Dirt Work, Water Lines & Pipeline in Spearfish and the Northern Black Hills
Spearfish, Whitewood and Sturgis are a short haul from our St. Onge office. We bring pipeline-grade fusion and excavation to Black Hills homeowners, ranches and builders.
Pipeline Experience, Applied to the Black Hills
Northern Black Hills growth means new homes, shops and acreages that need water service, site prep and driveways. Ranches need stock water lines. Eaton Construction brings the same crews and equipment that build oilfield gathering systems to these projects, from a base minutes up the road in St. Onge.
What We Do in the Northern Hills
- Water service and stock water lines for acreages and ranches
- HDPE fusion for water and gas lines
- Excavation, grading and site prep for homes and shops
- Gravel hauling for driveways and pads
Communities We Serve
Black Hills Ground
Hillside lots, shale and limestone, and tight access are routine in the northern Hills. We size equipment to the site, plan spoil and access before we dig, and call South Dakota 811 at least 48 hours ahead of every excavation.

Black Hills 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.
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.
What do you need from me to put together a bid?
The location (legal description or GPS is ideal), the footage, the pipe material, diameter and pressure rating, any drawings or specs, crossings such as roads or other lines, and your target start date. Send what you have; we will ask for the rest.
Have a Line to Lay or Ground to Move?
Send us the scope: footage, pipe size and location. An owner will call you back.
