Residential Water Usage
Domestic water use depends on environment and culture.
The average person in the US uses 300L or 80 gal of water a day.
The average person in India uses only 41 L per day.
14
Industrial Water Use
Industry accounts for 19% of water use.
-Manufacturing goods
-Waste disposal
-Power generation
*Most water in industry is used to cool power plants
15
Power Plant Cooling Systems
1.Water is pumped from river or lake.
2.Water runs through pipes in cooling tower.
3.Water is pumped back into lake or river.
*Water is warmer than before, but usually clean. (Thermal Pollution)

Dangers of Dams
Harm river ecosystems: cause nutrients to be trapped on one side of the dam.
Displace ecosystems
Fail (may burst and flooding can occur)
26
WATER CONSERVATION
As water sources become depleted, water becomes more expensive.
27
Water Conservation in Agriculture
Water Conservation in Agriculture: water is lost through evaporation, seepage, and run-off.
•Solution: Drip Irrigation-water is delivered directly to plant roots.

Solutions for the Future
Desalination: removing salt from salt water.
Transporting Water: water transported from other regions.
-Water transported in huge plastic bags to dry places.
