Water Bill Formula:
| From: | To: |
Submeter water billing allows individual unit measurement in multi-unit buildings, enabling fair cost allocation based on actual water consumption rather than fixed rates or square footage-based calculations.
The calculator uses the water bill formula:
Where:
Explanation: The formula calculates actual water consumption by subtracting previous reading from current reading, multiplies by the rate to get consumption cost, then adds any additional fees.
Details: Accurate submeter billing promotes water conservation, ensures fair cost distribution, helps identify leaks early, and provides transparency in utility charges for tenants and property managers.
Tips: Enter current and previous readings in gallons, rate in dollars per gallon, and any additional fees. Ensure current reading is greater than or equal to previous reading for accurate calculation.
Q1: What is the typical water rate per gallon?
A: Rates vary by location but typically range from $0.001 to $0.01 per gallon depending on local water costs and utility providers.
Q2: How often should meter readings be taken?
A: Monthly readings are standard for billing purposes, but quarterly readings may be used in some residential settings.
Q3: What if my current reading is less than previous?
A: This may indicate a meter reset, replacement, or reading error. Contact your utility provider or property manager for clarification.
Q4: What fees are typically included?
A: Common fees include service charges, infrastructure fees, administrative costs, and sometimes wastewater treatment fees based on water consumption.
Q5: Are submeters accurate?
A: Modern submeters are highly accurate when properly installed and maintained, typically within ±2% accuracy for residential applications.
