Septic Service in
the Black Hills.

I have worked with Hills Septic on multiple occasions, including several properties with unique septic systems and challenging circumstances to work through. They have been an incredible resource every time! Their knowledge of different types of septic systems, their condition, and the areas they serve is extremely impressive. As a real estate professional, deadlines matter, and Hills Septic has gone above and beyond to help get the job done when it mattered most, ensuring necessary septic work was completed so a real estate closing could happen on time. That level of responsiveness and commitment is invaluable when you have buyers, sellers, lenders, and other parties depending on everything coming together. Hills Septic is my go-to septic company, and I know I can lean on them for knowledgeable, dependable assistance. Sarah is always incredibly friendly, responsive, and helpful. I highly recommend Hills Septic to anyone looking for a company that truly knows their business and can be counted on when it matters!

Hills Sanitation is amazing! Consistently professional, exemplary service. I was having a “glitch” with another company and Hills came to my rescue and took care of my porta potty servicing needs during the recent Sturgis Motorcycle Rally. A+++++. I highly recommend, and will absolutely be a customer for life!

A big shout-out to Hills Septic for outstanding service! When we thought we were out of luck during the start of rally week, they came to the rescue faster than we ever expected. Professional, reliable, and went above and beyond. Five stars!

Emilee is amazing to working with!! I'd do business with hills again.

Awesome service! Septic was backing up on a Sunday afternoon. Called and they were at my house within an hour. Couldn't be happier with service!

Great service! Showed up after hours and took excellent care of us. Would definitely recommend to family and friends.

Hills was fantastic to deal with. Super fast and friendly. I highly recommend them.

I love these guys! With multiple septic systems they keep everything straight and always do a great job. If you need prompt, reliable service from knowledge people this is where to turn. You won't be disappointed!

These guys were awesome to deal with. Called them up with less than 24 hours-notice. I worked with Jenna and she said let me make a few changes and we will accommodate you. Top notch.

I've worked with Hills Septic for both my personal properties and on numerous real estate transactions. They're always communicative, knowledgeable, and incredibly helpful. A special shout-out to Jenna, she's always on top of things and a pleasure to work with!
