  4. Do you know where water goes after it flows down the drain? • Water goes through a series of sewage pipes and ends up in a waste water treatment plant. • At a waste water treatment plant, water is filtered and treated to make the water clean enough to return to a river or lake.

  5. Effects • In reality there is not that much water to be sparing. Rivers are drying up, aquifers are being depleted, fisheries are collapsing, and species are going extinct. • Gov. might have to raise the price of water in order to encourage water conservation.

  6. What do others have to say about this? • “According to water resource experts, the main cause of water waste is that we charge too little for water.” • “Subsidies keep the price of water so low that users have little or no financial incentive to invest in well-known water-saving technologies.” • Mohamed El-Ashry of the World Resources Institute estimates that 65-70% of the water people use throughout the world is lost through evaporation, leaks and other losses.

  7. Reducing Waste Water • We waste about two-thirds of the water we use but using water more efficiently could reduce wastage to about 15%. • Reducing waste water will decrease the burden on wastewater plants and reduce the need for expensive dams and water transfer projects that destroy wildlife habitats and displace people. • It will also slow depletion of groundwater aquifers and save energy and money.

  8. In order to waste less water in industries, homes, and businesses, we can: • Replace green laws and ornamental shrubbery with vegetation that needs little water; this is called xeriscaping. • Use drip irrigation. • Raise water prices. • Fix leaks. Mimic nature in dealing with wastes. • Use water-saving toilets and like appliances. Discontinue dumping industrial toxic wastes into municipal sewer systems.

  9. Major Irrigation Systems

  10. Too Much Water

  11. What Causes Flooding? • Heavy Rainfall , Rapid Melting of Snow, Removing Vegetation, Destroying Wetlands • Advantages of settling in floodplains: • Fertile soil, ample water for irrigation, availability of nearby rivers for transportation and recreation, and flat land suitable for crops, buildings, highways, and railroads. • Disadvantages of settling in floodplains: • Floods kill 25,000 people and cause tens of billions of dollars in property damage.

  12. Floodplain Diagram

  13. Case Study: Living on • Bangladesh has increased flooding because of upstream deforestation of Himalayan mountain slopes and the clearing of mangrove forests on its coastal floodplains. • Also contributing to floods: • Rapid Population Growth • Overgrazing • Unsustainable farming on steep and easily erodible mountain slopes

  14. Natural Capital • Forested Hillside • After Deforestation

  15. How can we help? • By controlling river water flows, preserving and restoring wetlands, identifying and managing flood-prone areas, and if possible choosing not to live in such areas. • We can use a method called channelization which means to straighten and deepen streams. • Another method is we can build levees or floodwalls along the stream sides. • The best suggestion: think carefully about where you want to live.
