Belle Fourche & St. Onge FAQs
Do you install rural water or stock water lines for ranches in western South Dakota?
Yes. From our St. Onge base we install poly water lines, service connections and stock water lines for ranches, landowners and rural water systems in Butte, Lawrence and Meade counties. The same fusion equipment and crews that build our oilfield lines build yours.
How deep do water lines need to be buried in the Dakotas?
Deep enough to stay below frost. In western North Dakota, water lines are commonly buried 7 to 8 feet; in western South Dakota, 5 to 6 feet is typical. Your engineer, rural water system or county sets the exact spec, and we build to it.
Do I need to call 811 before digging in North Dakota or South Dakota?
Yes. Both states require a locate request at least 48 hours before you dig, not counting weekends and holidays — North Dakota One Call and South Dakota 811 both take requests by phone at 811 or online. On our jobs, we place the locates and verify marks before any equipment breaks ground.
