An ever-increasing demand • Water is a necessary condition for development. • Increase of population (3 BN more) increases water demand both directly and indirectly (i. e. demand for foodstuff) • Agriculture (2/3 or 3/4 of worldwide water consumption – 40 M new ha of irrigation=8000 m 3/s) • Resources ill-distributed • Strong need to increase water resource locally, particularly in coastal areas (2/3 population) at an affordable price ! (e. g. agriculture requires water at a cost smaller than 0. 5$/m 3) World Water Forum Presentation – Istanbul - March 2009 – © via-marina 2

Insufficient or costly solutions • Desalination: high cost ( 1$/m 3) and high energy consumption (>3 k. Wh/m 3) for relatively limited quantities (1 -2 m 3/s) • Inter-basin water transfers: limited applications difficult to implement • Transportation by tanker: high cost (>2$/m 3) and limited quantity (1 m 3/s ~ 1 tanker of 100, 000 t/day) World Water Forum Presentation – Istanbul - March 2009 – © via-marina 3

submariver®: A New Solution World Water Forum Presentation – Istanbul - March 2009 – © via-marina 4

Reuse • Transport farther away outfall of treatment plants • If no local demand for reuse • Caution: potential usage vs. quality of treated water • Turning the ecological constraint into a productive investment • Obtaining a social and economic return • Diminish water price for first users World Water Forum Presentation – Istanbul - March 2009 – © via-marina 5

Advantages of submariver® • Large quantities / long distances / long term • Fast implementation and construction • Low energy consumption hence more environmentally friendly and less sensitive • Transportation price (amortization included) allows agricultural uses beyond normal human consumption • Simple and sturdy, low maintenance • No waste, no chemicals, no technological dependance World Water Forum Presentation – Istanbul - March 2009 – © via-marina 6

Ready to Develop First Project • Proof of concept established: – >25 pre-feasibility studies under discussion – Preliminary studies under way • Technical studies achieved (past R&D>2 M€): – Suppliers and co-contractors identified – Prototype and laboratory tests soon under way • NGOs and Administrations have shown high interest and proven acceptance of our solution. • Award winner of Tremplin 2007 (co-organized by French Senate and Parisian business school ESSEC) World Water Forum Presentation – Istanbul - March 2009 – © via-marina 7
