Title“The human right to water entitles everyone to sufficient, safe, acceptable, physically accessible 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)

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. diarrhea2. schistosomiasis3.trachoma4. infestation with ascaris5. infestation with guinea worm6. infestation with hookworm

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.

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

Texas & The Nation’s Historical Background to the Water Crisis•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.

Politics •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

Political Consequences (cont.)

•W A R

Economic•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.

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

Who Suffers?•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

Who Suffers ?

• Millions of people worldwide• Agriculture• Ranchers• Businesses• Wildlife• YOU !!

Who benefits economically?•Government and politicians

•Less supply more demands which includes a high price in markets

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.

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

Map of the World showing water scarcity

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 Basin4. San Antonio, TX- Various groundwater sources5. San Francisco bay areas- Various, including Lake

Hetch Hetchy6. Fortworth, TX- Multiple water supplies7. Las Vegas- Lake Mead/Colorado River8. Tucson, AZ- Local groundwater9. Atlanta- Lake Lanier10.Orlando, FL- Florida Aquifer

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.”

***Coming Soon – Desalination Plant***

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

Possible Solutions (cont.)!!!•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.

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
