Calculate Your Monthly Water Usage
Last months's reading - This month's reading = Monthly usage
Understanding Your Water Bill
Water rates for both residential and commercial customers are based on billing units (One biliing unit = 748 gallons) and billing tiers.
-
Reference the appropriate customer sections below for calculation details.
-
Each tier builds on the preceding tier, so your water bill is commensurate to your water use.

Residential Customers
-
The first three (3) units of usage per month will be billed at the lowest tier 1 rate.
-
If your usage exceeds three (3) units but is less than twenty-five (25) units, these additional units will be billed at the tier 2 rate.
-
If your household uses more than twenty-five untits or 500 gallons of water a day, you may fall into all three tiers.
- A single 3/4 inch or 5/8 inch meter serving multi-residential units will pay the rates listed for twice the amount of water.
- The flat meter charge for a 3/4 inch and 5/8 inch meter is an additional $5.05 per month.
The first three (3) units of usage per month will be billed at the lowest tier 1 rate.

Commercial Customers
As a Mountain View customer with a one inch meter or larger, you are billed for the water you use according to an inverted rate structure which means your water bill is commensurate to your water use.
In a progressive rate structure, high water users pay more for a unit of water than those who conserve and keep their water use down.
