Septic installation and repair in Merrimack, NH

At C.J. Burke Enterprises we install new septic systems in Merrimack, replace failed ones, and repair the ones that can be saved. We work in Merrimack on properties that are not connected to town sewer. Merrimack is a larger, more built-up town than most of our service area, but a sizable share of it still depends on private septic systems.

Sewer covers part of town — not all of it

Merrimack has a municipal sewer system, and it is easy to assume a Merrimack address is on it. In practice, public sewer serves roughly a third of the town. Coverage is concentrated in much of the area east of the F.E. Everett Turnpike, in parts of central and northeastern Merrimack, and in a southwest area served through Nashua. Many developed neighborhoods outside those areas, including a lot of the western side of town, remain on private on-lot septic systems.

That split is the first thing to get straight. If your house is already close to a sewer line, the town may have connection rules that affect what you can do when a septic system fails; that is a question to take up with the town. If you are outside the sewered area, a failed tank or leach field is a septic replacement job, not a hookup, and it still needs a current NHDES-approved design.

Merrimack lots can also be more constrained than a rural lot in New Boston: tighter yards, neighbors closer in, and less room to stage equipment. We plan around that and use machines that fit the site.

Repairs, replacements, and new work

We install new systems where they are allowed and required, replace failed tanks and fields, and repair problems that do not yet call for a full replacement. NHDES approval still applies. We are installers, not designers, and we work from the approved plan.
