Questions, answered straight

What folks around Rapid City ask most before they call. Still have a question? Call or text (605) 430-2626, day or night.

Are you really open 24 hours?

Yes. On Site Excavating is open 24 hours a day, 7 days a week. Water and sewer emergencies do not wait for business hours, so we do not either. Call or text (605) 430-2626 any time and you will reach us.

What does On Site Excavating specialize in?

Water and sewer utility work. Water main repair and replacement, sewer line repair and replacement, new water and sewer installation, cistern and rural water service, and the excavation and trenching that underground work requires.

How much will my job cost?

Pricing is always upfront and honest with no hidden costs. We tell you what the work involves and what it runs before we start. As our reviews put it: no surprises, just straight up good work at a fair price.

Do you work with builders and contractors?

Yes. We install and run water and sewer for new construction to grade and to code, and coordinate with builders and GCs so the underground work never holds up the project. Local contractors trust us with exactly this.

Do you handle emergencies on weekends and holidays?

Yes. Open 24 hours means exactly that. One of our customers had us come out on a Sunday to fix a leaking cistern. When it is an emergency, we come.

Can you fix a collapsed or broken sewer line?

Yes. We diagnose the real problem, then repair the section or replace the line and re-grade it for proper flow, including the tie-in to the city main when the problem runs that far.

Do you install water and sewer for new builds?

Yes. New service lines, mains, and hookups installed to grade and to code, bedded and compacted so the line you cannot see is one you never have to think about.

Who will I be dealing with?

The owner, Ty, along with his son and crew. The person who plans and prices your job is the person who does it and stands behind it.

Do you clean up after the work?

Always. We backfill, compact, and restore the site so well that customers say you would not know we were ever there.
