Water Supply (Water Quality) Regulations (SI 2000/3184) and in Wales by the Water Supply (Water Quality) Regulations (SI 2001/3911). Further changes were made by the Water Industry Act 1991. Wholesomeness
