How Much Is That Leak Costing You? (Suburban Water Systems Rates)
See what a dripping faucet, running toilet, or sprinkler leak costs on real Suburban Water Systems tiered rates for La Mirada homes.
Call (562) 488-9614Most online drip calculators use a generic national water rate that has nothing to do with what La Mirada homeowners actually pay. This one uses current Suburban Water Systems tiered rates for the Whittier and La Mirada service area under Schedule WLM-1, regulated by the California Public Utilities Commission. The cost shown is accurate for local homes because it accounts for the tier structure: monthly usage above the break point is charged at a higher rate per CCF than baseline use.
Southern California conservation pricing means that a leak does not just cost the base rate for the water it wastes. If the leak is large enough to push your total monthly consumption above the tier break, every CCF you use for normal household purposes also ends up in the higher tier. This tool calculates the full cost impact, including the tier stacking effect on your Suburban Water Systems bill.

Understanding the cost
Why Southern California Leaks Cost More Than Generic Calculators Show
The difference between Suburban Water Systems tiered billing and a flat national average is substantial for homeowners with active leaks. Under Schedule WLM-1, baseline monthly residential usage up to the tier break is charged at the Tier 1 rate. Usage above that point costs more per CCF. A running toilet wasting 480 gallons per day adds approximately 14,600 gallons per month, well above 19 CCF, pushing a significant portion of that volume into the higher tier.
The tier stacking effect means that if you already use 10 CCF per month for normal household purposes and a toilet leak adds 8 more CCF, the full 8 CCF of the leak land at the higher Tier 2 rate, not the baseline rate. This is why the cost shown in this calculator is typically higher than a generic calculator would predict for the same drip rate. The Southern California water pricing structure is designed to discourage high consumption, and a leak is indistinguishable from intentional consumption to the billing system.
Dripping Faucet vs Running Toilet vs Irrigation
A dripping faucet at 60 drips per minute wastes roughly 5 gallons per day, which adds up to about 150 gallons per month. In isolation, that is a small bill impact. A running toilet at 480 gallons per day adds nearly 14,600 gallons per month. At Suburban Water Systems rates, those two are in entirely different cost categories despite both appearing as minor household leaks to a homeowner who hears no obvious sound.
An irrigation zone that fails to close adds the highest volume of any common household leak type: a single 60-gallon-per-hour zone running continuously adds over 43,000 gallons per month. Beyond the water bill, outdoor irrigation leaks can saturate the soil around the foundation, contributing to the kind of ground movement that stresses slab supply lines. See the irrigation leak detection service page for what that looks like on the ground.

Common questions
Questions About Leak Costs in La Mirada
How much does a dripping faucet cost per year in La Mirada?
At a steady 60 drips per minute, a dripping faucet wastes about 1,800 gallons per year. On Suburban Water Systems Schedule WLM-1 rates, that adds approximately $5 to $12 per year depending on whether the added volume pushes you into the higher tier. The real cost of a dripping faucet in La Mirada is usually the compounding effect when combined with other use, not the drip in isolation.
What are Suburban Water Systems rates for La Mirada?
Suburban Water Systems serves La Mirada under Schedule WLM-1, regulated by the California Public Utilities Commission. The schedule uses a tiered rate structure with a fixed monthly meter charge plus per-CCF quantity rates that increase above the tier break. Confirm the current rate values from a recent Suburban bill or the CPUC tariff sheet at swwc.com.
How much water does a running toilet waste?
A typical running toilet with a failed flapper wastes 200 to 700 gallons per day, with 480 gallons per day being a commonly cited average for a fully running toilet. At 480 gallons per day, the annual waste is approximately 175,000 gallons, or 234 CCF. At Suburban Water Systems rates, that volume pushes well into the higher billing tier and can add hundreds of dollars per year to your bill.
Does a leak raise my bill to Tier 2 in Southern California?
It depends on your household baseline and the leak size. A running toilet or a significant irrigation leak almost always pushes total monthly usage above the tier break into the higher tier. The calculator above accounts for this by stacking the leak volume on top of a typical 8 CCF monthly household baseline before applying the tier structure.
