Owner-operated water main, sewer line, and utility work for Rapid City, open 24 hours.
Rapid City is home. Our address is on Oakland Street, so a call across town is the shortest run we make, and we treat every one of them like it is next door.
On Site Excavating is based right in Rapid City, and Rapid City is squarely on our route. Being our home base, it is ground we know: the soil, the frost depth, the way water and sewer lines behave out here. That local knowledge is what separates a repair that lasts from one that fails again next winter.
For Rapid City homeowners, builders, and property owners, we handle water main repair & replacement, sewer line repair & replacement, new water & sewer installation, cistern & water service, excavation & trenching, and the excavation that goes with all of it. Whether it is an emergency main break at midnight, a failing sewer line, a new build that needs utilities run, or a cistern out in the foothills, you are dealing with the owner from the first call to the final cleanup.
Because we answer 24 hours a day, the owner is on the job, and the price is honest with no hidden costs. That is how On Site earned a perfect 5.0 across nineteen reviews, one straight-shooting job at a time. When your water or sewer goes down in Rapid City, you want a real person who owns the outcome.
Underground work in Rapid City means digging to proper depth below the frost line, bedding and backfilling right, and leaving the property clean. That is the standard on every job we run here, from a quarter-acre lot in town to acreage out toward the hills.
Leaking or broken water main lines located, dug up, and replaced fast, so your water is back on right.
