With DFW adding 200+ people per day, water supply is a real long-term concern.
Current water sources:
- DFW draws from multiple reservoirs: Lake Lewisville, Grapevine Lake, Lake Lavon, Lake Ray Hubbard, Richland-Chambers, and others.
- Major providers: Dallas Water Utilities, Fort Worth Water, North Texas Municipal Water District (NTMWD), Tarrant Regional Water District (TRWD).
- Source: twdb.texas.gov (Texas Water Development Board)
The math:
- DFW metro uses ~2 billion gallons of water per day.
- Population is projected to reach 10-11 million by 2050. Source: NCTCOG projections.
- Current water supply can handle growth until approximately 2050-2060 WITH conservation AND new projects.
What's being done:
- NTMWD — building new pipeline from Lake Texoma. $2.5B project. Source: ntmwd.com
- TRWD — Integrated Pipeline Project from East Texas. $2B+. Source: trwd.com
- Desalination — being studied for brackish groundwater in DFW area.
- Conservation — DFW cities have mandatory watering schedules (typically 2x/week). Source: savedallaswater.com
The worry:
- Drought years (2011 was devastating) can stress the system quickly.
- Climate projections suggest hotter, drier conditions for North Texas. Source: Texas State Climatologist.
- Pipeline projects take decades and billions of dollars.
What you can do:
- Follow your city's watering schedule
- Fix leaks (a dripping faucet wastes 3,000+ gallons/year)
- Xeriscaping (drought-resistant landscaping) reduces outdoor water use 50%+

Water policy is boring until the taps run dry. Pay attention.
