Amarillo, TX is a mid-sized city, with a population near 198,645 and the 14th-largest community in Texas. Like much of Texas, Amarillo draws its water primarily from reservoirs, Ogallala aquifer, Edwards aquifer, and Rio Grande.
Amarillo's water outlook is shaped most by drought — the issue that dominates planning across Texas. Big Spring and Wichita Falls pioneered direct potable reuse in the U.S., and explosive growth plus recurring drought keep Texas at the center of reuse innovation.
Amarillo sits in a state that reuses roughly 16% of treated wastewater (established programs) and currently experiences moderate to severe drought.

Related water issues
Drought
Much of the American West is in a multi-decade dry period that researchers describe as the most severe in over a millennium, reshaping how communities plan for water.
ExploreGroundwater Depletion
Aquifers from the Central Valley to the Ogallala are being pumped faster than they recharge, causing land subsidence and threatening long-term supply.
ExplorePotable Reuse
Advanced purification turns treated wastewater into water that meets or exceeds drinking-water standards — increasingly essential in water-stressed regions.
ExploreAgricultural Demand
Agriculture accounts for the majority of consumptive water use in the West, making farm efficiency and water markets central to any supply solution.
