Penalty is assessed on the 17th and a late notice is mailed to all outstanding accounts. This notice serves as a cut-off notice and must be paid by the end of the month to avoid service disconnection and a $50 disconnect/reconnect fee.

For commercial accounts, the Application for Commercial Certificate of Occupancy and/or Water Service must be completed and approved by the Zoning, Building and Code Enforcement Departments before water service can begin.

After the Certificate of Occupancy has been issued, the water/sewer/garbage services can be connected upon receipt of deposit. Commercial deposits are dependent upon meter size and the City retains this deposit as long as the account is active. A driver’s license or photo identification must be presented at time of application or a copy may be included if sending in application by mail or fax.
