Town of Manhattan:

Most homes outside these areas, even those in subdivisions, use private wells.  To learn more about regulations on well location in these areas, call the Gallatin County Environmental Health Department at (406) 582-3120 before contacting a well driller.

If the property you plan to build on is within a water and sewer district, you will be required to connect to that system.  It’s a good idea to check with your homeowners association for any specific rules or covenants pertaining to water wells on your property.

If your property is located within a Controlled Ground Water Area (CGWA), you will need to apply for a permit from the Montana Department of Natural Resources and Conservation (DNRC) to drill a well.
