Frequently Asked Questions
Where do I find my price per 1,000 gallons?
Check your water utility bill or rate schedule — rates are often tiered, so this calculator uses a single average rate for simplicity.
Does this include sewer charges?
No — many utilities bill sewer service based on water usage as a separate line item. Add that rate separately for a fuller picture of your total bill.
