Clearing and reclaiming land in Walpack
Walpack is farm and open country in a county that leads New Jersey in hay and livestock, and a lot of land here has sat overgrown 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.

Sussex County is lake country and rolling farmland, and plenty of homes out here run on well and septic with older service lines. This is our own backyard, so we know the rocky ground, the frost depth, and the lake-community setups better than most.
As a township, Walpack 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 Sussex County. We show up when we say we will, and we leave your property graded and clean.

Water lines in Walpack are nearly all private
NJDEP maps no public community water system anywhere inside Walpack, so the usual arrangement here is a private well and the whole run from the wellhead to the house belongs to the owner. That is not the only arrangement, though. Shared wells serving a handful of houses, and small association systems, sit below the threshold the state maps and do not appear on it at all. If you get a water bill from somebody, you are on one of those, and there may well be a shutoff and a shared length of pipe involved.
What replacing a water line involves is the same trench whichever of those you are on, and well lines and shared lines are both work we do regularly. Which towns around here have public water, and the arrangements the state map cannot see, are on who supplies water in your NJ town.

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
Walpack is the strangest municipality we cover and worth being straight about. It is the oldest township in Sussex, incorporated in 1731, and it had 7 residents at the 2020 Census. Most of it sits inside the Delaware Water Gap National Recreation Area after the federal government bought out the community in the 1960s for the Tocks Island Dam, which was never built. There is no public water system. If you own one of the few remaining private properties here, everything is well and septic and access is the whole job.
none, Walpack is one of only three Sussex County municipalities with no public community water supply system
Walpack is septic country
NJDEP maps no sewer service area anywhere in Walpack, 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.

Walpack straddles 4 watersheds, and the septic density is different in each
First, what this is not: it is not a minimum lot size, and it does not mean a house here needs acres of land to get a septic. Plenty of working systems in Walpack sit on far less. It is the figure the state uses to judge how many more systems the ground can absorb before groundwater nitrate becomes a problem, and it matters most if you are subdividing.
- 5 acres per system in the Flat Brook watershed
- 4.8 acres per system in the Little Flat Brook watershed
- 4.6 acres per system in the Van Campens Brook / Dunnfield Creek watershed
- 4.5 acres per system in the Walpack Bend / Montague Riverfront watershed
Watersheds do not follow town lines, which is why two neighbors on one road can fall either side of a number. The whole county, watershed by watershed.
