Hidden Leak / Water Waste Calculator
A leak rarely announces itself with a number. This calculator turns “the valve won’t fully close” or “there’s a wet spot even when nothing’s running” into an actual dollar estimate, using Hernando County Utilities’ own current tiered water rate rather than a generic national average.
The starting point is one extra zone cycle a day for about a month, priced at a mid-usage rate tier. Two things move it a lot: how bad the problem actually is, and how long it has been going on, both of which you set with the dropdowns above.
Why the tiered rate matters more than it seems
Hernando County Utilities bills residential water in seven usage tiers, and the rate per 1,000 gallons roughly triples from the lowest tier to the highest. A household that normally sits in the second or third tier, and then runs a stuck-open zone for a month, does not just pay for the extra gallons at the rate it was already paying. It very often gets pushed into a higher tier for the whole month, which means the higher rate applies to gallons the leak did not even use. That is the honest reason a “small” leak can show up as a surprisingly large jump on the actual bill.
Reading the result honestly
This number is water cost only. It does not include the repair itself, sewer charges tied to water usage on some bills, or the cost in pump wear if your property irrigates from a private well rather than a county meter, which is common across a lot of Spring Hill and Hernando County given the county’s own policy against new residential irrigation-only meters since 2004. What it does show clearly is the trade: almost any valve repair or line repair costs less than a month or two of a leak left running, often considerably less.
If you are not sure yet whether what you’re seeing is actually a leak, the water bill spike problem page walks through how to confirm it before booking a repair. And if what you actually want is a repair cost rather than a waste estimate, the sprinkler repair cost calculator answers that instead.
What is this leak actually costing me?
Three questions. The starting number is one extra zone cycle a day, priced at Hernando County Utilities' own current tiered water rate. Change the severity and how long it has been running to see how fast a small leak adds up.
Built from Hernando County Utilities' own published rate tiers: this fiscal year's residential rate runs from about $1.87 per 1,000 gallons in the lowest tier past $11 per 1,000 gallons in the highest. A leak large enough to push your whole month's usage into a higher tier costs more than a simple gallons-times-average-price estimate would suggest, because the higher rate applies to all the gallons in that tier, not just the extra ones.

Frequently Asked Questions
Where does the water rate come from?
Hernando County Utilities' own published rate schedule for a 5/8 inch standard residential meter, current fiscal year: $1.87 per 1,000 gallons in the lowest tier (0 to 5,000 gallons), climbing through $2.29, $3.66, $5.50, $7.90, and $11.22 per 1,000 gallons at higher tiers, up to $15.46 per 1,000 gallons over 75,000 gallons, plus an $11.28 monthly base charge. Rates step up again each October under the county's multi-year rate schedule.
Why does a leak cost more per gallon than my normal usage?
Because Hernando County bills in tiers, and every gallon in a higher tier costs more than every gallon in a lower one. A leak large enough to push your total monthly usage from, say, the second tier into the fourth or fifth tier means the higher rate applies to a much bigger share of your bill, not just the extra gallons the leak itself used.
Does this include what I'd pay for a repair?
No, this calculator only estimates the extra water cost from the problem continuing. Repair costs are separate and are on the pricing page: valve repair runs $150 to $350, lateral line repair $100 to $300, and mainline repair $200 to $600.
I have a private well, not a county meter. Does this apply to me?
Not directly. A private well doesn't bill by the gallon the way a county connection does, so a leak on a well-fed system costs you in pump wear and, if the well ever struggles to keep up, water pressure, rather than a metered dollar figure. The repair itself is priced the same either way.
