Water Usage

Facts From: http://www.epa.gov/watersense/about_us/facts.html


  • Water is a finite resource—even though about 70 percent of the Earth's surface is covered by water, less than 1 percent is available

  • for human use.

  • Forty out of 50 state water managers expect water shortages under average conditions in some portion of their states over the next decade.

  • Each American uses an average of 100 gallons of water a day at home.

  • We can all use 30 percent less water by installing water-efficient fixtures and appliances.

  • The average household spends as much as $500 per year on their water and sewer bill and can save about $170 per year by installing water-efficient fixtures and appliances.

  • A leaky faucet can waste 100 gallons a day.

  • An average bath requires 37 gallons of water. Take short showers instead of baths.
    A full bathtub requires about 36 gallons of water.

  • Each person needs to drink about 2 ½quarts (80 ounces)
    of water every day.

In The State of california the average water use is roughly 50% environmental, 40% agricultural, and 10% urban.

Water Distibution by Noa David

Water Distibution




Water Distibution is a big way we could consume and recycle water. Here are a few examples:


  • Freshwater is naturally occurring water on the Earth's surface on ice sheets, ice caps, glaciers, icebergs, bogs, ponds, lakes, rivers, and streams
  • Scientfically, freshwater habitats are divided into lentic systems
  • The source of almost all freshwater is Precipation from the atmosphere, in the form of mist

Water Distribution

  • The water Distibution on earth shows that most water in the Earth's atmosphere and crust comes from the world's ocean
  • The oceanic crust is young, thin, and dense with none of the rocks within it
  • The remainder of the Earth's constitutes the planet's freshwater resource

Methods for Preventing Water Usage in Companies by VanAnh Nguyen

4th Topic: Water Usage Solvents-

Focus Question: What methods can be taken to prevent high water usage? (relating to facilities and buildings)

by VanAnh Nguyen




  • EPA facilities have been upgrading their toilets and urinals with less gallons of water per flush (gpf); such as toilets= 1.6 gpf, urinals= 1.0 gpf or lower, etc.

  • Eliminate single-pass cooling: a process that circulates water once throughout a building for cooling purposes.

  • Xeriscaping is a new irrigation system used by planting water-efficient plants and obtaining techniques to decrease the amount of water used for irrigation.

  • Reverse osmosis: a process of generating deionized water that can be used purposefully; related to desalination.

  • Collecting rooftop rainwater, then using it for various purposes.

  • The process of air conditioning gives off condensated water from the cooling coils.

  • Some EPA laboratories use water for aquatic culture research; a solution would be to are reuse this water instead of dumping it into sewers or getting rid of it into lakes/bays.

  • A technique called "metering, measuring, and managing" could be used. Basically, measures of water throughout a facility are analyzed and if necessary, management of water will be needed.

  • Decrease the use of cooling towers: many companies/large buildings use "cooling towers" as a way of maintaining an adequate temperature in the area. However, these machines are large consumers of water.

  • Find ways for water-efficient irrigation. (such as manual irrigation, drip-irrigation, etc.)

  • Manage stormwater by slowing down runoff- let rain soak into lawns, rain collectors, etc.

Tips for Water Usage and Comservation by Prithvi Raj

Tips for water usage and conservation



1.Spend only 5 minutes in the shower
