This paper reviews the impact of increasing environmental concerns on the U
K water industry over the 30 years from early research in the 1970s to the
present. From being supply driven 30 years ago, with demand being regarded
as an exogenous variable, the focus is now very much on demand management.
The sustainability of the freshwater environment is now the central concern
. After laying down some basic principles, the impacts of this switch in fo
cus are identified in the context of the present situation. Some key areas
of environmental pressure are analysed together with current policy stances
in relation to both demand management and system expansion. The impact of
the introduction of domestic metering and related pricing strategies is a p
articular concern in relation to the former as is new water saving technolo
gy. The paper concludes with some thoughts for water resource planning in t
he 21st century, particularly in the context of new housing provision. Copy
