Clearing and reclaiming land in Lambertville
Lambertville is farm and open country, and plenty of land here has sat overgrown and unused for years. Land clearing here means taking those lots back and turning them into something useful again, whether that is reclaiming a field for hay, opening ground for livestock to graze, or clearing a pad for a new building.
We clear, grub, grade, and haul so owners can put land that sat idle back to work. That is a big part of what we do here, but it is far from the only thing. We still handle sewer and water lines, septic, grading, driveways, and emergency digs across town.

What tends to be in the ground in Lambertville
Most of Lambertville went up before 1940, across roughly 2,338 housing units.
Close to 52% of it predates 1940. At that age laterals are usually vitrified clay, which takes roots at every joint, and water services are often galvanized steel that scales shut from the inside until pressure falls off.
Housing-age figures: US Census American Community Survey 2019–2023 5-year estimates, table B25034. Pipe service lives are documented industry figures. What is actually under any one property varies, so we confirm it on site before we quote a replacement.
Nearly all of Lambertville is on public water
About 99.7% of Lambertville’s land area sits inside a public water purveyor’s delivery area, all of it served by Veolia Water NJ Lambertville. Sewer is the other half of that, and here the two do not line up: about 56.8% of Lambertville sits inside a mapped sewer service area against 99.7% for water, a gap of 43 points. In that gap you get houses on town water with their own septic system in the yard, which catches people out when a tank needs work in a town that feels fully built up. All of this is land area rather than houses, and a main running past a property does not mean the property is on it, since plenty kept the well after the main went in.

NJDEP maps actual delivery areas for public community systems, meaning fifteen or more year-round connections; smaller shared and association systems are real but do not appear. Percentages are share of land area, not share of homes, and a state file can lag a change of ownership. The name on your bill beats any map, including this one.
The part that changes the job here
Lambertville's water is Veolia, covering essentially the whole city. Sewer is the Lambertville MUA, which also takes Stockton's flow and flow from across the river in Bucks County.
The MUA closed a $2,049,850 NJ Water Bank loan to rehabilitate the North Union pump station after Tropical Storm Ida damaged it. That station moves gravity sewer flow to the treatment plant, so it matters to every lateral upstream of it.
Lambertville is part sewered, part septic
About 56.8% of Lambertville’s land area falls inside a mapped sewer service area, treated at Lambertville Sewerage Authority. A service area is where sewer is planned and permitted, not a promise that a main runs past your house, so the only way to settle it for one address is to look. Outside it, septic.
Sewer connections, laterals and septic work are all things we do, and which one you need is usually settled in one phone call. Sewer and water line work.
