Clearing and reclaiming land in Washington Township
Washington Township 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.
Helpful guides: Storm damage: document before you clean up · Preventing erosion after excavation
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, Washington Township 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 Washington Township
Washington Township has no one dominant building era. Its 2,619 housing units are spread across the decades, with the 1970s the largest single share at 18%.
About 14% predates 1940, so there is a real pocket of clay and galvanized service in Washington Township sitting alongside much newer stock.
Roughly 34% dates to the 1940s through early 1970s. That is the Orangeburg window, and pipe from it is past the age where it can be counted on.
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 Washington Township is on public water
About 99.7% of Washington Township’s land area sits inside a public water purveyor’s delivery area, all of it served by NJ American Water - Washington/Oxford. That is land area rather than houses, so the properties on a well tend to be the outlying ones on bigger lots. Public water running past a house does not always mean the house is on it either, since plenty of properties 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.
Sewer in Washington Township is a pocket, not a network
About 7% of Washington Township’s land area falls inside a mapped sewer service area. The largest share goes to Hawk Pointe, with 5 smaller works alongside it. 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.
