Calculate Your Monthly Water Usage

Understanding Your Water Bill

Water rates for both residential and commercial customers are based on billing units (One billing unit = 748 gallons) and billing tiers. Please see information on your utility bill explained.

• 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.
• Water conservation is encouraged. Lower water usage will result in lower water bills.
