Waste Water Waste water is water that contains waste from homes or industries.

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.

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.

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.

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.

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.

Major Irrigation Systems

Too Much Water

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.

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

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.
