Clearing and reclaiming land in Stillwater
Stillwater 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, Stillwater 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 Stillwater
The biggest single stretch of building in Stillwater came before 1940, though the township's 1,858 housing units are spread fairly wide across the decades.
About 25% predates 1940, so there is a real pocket of clay and galvanized service in Stillwater sitting alongside much newer stock.
The bigger issue here is the 46% built between 1940 and the early 1970s. Orangeburg pipe was rated fifty years and routinely goes oval and collapses closer to thirty, so in a township weighted this heavily toward that window it is less a question of if than which street.
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 Stillwater is on a private well
About 1.8% of Stillwater’s land area sits inside a public water purveyor’s delivery area, all of it served by Stillwater Water District 1. 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.

Source: NJDEP Purveyor Service Areas of New Jersey, edition 2025-07-03, measured against US Census municipal boundaries. 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
Water District #1 of Stillwater Township
Public water in Stillwater is not a township department and not a private company. It is a water district, Water District #1, running on its own wells, and it covers a slice of the township rather than all of it. Outside that district you are on a private well, which changes the job completely: there is no curb valve to shut, and the line running to the house is entirely yours.
Stillwater is septic country
NJDEP maps no sewer service area anywhere in Stillwater, 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.

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.
Stillwater 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 Stillwater 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.
- 4.8 acres per system in the Paulins Kill, above Stillwater Village watershed
- 4.8 acres per system in the Trout Brook / Swartswood Lake watershed
- 4.7 acres per system in the Paulins Kill, below Stillwater Village 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.

If you find water surfacing in Stillwater, call this first
Before you call us, get the water shut off. A leaking service line washes ground out from under whatever sits above it and keeps running until somebody turns the curb valve.
In Stillwater that is Water District #1 of Stillwater Township, on 973-579-1579.
Public water here is a water district running its own wells, not a township department, and it covers only part of Stillwater. Outside the district you are on a private well, and there is no curb valve for anyone to shut.
Once the water is off, the repair is ours. What replacing a water service involves, or what the first hour of a break looks like.
Read off Water District #1 of Stillwater Township's own published page and re-checked periodically. If your bill carries a different name, that name is the one with your curb key. Much of New Jersey is served by New Jersey American Water, 1-800-272-1325, 24 hours.
