Why is my water bill so high in San Antonio?
A practical, San Antonio-specific checklist: how your bill is built, what usually drives spikes here, and the quickest ways to find your fix.
How San Antonio Water System (SAWS) bills work
SAWS bills combine water supply, sewer, and aquifer-protection charges. Sewer charges are based on your winter water use, so leaks in December quietly inflate your bills all year.
Rates and schedules change — always confirm current numbers on the official San Antonio Water System (SAWS) site.
The usual suspects in San Antonio
- Winter leaks that lock in a high sewer average for the next twelve months.
- Summer lawn watering pushing usage into higher blocks during Stage drought restrictions.
- Pool evaporation in the Texas heat being mistaken for normal use (or hiding a real leak).
Fix leaks before the winter averaging window — it's the highest-leverage water move in San Antonio.
