Annual Toilet Water vs Water Rate
Formel
## How to Calculate Toilet Water Usage Toilets are the single largest indoor water user, accounting for about 24% of household water. ### Formula **Annual Gallons = Flushes/Day * GPF * 365** ### Gallons per Flush by Age - Pre-1980 toilets: 5-7 GPF - 1980-1994: 3.5 GPF - 1994+ federal standard: 1.6 GPF - WaterSense (current): 1.28 GPF - Ultra low-flow: 0.8-1.0 GPF
Lösungsbeispiel
12 flushes/day with 1.6 GPF toilet at $5/1000 gal water rate.
- 01Daily water: 12 * 1.6 = 19.2 gallons
- 02Annual water: 19.2 * 365 = 7,008 gallons
- 03Annual cost: 7,008 * $5 / 1,000 = $35.04
- 04Savings with 1.0 GPF: (1.6-1.0) * 12 * 365 * $5 / 1,000 = $13.14
Häufig Gestellte Fragen
How many times does a person flush per day?
The average person flushes about 5-6 times per day. A household of 2-3 people averages 10-15 flushes daily.
How much can a low-flow toilet save?
Replacing a 3.5 GPF toilet with a 1.28 GPF model saves about 9,700 gallons per year for a typical household, cutting toilet water use by 63%.
Do dual-flush toilets save water?
Yes. Dual-flush toilets use 0.8 gallons for liquid waste and 1.6 for solid. Since most flushes are for liquid, average use drops to about 1.0 GPF effectively.
