  1. Water Conservation – Landscape And Drought Milan J. Michalec Cow Creek Groundwater Conservation District 09 August 2010

  2. Xeriscape In The Hill Country Does Not Mean Zero Color

  3. Hill Country Xeriscape Does Mean • Respect The Local Conditions • Balance The Landscape - 30% Turf/30% Hardscape/30% Plants • Plan For Drought • Consider Competition From Deer • Turf • Native Grass Such As Buffalo • Hardscape • Native Stone and Timber • Plants • Natives and Adaptive Species • Key: Go Native

  4. Typical Conditions

  5. Drought Conditions

  6. Drought In Texas • Hill Country • Long Periods of Drought Interrupted By Short Periods of Floods • Drought of Record • 1950-1957 (1954 Recorded 10. 29” Of Rain In Boerne) • Tree Ring Studies Indicate Far Longer And Drier Periods • Groundwater Pumping Can Only Be Managed By Local Groundwater Conservation Districts • Drought Contingency Plans Can Cut Pumping up to 50% for wells with operating permits • Wells used for Domestic and Livestock use are “exempt” from the operating permit process • Kendall County-Cow Creek Groundwater Conservation District

  7. Keep Plants Alive In Stage Five • Water Conservation Strategies • Condensate Recovery • Reuse Grey Water • Rainwater Capture • Take Inventory • Not All Plants Require Supplemental Water • Use Stored Water Sparingly • Apply Two Quarts Per Plant Every Third Day

  8. Put Away The Hose

  9. Condensate Recovery System Save Water Produced By Air Conditioner

  10. Typical Summer Daily Production 8-10 Gallons

  11. 1/3 HP Transfer Pump

  12. Condensate to Storage

  13. Reuse Grey Water • What Is Grey Water? • Any Water Used In The Home, Except Water From Toilets, Is Called Grey Water • Dish, Shower, Sink, And Laundry Water Comprise 50-80% Of Residential “Waste" Water • May Be Reused For Other Purposes, Especially Landscape Irrigation

  14. Typical Daily RecoveryDishes: 5 GallonsBathing: 3-5 Gallons Per Person

  15. Water Storage Remove Screw - On Top Remove Water With Bucket

  16. Rainwater Collection • 1” Rain On 1,000 Sq Ft Roof Can Yield 600 Gallons Of Water For Capture • Boerne Area Average Annual Rainfall • 33.74 (1893-2008) • Highest Annual Rainfall • 64.17 (1992) • Lowest Annual Rainfall • 10.29 (1954)

  17. Basic Rainwater Capture

  18. Improved Rainwater Capture

  19. Basic/Improved Collection • Shortfalls • Inefficient Capture • Insufficient Storage • Evaporation • Mosquitoes • Better Way? • Increase Capture and Storage • Seal Water From Elements

  20. 200 Square Foot Roof

  21. Install Gutters

  22. Increase Storage (1550 Gal)

  23. Add Collector Pipe

  24. Gravity Feed To Storage

  25. Sunlight Does Get Inside TankProblem: Algae Growth Solution: Paint Exterior
