The bill shows Tier 1, Tier 2, block, inclining block, conservation rate, or higher prices after a usage threshold.
Tiered water rates make extra gallons more expensive after a threshold. Outdoor watering or a leak can raise the bill faster than a simple average rate suggests.
Check first
Find tier thresholds and rates for water usage.
Compare gallons or CCF against the tier breakpoints.
Check irrigation, pool top-offs, guests, toilets, and leaks.
Separate sewer and fixed fees from tiered water usage charges.
Practical savings moves
Target high-tier usage first when changing watering or leak repairs.
Use irrigation and leak calculators to estimate the driver.
Track daily gallons after repairs or schedule changes.
Use water savings math based on the tier affected by the reduction.
Avoid these mistakes
Do not value every saved gallon at the average rate if high-tier gallons are involved.
Do not ignore sewer charges that may also follow water use.
Do not compare months without normalizing billing days.
