Which Chester? There are two of them

Replacing aging driveways and walls in Chester Borough
Chester Borough is a long-established community, and in older neighborhoods the driveways, retaining walls, and drainage that went in decades ago are wearing out. A big part of what we do here is tearing out cracked, failing work and rebuilding it to last, often on tight lots where access takes real care.
We also do a fair amount of site work where older properties are being rebuilt or expanded. 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.

Morris County runs from busy suburban neighborhoods to wooded hillsides, and the work follows suit, from tight utility repairs to regrading sloped lots that will not drain.
In a built-up borough like Chester Borough, 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 Morris 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 Chester Borough
Chester Borough has no one dominant building era. Its 554 housing units are spread across the decades, with before 1940 the largest single share at 19%.
About 19% predates 1940, so there is a real pocket of clay and galvanized service in Chester Borough sitting alongside much newer stock.
Roughly 38% 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 Chester Borough is on public water
About 99.6% of Chester Borough’s land area sits inside a public water purveyor’s delivery area, shared between 2 different systems. The largest is NJ American Water - Short Hills, then Windy Acres Mobile Home. Sewer is the other half of that, and here the two do not line up: about 0% of Chester Borough sits inside a mapped sewer service area against 99.6% for water, a gap of 100 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
Sewer in Chester Borough is the Borough's own operation, and it is tiny: the Chester Borough WTF at 111 Oakdale Road (NJPDES permit NJ0054101) is permitted at just 0.075 million gallons a day, and it discharges treated sewage to the ground, not to a stream. There is no regional sewer line out of town, even the Chester Springs Shopping Center on Route 206 runs its own separate 0.03 MGD package plant under its own permit (NJ0090115).
New projects here cannot count on borough sewer. The Chester Borough Center development (Mill Ridge Lane / Turkey Farm site on Route 24) had to get NJDEP to approve its own 15.2-acre discharge-to-groundwater sewer service area with a brand-new on-site treatment plant for a projected 26,125 gallons a day, because the whole borough sits in the Highlands planning area (fully conforming, with a Highlands Center designation) and the local subwatershed is already in deficit on net water availability.
New Jersey American Water is the water utility here, and it just spent about $1.8 million in Chester Borough (July-August 2026) swapping roughly half a mile of old 8-inch main for new 12-inch ductile iron on Perry Street, Maple Avenue and Old Gladstone Road, replacing 18 utility-owned service lines and upgrading 5 fire hydrants to improve fire flow. The service-line work is part of the company's push to get every lead and galvanized line out of the ground by 2031.
Sewer capacity in the borough is rationed: every property carries a fixed sewage allocation, and any change of use or building expansion needs a Borough capacity review (a $100 application fee plus $500 escrow) with flow numbers worked up by a licensed NJ Professional Engineer. A residential connection permit is $75, and you must pull a plumbing permit from the Borough for the connection and lateral before you tie in. The Borough's own form warns applicants to settle sewer capacity before spending money at the Planning or Zoning Board.
Chester Borough is septic country
NJDEP maps no sewer service area anywhere in Chester Borough, so the working assumption on any property here is a septic system, and the disposal field and the ground it sits in are the job rather than a connection. That is a planning map rather than a survey, so it is not proof that no small local collection system exists anywhere in the township. What it does mean is that there is no planned municipal sewer to tap.
Worth knowing separately: a proposed facility, Proposed Chester Borough Wastewater Treatment Facility, would cover about 60.4% of Chester Borough 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.
