Economic Analysis Of Water Reuse In Spain
Author(s)
J. M. Moreno & L. D. Chabalina
Abstract
The remarkable development of reuse of water in Spain has taken place not only
because of the necessity to extend water supplies, but also due to the
requirements to improve the management in water treatment. Water supply
consumption has increased, along with the increase of population that has taken
place in numerous urban zones. As a result, traditional supplying sources are
insufficient to satisfy the demand, which is in permanent expansion. This paper
will analyze from an economical point of view, the effects of the Directive
91/271/EEC in Spain, as well as the new rule that appears in the Order in
Council of December 8, 2007 in which the legal regime of treated water reuse is
established. Furthermore, costs of reused and recycled water by means of
different treatment systems will be discussed, as well as the environmental costs
associated to them.
Keywords: treated water reuse, economic analysis, environmental and economic
costs, legal regime.
1 Introduction
The increase reached by water supplies, as well as the increase of population
which took place in numerous urban areas, have caused that the traditional
supplying sources are insufficient to satisfy the demand, which is in permanent
expansion. Environmental limitations and plurianual droughts have led numerous
towns to use treated water as an additional water source to take advantage of it,
in case drinkable water quality was not necessary. At the same time, sanitary and
environmental requirements of continental and marine water quality are rising, in
addition to the requirements of location and treatment levels which are more and
more strict. For that reason, recycled water has been turned into an alternative
