Water Reuse: Converting wastewater to a useable resource

• A molecule of water can be reused five times

from release at Caballo Dam to Fort Quitman, Texas

• EBID and the Rio Grande Project have been

active in Water Reuse for more than 100 years

• Similar hydrology extends all the way to the

headwaters of the Rio Grande

• Most river systems do this to some extent

EBID Surface Water Allotment

• Reduced surface water allotment due to drought
• Increase of groundwater pumping by farmers
• Stormwater could be used as a potential source of water
• Field irrigation
• Aquifer replenishment
