Drainage and grading in Alpha
Alpha 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.
In a built-up borough like Alpha, 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 Warren 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 Alpha
The biggest single stretch of building in Alpha came before 1940, though the borough's 1,022 housing units are spread fairly wide across the decades.
About 29% predates 1940, so there is a real pocket of clay and galvanized service in Alpha sitting alongside much newer stock.
The bigger issue here is the 49% 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 borough 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.
Nearly all of Alpha is on public water
About 93.7% of Alpha’s land area sits inside a public water purveyor’s delivery area, all of it served by Alpha Municipal Water Works. Sewer is the other half of that, and here the two do not line up: about 61.1% of Alpha sits inside a mapped sewer service area against 93.7% for water, a gap of 33 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.

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 Alpha Municipal Water Works, run by the borough itself
Alpha is a small borough that never handed its water to anybody. The Alpha Municipal Water Works covers about 94 percent of the borough's land, which in a corner of Warren County where the private companies took over most systems is worth noticing. The sewer side is the opposite: roughly 61 percent of Alpha drains to Phillipsburg's plant rather than to anything of Alpha's. So the water is local and the wastewater is not, and which one your problem sits on decides who you are dealing with.
Most of Alpha is inside a sewer service area
About 61.1% of Alpha’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 Alpha, 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 Alpha that is Alpha Borough Department of Public Works, on 908-454-3143.
The borough names this line for meter faults, water quality and technical questions, weekdays 7 to 3. Billing is the Utility Collector at 908-454-0088 ext 120, which is not who you want with water running.
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 Alpha 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.

Yes. Sewer and water line repair and replacement is core work for us in built-up parts of Warren County like Alpha, 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.
