3 Big Ideas to Make Water Last

Steward our watersheds, share the water fairly, and live within our means. Here is what sustainability looks like:

The “Watershed Moments” article in the Summer 2010, ‘Water Solutions’ issue of YES! Magazine.

Only a tiny fraction of Earth’s water is available as fresh water.

We’re already at the limits of supply in parts of the United States. But even with climate change and growing populations, there’s enough for everyone if we work together to keep it clean, use it wisely, and share it fairly.

Where is our water?


poster_wave.jpg95.7% of the water on earth is salty. 84% of water in the atmosphere comes from the oceans, than falls as rain.

Of the 2.5% of Earth's water that's fresh, about 70% is ice—and inaccessible. [1]

Of the 2.5% of Earth's water that's fresh, about 30% is groundwater. [2]

Of the 2.5% of Earth's water that's fresh, 0.3% is surface water (in lakes, rivers, and wetlands) or water vapor. [3]

3 big ideas to make water last

Take care of the ecosystems that supply us.


  • poster_fish.jpgLower CO2: Mountain snowpacks are shrinking because of climate change. About 75% of the water supplies in the western United States come from snowmelt.
  • Restored wetlands: Clean watersheds save cities billions compared to the cost of water purification plants. New York City is saving $6.5 billion by restoring the Catskill-Delaware watershed. [4]
  • Animal engineers: Beaver ponds slow runoff, letting water percolate into aquifers. Prairie dog tunnels help water soak into the ground.
  • Wild rivers: Naturally meandering rivers reduce erosion, create wildlife habitat, and slow flow, allowing surrounding soil to soak up more water.
  • Refilling aquifers: Groundwater is replenished by surface water, but slowly. Parts of the Ogallala Aquifer recharge at a rate between 0.07 and one inch per year.
  • Rain-friendly design: Porous pavement, rain gardens, and swales let rainwater seep into the soil, rather than overwhelming storm drains.

  • Organic fertilizers avoid toxic runoff to rivers and keep fish stocks healthy.
  • Clean Water Act: Watchful Waterkeeper programs and community activists use laws to keep industrial neighbors clean.
  • Protect the commons: Clean and wild waterways allow for both healthy wildlife and human recreation.

Learn to live within our water means.


  • poster_island.jpgWind and solar: Solar panels and wind require little water to generate electricity. Thermoelectric is our single biggest water user.
  • Organic farming methods boost the ability of soil to hold water.
  • Drip irrigation saves up to 50% compared to overhead sprinklers. [<a title=""Drip irrigation typically saves between 30-50% of water used on crops and orchards." extension.osu.edu/%7Enews/story.php?id=481" href="#-drip-irrigation-typically">5</a>]<br /></li><li><strong>Native plants:</strong> We use 9 billion gallons of water a day on lawns and golf courses. Native plants require little irrigation.

Reclaimed wastewater contains beneficial nitrogen and phosphorus for plants.</li><li><strong>Save the rain:</strong> Annual rainfall on Los Angeles is equal to two-thirds of the water the city uses each year.
