  3. ERHASYA Team Members • Team Leader: Anaïs Florquin • Master 2 Water - HYDRE (Hydrology, Risks and Environment) • Project Authority: Emile Rousseau • Master 2 Water - HYDRE (Hydrology, Risks and Environment) • Chief of staff: Serge Wardé • Master 2 Water - Water and Society • Communication Manager: Tiphaine Valois • Master 2 Water - H3E (Qualitative and Quantitative Hydrogeology, and Environment) • Assistant Communication Manager: Hélène Dentel • Master 2 Water - Contaminants, Water and Health • Assistant Communication Manager: Coralie Ranchoux • Master 2 Water - H3E (Qualitative and Quantitative Hydrogeology, and Environment) • Treasurer: Jérémy TormosEspinoza • Master 2 Water - Water and Society • Assistant Treasurer: MaélliaGaultier • Master 2 Water - Contaminants, Water and Health

  4. General Context Before • Water resources : Underground Water • DomesticWater (collective fountains) • IndustrialWater • Agricultural Water 1968 After

  5. Socioeconomiccontext • Communitybased city • Cosmopolitan (more than 50 nationalities) • Particulareconomic system • Donations • Local activities • No official water management structure

  6. Actualdrinkingwater system • Water treatmentcompany: AquaDyn - Auroville • Collective fountains • 3 filtration systems: • Activatedcarbon • Sediments • Reverse osmosis

  7. Geological and hydrogeologicalcontext • Aquifersoverexploitation • Drop in groundwaterlevel • Saltwater intrusion (proximity to BengalBay)

  8. Water supplypossibilities How to guarantee a sustainable water supply in Auroville ? Underground Water Wastewater Sea Water Rainwater - Significant volume available - Natural quality Overexploited Saltwaterintrusion Recycling and reuse, Difficultyto sustain a good qualitylevel Expensivetreatment
