A few key figuresDid you know that ?

The average daily water comsumption per person :In France : 151 litres on average

In the Pays de la Loire region : around 138 litres

In Cyprus : around 85 litres (figures for 2005 to 2007)

The water footprint concept or « virtual water »Litres of water required to produce : 1 kg of lettuce → 25 litres 1 kg of wheat → 1 500 litres 1 hamburger → 2 400 litres 1 glass of orange juice → 170 litres 1 ton of steel → 20,000 litres 1 ton of plastic → 2 million litres A car → 35,000 litres 1 ton of medecine → 5 billion litres A pair of shoes → 8 000 litres

How is water consumptiondistributed (in France)

2007 : 3,906 m3

2008 : 4,186 m3

2009 : 4,507 m3

2010 : 4,479 m3

NB : A large swimming-pool holds about 500 m3 of water. A year’s water consumption in Savary de Mauléon would fill about 9 swimming-pools.


General code for territorial groupingsArt.L2224-7-1« The communes have jurisdiction over the matter of

drinking water distribution. Within this framework, they settle upon a drinking water distribution scheme defining the areas served by the water distribution network. They can also provide drinking water production as well as its transportation and storage. »

1936 – 1955 :

Jurisdiction : Drinking water distribution to 276 communes in Vendée

Jurisdiction : Drinking water production

20 inter-communal syndicates and 2 communes

Amalgamation into inter-communal syndicates

276 communes in Vendée out of 282

Amalgamation into a single departmental service

The missions of Vendée Eau Operate and maintain the public service of water

distribution on behalf of communes, that is to say supply drinking water in sufficient quantity.

Satisfy people’s needs and activities while respecting present quality standards.

Origin of the water supply45 200 000 m3 of water produced in 2009 90 % surface water

12 water dams and 10 water production plants5 % groundwater 12 groundwater abstractions and drillings5 % water imports, mainly from Loire Atlantique

Strategic direction of water safety plan

Increased needs in summertime

→33 % of the water is consumed during summer months (June, July, August), half of which in the coastal areas

Growing needs in the coastal areas and in the North East of the Vendée departement.

Operational Decisions Fight water waste

Programme (2008-2012) : Targeting communitiesGoals Carry on the programme initiated with specific diagnoses Encourage the use of hydro-saving devices Encourage people to watch their water consumptionActions Diagnosis survey results, thoughts on the continuation of the

survey, updating database records Advice and technical support from communities

Editing guides, providing IT tools, advice for installing hydro-saving devices, AEU/HQE project monitoring (HQE = High Environmental Quality)

Operational DecisionsFight water waste

Programme (2008-2012) : Targeting private individuals

Goals Carry on water information campaigns to promote water

conservation Incite people to install hydro-saving devices Start new and more concrete test actions


Programme (2008-2012) : Targeting private individualsActions Carry on parntnerships and find new ones Develop pilot actions Install water-saving devices in show houses Improve our knowledge on water

consumption ratios Promote water-saving appliances Carry on marketing communication Release new documents Partnership with media Gardening charter


Programme (2008-2012) : Targeting studentsGoals

Initiate a teaching programme for the fight against water waste

Meet schools’ requestsActions Setting-up an educational programme Intervention in schools Water consumption assessments in schools and installation support for water-saving appliances

(Eco-school)
