Calculate the cost of replacing a known amount of pool water.
This calculator estimates the cost of replacing pool water from the amount of water added and the rate charged by your utility. Enter the refill volume, choose the billing period, and select whether your water rate is listed per 1,000 gallons, per CCF, or per gallon.
The calculator shows the cost for the selected period and converts it to an approximate monthly amount for easier comparison.
Pool water loss can come from evaporation, splash-out, backwashing, leaks, draining, or automatic-fill operation. Tracking refill cost helps reveal how much water the pool is actually using and whether that usage seems reasonable.
A sudden increase in water use may point to a leak, a stuck auto-fill valve, an overflow problem, or unusually high evaporation.
Many utilities bill water by the thousand gallons or by CCF. One CCF equals about 748 gallons. Some bills also include sewer charges, service fees, or tiered rates, which can make the real cost higher than the simple water rate alone.
You can use a flow meter, utility meter reading, hose-flow estimate, or timed refill calculation. A dedicated water meter gives the clearest result.
It can. Because the water level stays constant, a leak may show up only as higher water use or a rising bill.
Include them when your utility charges sewer fees on pool-fill water. Some areas offer adjustment programs for pool filling, but policies vary.
Normal evaporation depends on weather, wind, humidity, water temperature, and cover use. Compare actual refill volume with local evaporation conditions before assuming a leak.
If the auto-fill keeps the level perfect, watch the water bill instead. A hidden leak can look like a well-behaved pool.
