2. Agave and Bradshaw • Irrigation • Plant watering systems • Landscaping • “Xeriscaping” • Water Harvesting • Collecting unused rain water

3. Problems • Non-desert vegetation • Chaotic watering system • No water harvesting • No records

4. Main Goals • Self sustained • Make areas enjoyable • Keep cost down • Eliminate waste

5. Irrigation Water Management

6. Why drip? • Almost no water loss due to wind or evaporation • Reduces weed growth • Reduce water use by up to 70% • Reduce cost of upkeep • Gov’t offers rebates to reduce cost

7. System Components • Rain sensor - $20 • Moisture sensor kit - $130 • Flow meter - $55 • ET Manager - $500

8. Installation Cost vs. Savings • Cost roughly 2.29$ per sq/ft to installif contracted out • Perimeter average about 4500 sqft and each courtyard roughly 5700 sqft, Approx. $21,000 to outsource • Without hiring out $50 per 20 plants • Sprinkler system to a drip system could save $70 per every $475. • No current record of water use. Future savings are unknown

10. Irrigation Controls Hunter IMMS

11. Electronic Controls • PC Based Software Package that makes central controls affordable, usable, and comprehensible • Graphically based command and control program • An optional ET program software that provides weather-based irrigation with soil moisture models that use inexpensive ET sensors.

12. Electronic Controls cont. • Full range of communications options, including Ethernet, GPRS mobile, dial-up telephone, UHF radio, and hardwired cables. • Application is compatible with Windows XP through Windows

13. Features • IMMS reports all alarms such as over currents and flow violations with individual date and time stamp messages. • Ability to create graphic map where you can see all the irrigation locations • Evapotranspiration system creates water saving system, can track climate history according to the sensors.

14. Landscaping Native plants Low water use plants Shade trees Grass Vs. Gravel

15. Main Courtyard • Mesquite • Red Bird of Paradise • Echinocereus

16. Main Courtyard cont. • Mesquite offers plenty of shade to lower temperature • Red Bird of Paradise is colorful shrubbery • Echinocereus adds color and iconic AZ cactus • All plants are low water use

17. East Courtyard • Planting area in shape of U.S. • Brick pavers separate regions • Each region depicted by plants from that area • Educational, enjoyable, low-cost

18. East Courtyard cont. • Southwest region: Autumn Sage • 2 feet tall - $20 • Northwest region: Harry Honeysuckle • 1 foot tall - $6 • Mid-west: Japanese Barberry • 4 feet tall - $50 • South east: Spicebush Shrubs • 5 feet tall - $40 • North east: Caroline Lupine • 4 feet tall - $25

19. West Courtyard • Desert botanical garden • Serve to teach about sustainable plants in AZ • Shaded via Mesquite • Revitalize an otherwise dismal area (Orange things not plants, just ideas for decorating)

20. Water Harvesting Collecting otherwise wasted rain water

21. Rain water Roof is roughly 47,400 square feet Chandler averages 9.27 inches Roughly 273,910 gallons a year goes unharnessed Enough water to sustain all plants

22. Harvesting System Stored until needed Water flows into temp. tank Pumped and filtered to main tank Excess water rerouted for other use Water taken as needed

23. Water Harvesting Materials • 1000 gallon tank - $489.99 – plastic-mart.com • 5000 gallon tank - $2,323.95 – plastic-mart.com • ½ horsepower, 10GPM pump w/ built in filter- $353.27 – plumbersstock.com • 1 inch diameter PVC pipe - $3.67 per 10 feet – lowes.com

24. Total Cost Low end cost estimate of $20,000 High end estimate $100,000 High estimate buys best of the best of everything Upkeep is reduced maximum amount
