C.J. Burke Enterprises installs new septic systems in New Boston and the surrounding towns. Carson Burke is a New Hampshire licensed septic installer (NHDES permit #5889). If you are building a house, replacing a structure, or adding a system where one is required, we can install the tank, piping, and leach field once the plans are approved.
Call or text 603-303-1543 to talk through the job.

What a new system involves
A septic system is a tank and a leach field (and the pipe that connects the house, the tank, and the field), built to a plan that fits your soil, your lot, and the size of the building. In New Hampshire, that plan has to be prepared by a permitted septic designer and approved by the New Hampshire Department of Environmental Services before construction.
We are installers, not designers. If you already have an approved plan, we will review it, look at the site, and give you a clear picture of the install. If you do not have a designer yet, we can help you understand what you will need and the order of the steps, so you are not guessing your way through it.
On the installation itself, the work typically includes:
- Layout on site from the approved plan
- Excavation for the tank and leach field
- Setting the tank at the correct elevation
- Installing the pipe runs and connections from the building to the tank and from the tank to the field
- Building the leach field as designed
- Backfill, grading, and leaving the site ready for inspection and final cover
The exact system type comes from the design — conventional bed or trench, chamber system, or another approved method — not from a one-size-fits-all package. We install what the approved plan calls for.
Lots that are tight or hard to reach
A lot of new work in this area is not on a wide, open field. We have installed systems on tight lots, on sites with limited room to stage materials, and in places where a large truck cannot get all the way in. Matching the equipment to the site — including smaller excavators, loaders, and dump trucks when that is what the lot allows — is part of getting the system in without unnecessary damage to the rest of the property.
If access, trees, wetlands, or a steep driveway are already a concern, mention that when you call. It is better to plan around those things at the start.
Permits and inspections
A new system generally needs:
- A design from a permitted NH septic designer
- NHDES approval for construction
- Installation by a permitted installer
- Inspection and NHDES approval for operation before the system is put into use
We work with the designer and NHDES on the construction side. We do not skip steps or “figure it out later.” If something on site does not match the plan, that has to be resolved the right way before the job is finished.

Towns we install in
We are based in New Boston, which has no municipal sewer, and we install systems in Milford, Amherst, Wilton, Brookline, Mason, Hollis, Merrimack, Bedford, Mont Vernon, Goffstown, Weare, Francestown, Dunbarton, and Lyndeborough. In towns that have sewer in the village or in part of town, we work on the properties that are on septic — often the more rural roads and outlying lots.
