Fiber optic construction is active in Sussex right now
Right now, a large share of what we do in Sussex is underground utility work for fiber optic internet. Planet Networks has been building high speed fiber across Sussex County for years and is closing in on covering nearly every home in the county, and our background in underground utility construction is a big reason providers lean on crews like ours to get these lines in the ground, town by town.
We handle the boring, trenching, conduit, and restoration so the network goes in clean and yards get put back the way we found them. 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.
In a built-up borough like Sussex, the common jobs are sewer and water lines, underground utilities, and excavation in tighter spots. 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.

What tends to be in the ground in Sussex
Most of Sussex went up before 1940, across roughly 1,023 housing units.
Close to 42% of it predates 1940. At that age laterals are usually vitrified clay, which takes roots at every joint, and water services are often galvanized steel that scales shut from the inside until pressure falls off.
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 Sussex is on public water
About 94% of Sussex’s land area sits inside a public water purveyor’s delivery area, all of it served by Sussex WD. Sewer coverage tracks it closely, about 84.6% of the town, so most properties here are either on both or on neither. 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
the Sussex Borough Department of Public Works
Sussex Borough splits it the way Stanhope does, and it catches people the same way. Public Works, out on Brookside Avenue, runs the physical water and sewer system. Tax and Utility Collections on Main Street handles the bill. Water coming up out of the ground is a Public Works call. The borough's sewage goes to the county authority's Upper Wallkill plant rather than being treated in town.
Most of Sussex is inside a sewer service area
About 84.6% of Sussex’s land area falls inside a mapped sewer service area, treated at Sussex County MUA Upper Wallkill WPCF. 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.
Sussex sits in one watershed, at 4.9 acres per septic system
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 Sussex 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, and Sussex’s zoning here already runs ahead of it, 2 units against 1 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.
Sussex County Wastewater Management Plan, December 2017, Table 9. Zoning changes and DEP updates its model, so this is the last published position rather than a ruling on any property. Your town’s zoning office and the county Health Department are the ones that decide.
If you find water surfacing in Sussex, 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 Sussex that is Sussex Borough Department of Public Works, on 973-875-4202.
Public Works at 33 Brookside Avenue runs the physical system. The Tax and Utility Collections office at 973-875-4831 handles the bill. For water in the ground, call the first one.
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 Sussex Borough Department of Public Works'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.

Sussex is roughly 10 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 Sussex?
Yes. Sewer and water line repair and replacement is core work for us in built-up parts of Sussex County like Sussex, 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 Sussex County and six other counties. We pull the permits, mark out, and do it by the book.
