We do a lot of Brightspeed fiber construction around Union
A significant part of our work in Union is underground construction for Brightspeed's fiber internet network. Brightspeed has been rolling fiber out fast across Hunterdon and Somerset County, already reaching tens of thousands of homes and businesses, and putting that network in the ground is exactly the underground utility work we specialize in.
We take care of the trenching, conduit, directional boring, and cleanup so the build moves and the properties get restored right. 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.

Hunterdon County is rural and agricultural, heavy on well and septic systems, stone, and long private drives. It is exactly the kind of ground our equipment is built for.
As a township, Union 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 Hunterdon 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 Hunterdon County and northern New Jersey.
What tends to be in the ground in Union
The biggest single stretch of building in Union came in the 1950s, though the township's 21,932 housing units are spread fairly wide across the decades.
About 21% predates 1940, so there is a real pocket of clay and galvanized service in Union sitting alongside much newer stock.
The bigger issue here is the 56% 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 Union is on a private well
About 7.6% of Union’s land area sits inside a public water purveyor’s delivery area, shared between 2 different systems. The largest is Clinton WD, then Edna Mahan Correctional. 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.
Sewer in Union is a pocket, not a network
About 10.1% of Union’s land area falls inside a mapped sewer service area. The largest share goes to Town of Clinton STP, with 9 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.
Worth knowing separately: a proposed facility, Brinkerhoff Tract proposed, would cover about 1.5% of Union if it is built. Proposed is not built, and we have kept it out of the figure above for that reason, but if you are planning around a future connection here it is the thing to ask the town about.
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.
