A property may be connected to the City's water system if it is located within the City limits and utilities are available. If utilities are not already stubbed to the property line, an Encroachment Permit is needed to work in the City right-of-way. Contact the Engineering Division to determine the closest utilities and availability for connection. A Building Permit is also required to construct utilities from the property line to the house and may be obtained through the Building Division. Connection Fees are collected when the Building Permit is issued.
