- 3. Watersheds around the world are imbalanced The water footprint of humanity- Pollution and usage Hoekstra and Mekonnen, PNAS 2012;109:3232-3237 ? Red on the map indicates high pollution load (BOD) or high water usage ? For example, if polluted water is entering a river basin, clean environmental water is needed for dilution ? Alternatively the water resources are being usurped for agriculture, industry etc.
- 4. Ground and Surface water: Over utilized. Rainwater- underutilized. ? This figure indicates environmental footprints (red bars), compared to their maximal sustainable value (green circle) The three water footprints: ? Blue Water Footprint: Surface and groundwater usage – EXCEEDS SUSTAINABLE LEVELS ? Greenwater Footprint: Rainwater- underutilized ? Graywater Footprint: Amount of water needed to dilute polluted water to environmental standards- approaching the maximal sustainable limit ? How to reduce? Rainwater harvesting, Water treatment and reuse. This should not come at the expense of another footprint! Hoekstra and Wiedmann, 2014, Science, 6188: 1114-1117
- 5. Urban Water reuse and treatment is still virtually nonexistent in many areas ? Global Reuse: 1.7% (!) ? Treatment: Can be less than 2% in many areas (photo) Vrishabhavathi River in Karnataka State. Photo by AYALA CEO Eli Cohen ?? Dotan et al, 2016 Larsen et al, 2016 ?

- 6. Why is the Conventional approach not working? ? The Indian Institutes of Technology explain exactly why the conventional model failed in the Ganga River Basin (as a case study) ? Sprawling, failure-prone conveyance networks ? Reliance on energy, chemicals and skilled maintenance workers for function ? massive sludge production ? Frequent operational malfunctions due to high operating expenses and unstable energy supply (Tare et al, 2010, IIT GRB-EMP, report 3)
- 7. Change is the need of the hour The answer must include: ? A fast, simple solution to achieve full sewage coverage ? Minimal maintenance, energy, conveyance ? At the same time, water harvesting, aquifer replenishment and reuse capabilities ? Strengthening the ability of the environment to resist pollution and heal from within
- 8. AYALA’s comprehensive solution set: Solving the water- energy-pollution crisis and more ? Using decentralized systems to eliminate conveyance needs ? Restoring the natural assimilative capacity of the environment with green lungs and kidneys ? Treating sewage economically, efficiently and with no sludge production ? Eliminating the demands for energy and skilled, round-the-clock maintenance ? Harvesting, purifying and infiltrating run off ?
