If you reside within the City limits, there are probably water and sewer facilities available to your property, but sometimes there are exceptions. Recent annexations or old property subdivisions sometimes create “pockets” where extensions are required.
The CCU will work with you in extending facilities to your site if this is the case, but extensions can take time. If you suspect that facilities are not available, it would be to your benefit to contact the CCU Engineering department as soon as possible.
