IMPORTANT LIMIT

A leak can cause property damage beyond the utility charge. Shut off water and call a qualified professional for urgent leaks.

HOW TO USE IT

Copy the bill’s units first.

Match every field to the unit printed on your statement. Use the current billing period, preserve fixed charges, and compare a similar number of service days.

For a stronger estimate

  1. Use the exact rate from your bill instead of a reference average.
  2. Keep taxes, credits and past-due balances separate.
  3. Check tiers or time-of-use windows in the utility tariff.
