Clearing and reclaiming land in Allamuchy
Allamuchy 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.

Warren County is farm country and river valley, with long rural driveways, big lots, and a lot of grading and drainage work. Properties out here usually need real earthmoving, not just a quick patch.
As a township, Allamuchy has the kind of larger properties where septic systems, grading, drainage, land clearing, and long driveways come up most. Whether it is an emergency sewer or water line dig-out, a septic system, a lot that will not drain, or a new driveway, we bring our own equipment and an operator who knows the ground in this part of Warren County. We show up when we say we will, and we leave your property graded and clean.

A look at recent excavation, utility, and site work from around Warren County and northern New Jersey.
What tends to be in the ground in Allamuchy
The biggest single stretch of building in Allamuchy came in the 1970s, though the township's 2,501 housing units are spread fairly wide across the decades.
A smaller share, around 25%, falls in the 1940s-to-early-70s Orangeburg era, so it turns up on some streets and not others.
With 29% built since 2000, a good part of Allamuchy is newer, and there the work is usually drainage and grading rather than pipe.
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.
Most of Allamuchy is on a private well
About 7.9% of Allamuchy’s land area sits inside a public water purveyor’s delivery area, shared between 2 different systems. The largest is Allamuchy Twp Water and Sewer, then Hackettstown MUA. Outside those pockets most properties are on a well, sometimes their own and sometimes one shared with neighbors, and the three situations are different jobs with different rules. Which one you are in is the first thing to settle, and your bill settles it faster than any map.

The part that changes the job here
the Allamuchy Township Department of Water and Sewer Utilities
Allamuchy's utility started life as a private company. The township's own page dates it to 1969 and names it as formerly the Pequest Water and Sewer Co., now run as a township department serving just over 4,000 residential and commercial customers, largely the Panther Valley side. The wastewater plant runs 0.2 to 0.3 million gallons a day against a 0.6 capacity, so there is real headroom there, which is not true everywhere in Warren County.
Sewer in Allamuchy is a pocket, not a network
About 14.6% of Allamuchy’s land area falls inside a mapped sewer service area, treated at Pequest Sewer Company. 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.
