Drought the new normal
Drought – the new normal?

  • 2011 – worst 12 month period of drought recorded in Texas history

  • Agriculture - $5 billion lost

  • Wildfires

  • Reservoirs down to 60% of water storage levels

  • More than 900 of the state’s 4700 water supply systems had water restrictions

  • February 2014 – officially back in drought in Houston

  • -data from Lone Star Sierran Fall-Winter 2011

5 ways to increase water availability
5 Ways to increase water availability

  • Build more dams – use more surface water

  • Use more groundwater - aquifers

  • Transfer water from other places

  • Desalinate water

  • Conserve water

Desalination get the salt out
Desalination – get the salt out!

  • How it works – three systems

    • Reverse osmosis

    • Freezing salt water – ice will be fresh

    • Distillation – boiling, then trapping the fresh steam

Being smart with the water we already have.

Conservation success
Conservation success

  • San Antonio – pumps no more water today than it did 20 years ago, despite the dramatic population increase in its service area in that same period of time!

  • Thanks to conservation!

  • San Antonio reduced its per capita use by more than 70 gallons.

What about recycling water grey water

  • Grey water is being used more in:

    • Golf courses

    • Sweeping streets

    • Fighting fires

    • Parks

    • Amenity lakes

Current texas water reuse 2
Current Texas water reuse 2% reaches plant roots

  • New technology cleans water to almost distilled quality

  • Eventually, 10% of water demand will come from reuse in Texas

Tradeoffs! reaches plant roots

  • Reuse will divert more water from rivers.

  • Less water downstream for people and wildlife

  • Before:

    • River  home  river

  • After:

    • River  home  land

  • Saving water at home

    Saving water at home reaches plant roots

    What can you do directly?

    • What kind of behaviors in the home can conserve water?

    Check for understanding

    • Why is conservation considered the easiest way to increase the amount of water available for use?

    • What is the name of the wasteful agricultural irrigation system?

    • Name a way to save water in agriculture.

    • Name a way to save water at home.

    • How are YOU responsible for the amount of water used in industry?

    • What is grey water?
