This two-fold publication has been in circulation since 1989. Apart from several reprints and minor amendments to text, major revision has not been necessary until this year.

During the spring the Technical Committee of the Water Management Society undertook to revise the publication in line with current thinking and to reflect the increased emphasis on Health and Safety Responsibilities of Owners.
