1. Comisión de Cooperación Ecológica Fronteriza Border Environment Cooperation Commission Elephant Butte Irrigation District North American Development Bank Elephant Butte Irrigation DistrictWater Conservation ProjectPipe Installation on Unlined Earthen Laterals

2. Project Description • 20 Laterals • 15.0 Miles of Pipeline • Arrey System • Leasburg System • Mesilla System • 48” UltraFlo Pipe • 3-Year Construction Schedule

3. Selection Criteria Identified as “problem areas” due to: • High seepage • High maintenance • Weed growth • Ditch breaks • Low capacity • Increase to maintain approx 35-40 cfs • Encroachments • Minimal Environmental Impact

7. Project Benefits • Water Savings • Reduced Maintenance • Environmental Enhancement • Public Safety

8. Project Benefits • Water Conserved • Almost 3.25 billion gallons (10,000 acre-feet) of water per year due to reduced seepage • Equivalent to irrigating • 2,500 acres of Pecans • 4,000 acres of Cotton • Providing Municipal water to service • 180 gal/day a population of 50,000

9. Project Benefits • Reduced Maintenance Costs • not mowing 15 miles of piped laterals • Labor for mowing • Herbicides • Less wear and tear on equipment • Less weeds seed on fields • Farm savings due to less herbicide application • Eliminate weed plug

10. Project Benefits • Environmental Enhancements • Less use of Herbicides • Protection from illegal dumping into open ditches • Fewer contaminants to water from soil erosion and wind-blown debris • Reduced Dust • Less travel on canal banks from EBID equipment for maintenance and operations • Multiuse development • Trails, walkways, bike paths, etc.

11. Project Benefits • Public Safety • Reduced danger of accidents involving vehicles and/or people • Reduced water contamination • Reduced liability risks
