Clearing and reclaiming land in Lafayette
Lafayette 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, Lafayette 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.

A look at recent excavation, utility, and site work from around Sussex County and northern New Jersey.
What tends to be in the ground in Lafayette
The biggest single stretch of building in Lafayette came before 1940, though the township's 916 housing units are spread fairly wide across the decades.
About 22% predates 1940, so there is a real pocket of clay and galvanized service in Lafayette sitting alongside much newer stock.
A smaller share, around 23%, 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 Lafayette is on a private well
About 1.4% of Lafayette’s land area sits inside a public water purveyor’s delivery area, all of it served by Sparta Twp WU- Lake Mohawk. 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.

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
Lafayette is one of three townships in the whole county, with Sandyston and Walpack, that the county's wastewater plan lists as having no public water supply system. Practically that means a private well, and it changes the job: there is no curb valve for anyone to shut and no utility that owns any part of the line. From the well to the house it is all yours, and all ours to fix. On the sewer side Lafayette sits in the county authority's district.
none, Lafayette is one of only three Sussex County municipalities with no public community water supply system at all
Sewer in Lafayette is a pocket, not a network
About 2.3% of Lafayette’s land area falls inside a mapped sewer service area. The largest share goes to Schering Corp, with 3 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.
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.

Most polygons in this layer are small on-site treatment works for a single school, campground or business, so read the percentages rather than the count.
Lafayette straddles 3 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 Lafayette 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.
- 4.9 acres per system in the Papakating Creek watershed
- 4.8 acres per system in the Paulins Kill, above Stillwater Village watershed
- 4.8 acres per system in the Wallkill River, above the road to Martins watershed, and Lafayette’s zoning here already runs ahead of it, 117 units against 90 allowed
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.
