I spent close to 30 years as a Real Estate agent and house problems are something I was very used to but now that I am retired I discovered just how important a vendor such as Great Falls Septic is. We had problems with our system and of course, the alarm went off. They sent someone to inspect the problem and gave us a list of things that needed to be done. Sure they came out and did the work but even more than that they did it in an efficient and timely Manner and explained every aspect. I do know something about competition for any type of work but in the end, excellence stands out and that is what they are.

I have been using Great Falls Septic for over 40 years. I just had a service on my pump and Leo came out and took care of it in record time. He is SO knowledgeable, professional and friendly. I really am so grateful for his expertise and he always (has been here before!) diagnoses the problem immediately and knows how to fix it. I wouldn’t use any other company!!

We called Great Falls after our sewer backed up into the basement. The person who took the call was very professional and helpful. She dispatched a truck very quickly and it arrived within an hour after the call. The technician, Tony Wine, was extremely courteous, professional, and helpful. He went over and above in his attention to getting the septic tank pumped properly and explaining every facet of the procedure. We have had the tank pumped on several other occasions but this was, by far, the best job ever. Tony was super and also a great guy.

I will recommend Great Falls to anyone needing septic services and will never call anyone else. Kudos to them for a fantastic job.

We recently purchased our first home with a septic system and had no clue what that would entail. Fortunately, Great Falls Septic pumped and inspected the system before we closed on the purchase and then responded within an hour two months later (this afternoon) when water was starting to come out of the cap! We did not know what to do or where to turn, but Leo identified the issue as a tripped circuit and showed me how to reset the alarm and pumps (and even how to open the pump lock with a penny!). Both Leo and the Manager who assisted me on the phone were patient, attentive, answered my many questions, and gave me a terrific education. We are happy to know that Great Falls Septic is there to assist us with our septic needs. We will use them to replace the distribution boxes next week and for all future maintenance. Thanks, Leo and Great Falls Septic!


Courteous, professional and very experienced!  Josh and Leo worked very well as a team to properly diagnose my septic problems and subsequently correct them quickly and effectively.  I had to change two pumps, the floats and also replaced the cement lid.  They also checked the check valves and told me that it wasn’t necessary to change them at this time.  So, based on the overall responsiveness and professionalism of this crew, I would highly recommend Great Falls Septic for this type of work.


I just got a team of 2 guys come and service my septic tank that started to back up this afternoon. Within 30 minutes of calling the company they were here, extremely courteous and polite. Very professional team, I spoke to Zach and he explained the issue.

Not disappointed with them at all. I would highly recommend the company.  We are up and running like normal again.  Thanks Great Falls Septic.  We will be using you again


I have called them twice for what I thought were septic problems – and both times they talked me through several steps of troubleshooting, once helping me fix the issue without them coming out, and the second time helping me identify the problem without them coming. Neither time was I given a bill. This for me is a high level of professionalism and customer service – which I really appreciate. They easily could have sent someone out and charged me for it each time.


“Excellent company! Very handsome young men that are very hard workers completed my job today with ease! I truly couldn’t have asked for better. Thank you Great Falls Septic Service! Call you in another 3 years!”


“I called Great Falls Septic Service to come to check my tank, I was backing up, had a strong sewage smell in the basement. With 2 young children, I didn’t know what to do, but I called Great Falls Septic, talked to the technician and in an hour they came to my rescue. Thank you so much Great Falls for your prompt response, I will recommend you to all my neighbors and friends.”
