The prescribed standards and values which drinking water must achieve
pose many general research themes and specific questions, some examples of
which are suggested here.

One of the key forecasts needed is the likely
demand for water. It is complicated by the
differing interpretations of demand made by
different sections of the water industry. Expressed
simply, perhaps crudely, the water industry has
only recently and incompletely started to
differentiate supply and demand. True water
demand, that is water use by people and industry
in a manner that is more or less responsive to price,
is the definition of demand that is used by those
sections of the industry that deal with pricing
structures, tariff policy and similar functions.
Resource engineers, on the other hand, refer to
'demand on sources' or 'demand on works', in
other words, supply. In addition to the price-
sensitive demands for individuals and companies
is a series of other water uses, some of which may
available to address environmental issues such as
the Shellfish Directive, the Bathing Water
Quality Directive, the Urban Wastewater
Treatment Directive and the Statutory Water
Quality Objectives.
