This document establishes the legal framework and administrative boundaries for the Wessex Regional Flood Defence Committee under the Water Act 1989. The order is issued by the Ministry of Agriculture, Fisheries and Food, acting under statutory authority to manage water resources and flood mitigation infrastructure within the designated Wessex region. It serves as a formal instrument of secondary legislation to define the committee's operational jurisdiction and membership structure.

Legal professionals and historians of UK water policy utilize this document as a primary source for understanding the administrative evolution of regional flood governance. It is a highly technical, narrow-focus legislative text intended for regulatory reference rather than general readership.
