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.

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

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)

• The environment is

suffering and humans

are too…

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)

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

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

• Restoring running and standing waterbodies

with a combination of ecologically viable,

sustainable and safe techniques

Summary

• Massive and on-going environmental damage in disturbed environments can often be

traced to the difficulty in implementing a sustainable solution for pollution treatment and

control.

• With AYALA’s NBS, sewage treatment, water harvesting, environmental buffering and

ecological restoration can be implemented in a single, easy-to-manage, highly economical

package

• AYALA provides a unique and holistic vision for water resource management that

connects and revitalizes entire river basins and watersheds, restoring balance through

Nature’s own techniques

Case Study: Musi River Catchment, Hyderabad

MUSI RIVER

HUSAIN SAGAR LAKE:

THE “HEART” OF HYDERABAD

• Polluted nalas carrying industrial and domestic sewage

• Lack of clean surface water

• Stagnant lakes

• Dense urban environment with no room for centralized

STPs

• Conveyance outside the city is costly and impractical

Current State

The path to rehabilitation must include

• Onsite treatment of nallas and sewage

• Buffering of lakes and rivers from incoming sewage

• Treatment of the watershed in a holistic, connected

manner, respecting the catchments and overflow

routes of the many water tanks
