The water information system : users of water information

The WIS-F / Aims / Data availability / Users

Public institutions and organisations The State, water managers, water users, experts and citizens all require water information. They need to know the aquatic environment characteristics on which their activity can impact.

A few examples.

• Decision-makers who need information on the impact of a dam on environmental quality in order to determine how to limit that impact (fish-passage systems or even the removal of the dam).   • An agri-food company looking to set up a new factory needs information on the available quantities, quality and cost of the water required to produce and to determine the sale price of its products.
• The water police, who must decide whether to grant authorisations for new work affecting rivers, e.g. a new water-treatment plant or a unit to produce drinking water, require reliable data on the chemical and biological quality of the aquatic environment and on flow rates. • A farmer who wants to buy a farm needs to know if the available water resources are sufficient for the proposed activity. He also needs information on the quality of the water used to irrigate crops as well as solid meteorological data.
• The Water agencies need information on the quality of water resources and aquatic environments to set up, for their river basin, coherent tariff zones and fees on the water consumed and pollution of aquatic environments. • Companies and farmers must receive information on the effects of their water use, on any measures set up to deal with the situation and on the cost and effectiveness of the measures.
• A local government wanting to build a water-treatment plant must first learn about the environment to limit the impact of effluents and ensure that the capacity of the environment to cleanse itself is sufficient. • Citizens may need information on the quantity and quality of drinking water or of bathing water in areas where they intend to move or to spend their vacation.
• Companies producing drinking water need data on the available resource before setting up production units and starting to draw from aquifers.

• Public research institutes (BRGM, CEMAGREF, INERIS…) need data of water to carry out research programs and studies required to implement water policy
