Drainage and grading in Pohatcong
Pohatcong 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.

Warren County is farm country and river valley, with long rural driveways, big lots, and a lot of grading and drainage work. Properties out here usually need real earthmoving, not just a quick patch.
As a township, Pohatcong 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 Warren 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 Warren County and northern New Jersey.
What tends to be in the ground in Pohatcong
The biggest single stretch of building in Pohatcong came before 1940, though the township's 1,470 housing units are spread fairly wide across the decades.
About 23% predates 1940, so there is a real pocket of clay and galvanized service in Pohatcong sitting alongside much newer stock.
The bigger issue here is the 54% 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 Pohatcong is on a private well
About 8.7% of Pohatcong’s land area sits inside a public water purveyor’s delivery area, shared between 3 different systems. The largest is Aqua NJ - Phillipsburg, then Aqua NJ - Warren Glen. 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.

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
Pohatcong has no treatment plant of its own. The township runs the local sewer system and pumps everything to the Phillipsburg Sewage Treatment Plant under contract, alongside Alpha, Greenwich, Lopatcong and Phillipsburg itself. Pohatcong holds 0.540 MGD of that plant's 3.5 MGD permitted capacity, and actual township flows ran about 0.201 to 0.328 MGD over 2009-2015.
Two water purveyors reach into Pohatcong: Alpha Municipal Water Works and Aqua NJ Water Company-Phillipsburg (the old Consumers NJ Water Company). Their mains only cover the built-up north end around Alpha and the Route 22 corridor; the rest of the township is on private wells.
Aqua's state-required service line inventory for its Phillipsburg system (PWSID NJ2119001, certified July 2023) lists 11,061 service lines; plotting the inventory's coordinates against the official municipal boundary, 798 of them sit inside Pohatcong Township: 712 confirmed not lead, 32 galvanized, 1 lead, and 53 whose material nobody has verified yet. Under New Jersey's 2021 lead service line law, the galvanized and lead lines must be replaced and the unknowns identified.
Septic and well work in Pohatcong goes through the Warren County Health Department, not town hall. The county reviews plans for new septic systems and wells, physically inspects the installations, and will not let a new well go into service until the water passes testing for metals and organic compounds.
Sewer in Pohatcong is a pocket, not a network
About 7% of Pohatcong’s land area falls inside a mapped sewer service area, treated at Phillipsburg 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.

If you find water surfacing in Pohatcong, 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 Pohatcong that is Aqua New Jersey, on 877-987-2782.
Aqua serves the developed pockets; most of the township's ground is wells and septic. The 24/7 number is the same either way, but check the name on your bill before assuming Aqua is yours.
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 Aqua New Jersey'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.
