4. “The human right to water entitles everyone to
sufficient, safe, acceptable, physically accessible
Title
and affordable water for personal and domestic
uses. An adequate amount of safe water is
necessary to prevent death from dehydration,
reduce the risk of water-related disease and
provide for consumption, cooking, personal and
domestic hygienic requirements”.
(General Comment 15, CESCR, 2002)

5. Global Facts
…the reality is…
•more than one out of six people lack access to safe drinking water;
1.1 billion people
•more than two out of six lack adequate sanitation;
2.6 billion people
•3900 children die every day from water-borne diseases
•Up to half of humanity has one of these six main diseases
1. diarrhea
2. schistosomiasis
3.trachoma
4. infestation with ascaris
5. infestation with guinea worm
6. infestation with hookworm

6. Social Consequences Globally
• China, with 1.26 billion people, "the water table is dropping one
meter per year due to over-pumping, and the Chinese admit that 300
cities are running short.
• In India, home to 1.002 billion people, key aquifers are being over-
pumped, and the soil is growing saltier through contamination with
irrigation water
• Israel (population 6.2 million), invented many water-conserving
technologies, but water withdrawals still exceed resupply.
• Egypt (population of 68 million), is irrigated by seasonal floods from
the Nile River, and from water stored behind the Aswan High Dam.
Any interference with water flow by Sudan or Ethiopia could starve
Egypt.
• Mexico City (home to 20 million people) is sinking because the city
sucks out underground water faster than the aquifer can be refilled.

7. Social Consequences (cont.)
• More and more areas are becoming unstable
with regards to their water resources
• More and more people are dying from thirst
and water-borne contaminants

8. •The 1950s drought severely impacted a 1.1millionkm2 area in the central US.
This drought, along with the famous 1930s drought, was among the most severe
of the 20th century for large areas and is the drought of record for water supply
planning in Texas.
•The total annual dependable water supply in Texas is approximately 16.3
million acre-feet.
•Texas has had an abundance of natural resources, although it has had some
cases of really severe drought.
• 95% of the united states fresh water is underground, and farmers in the Texas
High Plains pump groundwater faster than rain fills it, and the water tables are
dropping.

9. •Over 50 percent of all water projects fail and less than 5 percent of
projects are revisited and far less than one percent are monitored.
•New approaches to long-term water planning and management
that incorporate principles of sustainability and equity are required
and are now being explored by national and international water
experts and organizations.
•Politicians have proposed many different methods to this major
topic, among these principles are guaranteed access to a basic
amount of water necessary to maintain human health and to
sustain ecosystems, basic protections for the renewability of water
resources, and institutional recommendations for planning,
management, and conflict resolution

10. Political Consequences (cont.)
•W
A
R

11. •For each one dollar invested in the World Health Organization
it is estimated that $3-$34 of services are possible in developing
countries depending on the region and technology.

12. Economic Consequences of
diminishing water resources
• Higher food prices at the supermarket
• Loss of businesses (old and new)
• Higher cost for water on your utility bill

13. •Us humans of course no water, no life! The more population the less
water. As mentioned, about 1.1 billion people lack access to clean
water, and 2.6 billion do not have access to improved sanitation
facilities
•Destruction of aquatic ecosystems and extinction of species
•Growing risks of regional and international conflicts over scarce or
shared water supplies
•Businesses- (cost of water); both surface water and groundwater in
response to high market prices

14. Who Suffers ?
• Millions of people worldwide
• Agriculture
• Ranchers
• Businesses
• Wildlife
• YOU !!

15. •Government and politicians
•Less supply more demands which includes a high price in
markets

16. Who Benefits from Clean Water?
• EVERYONE !!
• If ever there was something that people
actually “can’t live without”, it is water.
• Not just any water, but clean, drinkable water.

17. What Conditions Help To Promote The
Problem ?
• “Can’t happen here” mentality; denial that
there is a problem
• Population growth- coupled with
industrialization and urbanization
• Climate change
• Lack of environmental concern; pollution
• Lack of conservation; misuse

18. Map of the World showing water scarcity

20. Top 10 largest cities by population that have the greatest chance
of running out of water
1. Los Angeles-major water supply Colorado River Basin
2. Houston- Jasper Aquifer, Lake Houston, Lake Conroe
3. Phoenix- Colorado River Basin
4. San Antonio, TX- Various groundwater sources
5. San Francisco bay areas- Various, including Lake Hetch
Hetchy
6. Fortworth, TX- Multiple water supplies
7. Las Vegas- Lake Mead/Colorado River
8. Tucson, AZ- Local groundwater
9. Atlanta- Lake Lanier
10. Orlando, FL- Florida Aquifer

21. Local Perspective
• A Brief History of Water in San Antonio.
• Edwards Aquifer Authority Established
• Tom Gallier, Bx. Mets Interim Gen. Mngr. said,
“There is no single land issue that is more
critical than water.”
• Top 200 water users in June 2011

*** Coming Soon – Desalination Plant***

25. Possible Solutions
• 1st step to any solution is in getting people to
understand that there is a problem
• Need to work to keep the water we do have
clean; reduce contaminants

26. •Water conservation methods such as replacing existing toilets with
low-flow toilets
•The use of grey water (all the waste water that drains out of your
washing machine and sinks), it can be easily treated and recycled.

27. Still more possible solutions:
1. Hard path
- building of dams, pipelines & environmentally-destructive
infrastructure
- government run and owned with no personal ownership
2. Soft path
- Reuse of wastewater ~ storm runoff, gray water & reclaimed
wastewater are well-suited to irrigate landscaping
- water agency or company personnel to interact closely with water
users & to engage community groups in water management.
- governments, companies, & individuals to meet the needs of
peoples & businesses, instead of just supplying water
3. Privately funded companies
4. Desalination - the removal of salt from salt water -- would be the
ultimate solution to water woes -- if it can be done cheaply enough

Individual Actions Matter
