Septic Pumping and Services You Can Depend On

We are Massachusetts’ Largest Family-Owned Septic System Service and Waste Disposal Company.

Septic services have been Bay State Sewage’s specialty for over 30 years. We know how important safety, reliability, and dependability are to our Southeastern Massachusetts customers. Let us make your septic pumping and services headache-free and affordable.

We work to exceed your expectations with professional technicians that are on time, have the best safety and reliability in the industry, and provide outstanding customer service.

Septic care is NOT an area of the home or business where you should bargain shop. If back-ups occur, it can flood the home or business, leaving everlasting problems within the home or business, such as mold.

It is important to hire a company with experience, long-term employees, and standards of quality that set us apart from the rest. We offer 24/7 emergency service. We will bring you quality septic services at a fair price, so go with the best!

We promise to listen to your needs and will only recommend services that you truly need to fix an existing issue or prevent one from occurring in the future.

No matter how big or small your septic needs are, our staff has the knowledge to guide you through the process and keep your septic system in top condition.



We offer a complete line of commercial and residential treatments and chemicals for septic and grease systems, leach fields, and drains, including BIO-REM, E-D, CCLS, Polylock filters and DRAINMASTER products.

Septic tank treatments and chemicals can prolong the life of your septic system. We’ll even deliver them to your home!


Bay State Customer Review

”I had a problem with my septic system and was not sure what the problem was. Bay State sent out a technician who immediately explained what the issue was and provided me with a free estimate. They walked me through what was causing my system problems and completed the repairs the same day!”
