Clearing and reclaiming land in Glen Gardner
Glen Gardner 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 Glen Gardner
Most of Glen Gardner went up in the 1980s, across roughly 748 housing units.
About 22% predates 1940, so there is a real pocket of clay and galvanized service in Glen Gardner sitting alongside much newer stock.
A smaller share, around 20%, falls in the 1940s-to-early-70s Orangeburg era, so it turns up on some streets and not others.
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 Glen Gardner is on public water, but not all of it
About 55.4% of Glen Gardner’s land area sits inside a public water purveyor’s delivery area, shared between 2 different systems. The largest is Glen Gardner WD, then Hampton Borough WD. Sewer is the other half of that, and here the two do not line up: about 0.4% of Glen Gardner sits inside a mapped sewer service area against 55.4% for water, a gap of 55 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
Glen Gardner has a small borough water department, but public sewer is essentially absent, and the borough's proposed wastewater plan, submitted to NJDEP in February 2024, proposes no future expansion of the sewer service area.
The same proposed plan removes 50.5 acres from the sewer service area, the land tied to the Eastern Concrete Materials quarry, and its build-out analysis found room for zero additional septic systems in the Highlands Preservation Area.
Glen Gardner is septic country
NJDEP maps no sewer service area anywhere in Glen Gardner, so the working assumption on any property here is a septic system, and the disposal field and the ground it sits in are the job rather than a connection. That is a planning map rather than a survey, so it is not proof that no small local collection system exists anywhere in the township. What it does mean is that there is no planned municipal sewer to tap.
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.

Glen Gardner is roughly 55 minutes from our Hamburg base, so we can usually be out for an estimate quickly, and for a sewer or water line emergency we start moving right away, day or night.
Do you handle sewer and water line work in Glen Gardner?
Yes. Sewer and water line repair and replacement is core work for us in built-up parts of Hunterdon County like Glen Gardner, including tight-access digs and emergency line breaks. Many homes here built between 1945 and 1972 still have Orangeburg sewer laterals, a wood pulp and tar pipe that fails with age, and replacing those laterals is routine work for us.

Yes. JWSR LLC is a licensed and insured New Jersey contractor, and we work across Hunterdon County and six other counties. We pull the permits, mark out, and do it by the book.
