Which Chester? There are two of them
Morris County alone has two municipalities called Chester. They are separate governments with their own ordinances and their own permit desks, which is what matters before anybody digs. This page is Chester Township, 26 miles south of our Hamburg yard. If that is not the one you meant:

Around Chester Township, we deal with a lot of ledge rock
Chester Township sits in the New Jersey Highlands, where the bedrock is ancient, hard gneiss and granite that often sits close to the surface. Because that rock resists erosion, digging here regularly runs into ledge, and it takes the right equipment to get through it.
We bring in the bigger machines and the tools to break out and remove ledge rock so the job keeps moving, whether it is a foundation, a utility trench, or a septic field. Rocky ground is where experience really shows. 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.
As a township, Chester Township 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 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 Township
The biggest single stretch of building in Chester Township came in the 1980s, though the township's 2,692 housing units are spread fairly wide across the decades.
Roughly 35% 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 Chester Township is on a private well
About 4.7% of Chester Township’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 AMW Four Seasons at Chester. 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.
What replacing a water service involves, and who supplies water in every town we cover.
Source: NJDEP Purveyor Service Areas of New Jersey, edition 2025-07-03, measured against US Census municipal boundaries. 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
There is no township water or sewer department to call. Health services are shared: since July 1, 2022, Randolph Township supplies the licensed health officer (paperwork side) and Roxbury Township handles the environmental field inspections, and even they don't touch septic, the township's page says septic inspection and plan review go to a third-party engineering firm (Boswell).
Something is about to change under these streets. On July 15, 2025 the township adopted Ordinance No. 2025-12 granting New Jersey Natural Gas a franchise to provide natural gas service and to use the township's roads and streets to do it, limited to fifty years, and the Board of Public Utilities approved it on March 4, 2026, effective the 11th, under docket GE25070390. Read it for exactly what it says and nothing more: the Board wrote that approval of the municipal consent does not constitute approval of any specific main extension or plan for service, so this is permission to serve the township, not a schedule for any particular road. What it does mean is that streets with no gas in them today may not stay that way, and a yard that has never needed a gas markout may start getting one.
The whole township sits inside the NJ Highlands Region, and 15,789 of its 18,695 acres, about 84 percent, are in the stricter Preservation Area, where NJDEP Highlands rules add a layer on top of normal permits for land disturbance, new wells, and septic density. The township is fully conforming with the Highlands Regional Master Plan and can issue certain Highlands exemptions itself.
Chester Township has no water utility of its own. The only public water mapped in the township is NJ American Water's Short Hills system, and it reaches only a small piece of the northeast corner, in the subwatershed shared with the Mendhams. The state Highlands plan for that corner says everyone outside those lines pumps their own well, and it pegs that subwatershed's published net water availability at a deficit of about 11,000 gallons per day, so wells there are drawing on stressed groundwater.
Septic work in Chester Township goes through the township Board of Health, but the actual inspections are farmed out to Boswell Engineering (908-879-6209). Since 1/1/24 the fees are: $220 per lot per day to witness soil logs, $990 inspection plus $50 application for a new or expanded system, $880 for an alteration without expansion, and $220 to $550 for repairs depending on whether it's a tank/line/D-box or the disposal field.
Chester Township is septic country
NJDEP maps no sewer service area anywhere in Chester Township, 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.
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 Chester Township, 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 Chester Township that is New Jersey American Water, on 1-800-272-1325.
Only small pockets of the township sit in NJAW's delivery area. Most homes are on their own well and septic, where the shutoff is the pump breaker rather than a curb valve.
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 New Jersey American Water'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.
