Water usage increased during watering season, especially after a controller change, yard work, broken head, or unusually wet spot.
Irrigation leaks can waste water quickly because outdoor systems often run at high flow. A stuck valve or broken line may move the bill into higher water tiers.
Check first
Inspect sprinkler heads, valves, wet spots, and runoff during a cycle.
Check controller start times, run times, and rain sensor settings.
Compare daily gallons on watering and non-watering days.
Look for higher-tier water rates after outdoor usage increased.
Practical savings moves
Fix broken heads, stuck valves, and leaking lines promptly.
Reduce duplicate start times or unnecessary zones.
Use irrigation cost math before changing indoor habits.
Track gallons after repairs to confirm the bill driver is gone.
Avoid these mistakes
Do not assume a high outdoor bill is normal summer use without checking the system.
Do not ignore tiered water rates that make extra gallons more expensive.
Do not confuse irrigation water with sewer unless your utility bills it that way.
