Family owned and operated since 1972, St. Onge provides reliable septic tank pumping for both residential and commercial properties throughout New Hampshire. During a routine pumping we inspect your septic tank for any issues involving excess buildup, missing baffles, or clogged filters. Your satisfaction is our priority and we pride ourselves in the relationships we build with our customers. We take the time to be professional, clean, and informative. We are licensed in the state of New Hampshire for septic design and installation.

We are proud of our American flag, being family owned and operated, and most of all our Dad, Mom, and brother Raymond that are no longer with us but helped get this company to where it is today.
