Drainage and grading in Phillipsburg
Phillipsburg has stretches of low ground and a high water table, so drainage problems and seasonal flooding come up again and again here. That is why a good chunk of what we do here is drainage and grading.
When a yard will not drain, a basement keeps taking water, or a lot floods every spring, that is our wheelhouse: French drains, regrading, swales, and moving water away from the house for good. 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.

What tends to be in the ground in Phillipsburg
Most of Phillipsburg went up before 1940, across roughly 7,018 housing units.
Close to 48% 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 36% 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.
Most of Phillipsburg is on public water, but not all of it
About 81.9% of Phillipsburg’s land area sits inside a public water purveyor’s delivery area, all of it served by Aqua NJ - Phillipsburg. Sewer actually reaches further than water here, about 94% of the town against 81.9%, which is the less common way round. It means properties drawing from a well while discharging to a public sewer, so the two sides of the house answer to different owners. 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
Phillipsburg splits water and sewer between a company and the town, and then ties them back together in a way worth knowing. Water is Aqua New Jersey, a private utility. Sewer is the town's. But the town computes your sewer bill from water consumption, and the meter readings behind it are taken by the water company rather than by the town. So one private company's reading drives a municipal bill, and a water leak on your side of the curb can show up twice.

Most of Phillipsburg is inside a sewer service area
About 94% of Phillipsburg’s land area falls inside a mapped sewer service area. The largest share goes to Phillipsburg STP, with 1 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.
