The landlord may sub-meter, in which each tenant is billed for their usage based on actual meter reads. This is the preferred method of sub-billing.
EXAMPLE
Sunny Side Apartments has 100 apartment homes, and the complex gets one water bill per month from the city. Each month, the landlord or association calculates the rate for all of the households based on total water charges and usage. If a resident’s sub-meter measured 3,500 gallons for April, they would be charged the calculated rate for each gallon used that month.
SAMPLE CALCULATION
Master water charges total $5,000 for the consumption of 4,000 CCF (approx. 3,000,000 gallons). This includes tax, fire protection, base fees, and usage. Sample resident usage in this example is 3,500 gallons.
Step 1. $5,000 total bill divided by 4,000 CCF for that bill, then divided by 750 (there are 750 gallons per CCF) = $0.001667 per gallon
Step 2. $0.001667 multiplied by sample resident’s 3,500 gallon usage = $5.83 total water charges
