"RI Septic Design installed my new septic system in my back yard. Mike explained everything clearly from start to finish. I chose this company because they were honest from day one. They took good care to put my yard back in order. They actually removed a few boulders that I had to mow around for years. I would recommend this company completely. If you want the job done right , call Rhode Island Septic Design, Thanks again guys!__Laura D."

"Purchased a new property in the Summer of 2023 and took over a septic installation project from the previous owner. Despite lots of road blocks through the real estate process/state regulators, Mike and Cathy were awesome to work with. They were transparent about their cost and timelines and super efficient. They were a delight to work with, this was a very stressful process for me and they were able to keep me at ease treating their customers with kindness and respect. I wish I could give them 100 stars, they truly went above and beyond and I would not have been able to successfully purchase my first home without their flexibility and expertise in the field. Mike and Cathy, thank you SO much! We will never forget you both and our great experience with your company :)"

"Mike, Peter and John designed and intalled my septic system and were protective of my driveway and pool. They did a great job and were very professional. I highly recommend this family run company."

"Mike was great with explaining all the details of the job and why the tank had to be replaced, when replacing the leach field. They were on time and communicated every detail. They also did not price in the loom that they used to grade the property after because they forgot to and did not try to throw it in after the job was complete. A plus company and did a great job!!!"
