Water safety planOperational decisions :
Raise people’s awareness of water scarcity The fight against water waste program
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

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. »

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.

Groundwater research campaign
A few structuring scenarios to study :Building of an impounding reservoir (reservoir on the
Auzance river)Desalination of seawaterWater transfer from the South of the Vendée
(Mervent) to coastal areas (Apremont)Transfer of treated water from Nantes (water plant
in La Roche) to the North West of VendéeRe-use of water from wastewater treatment plants
Strategic direction of Water safety plan
Water framework directive of October 22, 2000Ensure the ecological stability of waterways1964 and 1992 laws on water / 2006 laws on water and
on aquatic environments SDAGE Loire-Bretagne
Water orientation and planification documents for the Loire-Brittany area SAGE (Auzance Vertonne / Vie et Jaunay, Lay, the Vendée …)
Orientation documents for the catchment area

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
Operational DecisionsFight water waste
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
Operational DecisionsFight water waste
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)
Operational DecisionsFight water waste
