The District requires permanent water mains be installed either within the City or County right-of-way, or within an easement dedicated to the District. If you live on a private road, and the developer’s property is also on that private road, the water main may be constructed on that private road and the District will require an easement for the water main.
In any event, the actual location of the water main can only be determined during the project design. Water mains may be located under paved or gravel roads and shoulders or outside of roads. Number permanent structures may be constructed over the water main, although, you may have a fence crossing the main.
