We do a lot of Brightspeed fiber construction around Frenchtown
A significant part of our work in Frenchtown 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.
In a built-up borough like Frenchtown, 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 Hunterdon 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 Frenchtown
Most of Frenchtown went up before 1940, across roughly 696 housing units.
Close to 53% 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 30% 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 Frenchtown is on public water
About 96.9% of Frenchtown’s land area sits inside a public water purveyor’s delivery area, all of it served by NJ American Water - Frenchtown. Sewer is the other half of that, and here the two do not line up: about 49.7% of Frenchtown sits inside a mapped sewer service area against 96.9% for water, a gap of 47 points. In that gap you get houses on town water with their own septic system in the yard, which catches people out when a tank needs work in a town that feels fully built up. 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
Frenchtown's water is now NJ American Water, drawn from the Brunswick aquifer, on a system that state source water records still list under the old Frenchtown Water Department name. Sewer is still the borough's own treatment plant, with about half the borough's land mapped inside its service area.
Frenchtown is part sewered, part septic
About 49.7% of Frenchtown’s land area falls inside a mapped sewer service area, treated at Frenchtown Boro STP. 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.
