Pipe bursting in Boston
When a sewer line is too far gone to line, pipe bursting replaces it along the same path through two small pits, with the yard, the front walk and the street in between left alone.

What pipe bursting does
Pipe bursting replaces a sewer line without digging it up. A cone-shaped bursting head, slightly larger than the old pipe, is pulled through it by a cable or rod from a pit at one end to a pit at the other. As it moves it splits the old clay, cast iron, Orangeburg or PVC outward into the surrounding soil, and new high-density polyethylene pipe, fused into one continuous length, follows directly behind it along the same path. The lawn, the front walk, the driveway, the basement slab and the street between the two pits are never opened. In Boston, where a lateral runs from the basement under the yard and the sidewalk to a main in the road, that is the difference between a day and a week with a police detail.
When it is the right method
Cured-in-place lining is the first choice for most Suffolk County laterals, because it works through the cleanout with no pits at all. But a liner needs a host pipe that still has its shape. The camera sometimes finds a section that has collapsed, a run of postwar Orangeburg that has flattened, a belly so deep it holds standing water, or a pipe that was too small for the house, which is common where a single-family home became a two- or three-family. Those lines cannot be lined, and bursting replaces them. The head can be sized to upsize from 4 to 6 inches in the same pull. the verified installer for Boston explains the choice on a Boston job from the footage.
How the job runs
The camera inspection maps the line and locates the collapse or belly. The crew opens a launch pit near the main and a receiving pit at the house, a few feet square each; where a cleanout riser or a manhole already exists, that is used instead. The bursting head and the fused HDPE pipe are staged, the pull begins, and the old pipe fractures outward as the new one is drawn in. The new pipe is connected at both ends, the pits are backfilled and compacted, and the camera records the finished line. A residential pull is usually done in a day, and it is done in winter: the pits are small enough to open through frost, and the pull itself happens below it.
What you get
A brand-new pipe. Fused HDPE has no joints for roots to enter, does not corrode, and is rated for a hundred-year service life. It bends with frost heave and soil movement rather than cracking, which matters in the clay and glacial till under Suffolk County. Where a liner restores the old pipe, bursting removes the old pipe from the equation entirely, which is why it is the method for lines beyond restoring. The methods are compared at the CIPP and trenchless reference.
Permits and the street
Bursting under the public way needs a street-opening permit in addition to the plumbing permit, and many Massachusetts communities require the sewer department to witness the connection at the main before the pit is closed. The contractor pulls the permits and schedules the inspections. Dig Safe utility locating is part of every bursting job, since the head moves soil and must stay clear of water, gas and electric lines; that is on the contractor, not the owner.
What to ask
Ask why bursting rather than lining, and expect the answer to point at the camera footage. Ask what pipe is going in, how it is joined, and the warranty term. Ask about permits, locating and restoration of the two pits. Verified installers for this work are listed at the installer directory.

Questions we hear about pipe bursting
When is bursting better than lining?+
When the pipe no longer has a shape to line: a collapse, a crushed section, flattened Orangeburg, a long belly, or a line that needs to go up a diameter. Lining is the first choice when it is possible; bursting is the answer when it is not. The camera decides.
How big are the pits?+
A few feet square at each end of the run, one at the house side and one near the connection to the main, often at an existing cleanout or inside a manhole. Everything between them stays undisturbed.
What pipe goes in?+
High-density polyethylene, fused into one continuous length with no joints, rated for a hundred-year service life. It flexes with frost heave instead of cracking, which matters in New England ground.
Can the line be made bigger at the same time?+
Yes. Upsizing a 4-inch lateral to 6 inches is a common reason to choose bursting, especially for a house that was converted to apartments or has added bathrooms since the line was built.
