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.
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

Technology overview
• Tailored, engineered Natural Biological
System™ wetlands, based on thorough survey
• Point and non-point source pollution
remediation: sewage treatment, runoff
harvesting & purification, river and lake
buffering, running water upgrade, aquifer
replenishment.
• Powerful, non-toxic plant-sourced extracts for
stimulating plant and microbe metabolism
• Biological degradation of sludge, removal of
biological odours- treatment of water bodies in-
situ and at no/minimal energy expenditure

• Onsite
• No energy costs
• Minimal conveyance infrastructure
• Viable, high-quality outlet
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

Press and Testimonials“After experiencing the results of the system, we are
strongly promoting this technology to Government
organizations, Industries, corporates & educational
institutions to implement this sustainable solution for
treatment of waste water.” – S Ragupathy, Executive
Director, Indian Green Building Council, Godrej-CII
“More such initiatives are needed in the city as there
are a lot of problems being faced by people. The
department will take into consideration and work
towards implementing it wherever required to give
citizens pure and healthy water.” BJ Reddy, GHMC
Commisioner (Hyderabad)
“Operation of this system has put an end to former free
discharge of raw sewage to the environment and treated

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
Hyderabad Golf Course- in Musi Catchment
• Hyderabad Golf Association

• Surface water in the area is
abundant but highly
contaminated
• HGA is also mandated with
