Texas’ most populous cities lost roughly 88 billion gallons of water last year because of aging water infrastructure and extreme heat, costing them millions of dollars and straining the state’s water supply, according to self-reported water loss audits.
The documents show that bigger municipalities are not immune to water issues often seen in smaller, less-resourced communities around the state. All but one big city saw increased water loss from last year’s audits.
While cities are losing water because of inaccurate meters or other data issues, the main factors are leaks and main breaks.
Here’s how much each of Texas’ biggest cities lost last year, according to their self-reported audits:
- Houston: 31.8 billion
- San Antonio: 19.5 billion
- Dallas: 17.6 billion
- Austin: 7.1 billion
- Fort Worth: 5.9 billion
- El Paso: 4.8 billion
- Houston, San Antonio, Dallas, Austin, Fort Worth and El Paso must submit water loss audits to the Texas Water Development Board yearly. Other water agencies must do audits only every five years, unless the city has over 3,300 connections or receives money from the board.
“What we have right now is not sustainable [or] tenable,” said Jennifer Walker, National Wildlife Federation’s Texas Coast and Water Program director.
The cities of Houston and Dallas saw the biggest increase in lost water reported. Houston saw a 30% jump from last year’s audit, while Dallas saw an increase of 18%.
