Account responsibility

  • All water meters in the Town are read for actual usage the first three days of the month and bills are generated and mailed between the 6th and 9th of the same month.
  • All payments are due on the last business day of the month. Payments received after the 5-day grace period will be assessed a $5 late fee. If a past due balance remains on the account, customers may receive a Notice of Intent to Disconnect Water, with additional service fees.
  • Upon disconnection due to non-payment, service reconnection requires all charges due be paid in full. (Municipal Code 13.14.070) Once full payment is received in our office, service will be scheduled for reconnection by the end of the next business day.
  • It is the responsibility of the property owner to ensure payments are made in full every month (by their tenants) to avoid a disconnection or possible property lien.
