Which Washington? There are four of them
New Jersey has four municipalities called Washington inside our service area. They are separate governments with their own ordinances and their own permit desks, which is what matters before anybody digs. This page is Washington Township, Morris County, 27 miles southwest of our Hamburg yard. If that is not the one you meant:
- Washington Township in Bergen County, the township

Around Washington Township, we deal with a lot of ledge rock
Washington 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, Washington 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 Washington Township
Washington Township has no one dominant building era. Its 2,619 housing units are spread across the decades, with the 1970s the largest single share at 18%.
About 14% predates 1940, so there is a real pocket of clay and galvanized service in Washington Township sitting alongside much newer stock.
Roughly 34% 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.
Washington Township is split between public water and private wells
About 22.7% of Washington Township’s land area sits inside a public water purveyor’s delivery area, shared between 5 different systems. The largest is Washington Twp MUA - Hager, then Washington Twp MUA - Schooleys Mountain. 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.

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
Water and sewer here are run by one township agency, the Washington Township Municipal Utilities Authority (WTMUA) at 46 E. Mill Rd in Long Valley. Its water system is 33 miles of distribution line, 5 elevated tanks holding 1.85 million gallons, and 14 operating wells with a max deliverable capacity of 2.554 million gallons a day; average day is 0.74 MGD. The sewer side is two separate systems: Schooley's Mountain (5 pumping stations, 24 miles of interceptors, a treatment plant built in 1967 rated 500,000 gallons a day, discharging to the South Branch of the Raritan) and Long Valley (2 pumping stations, 12 miles of interceptors).
The MUA is replacing main on the Schooley's Mountain side. It closed a $1.8 million NJ Water Bank loan to replace roughly 2,000 linear feet of aging water main in the Schooley's Mountain section of the system, near Fawnridge Drive. That is a short run of pipe for the money, which is normal for main replacement in developed streets, and it is the same section of the system the MUA inherited from the old Schooley's water company.
The township's sewer mains are actively being rebuilt: the WTMUA's Sewer System Repair and Rehabilitation Program, a $2,193,019.50 project financed through the New Jersey Water Bank (the DEP/NJ Infrastructure Bank low-interest loan program), is rehabilitating sanitary sewer main piping and manholes across the collection system that dates back to the 1967 Schooley's Mountain plant era. Separately the MUA has a $5.45M NJ Water Bank-financed PFAS ion-exchange treatment project for wells SM10-SM17.
The MUA runs two separate public water systems, a legacy of the two private water companies (Schooley's and Hager) it absorbed: Schooley's Mountain (PWSID NJ1438004) and Hager (PWSID NJ1438003). Per the newest annual water quality report, all customer water currently comes from 12 wells, and part of the Schooley's Mountain system gets polyphosphate treatment to sequester iron and manganese; the report also discloses the system exceeded the secondary limit for manganese.
Lead service lines are almost a non-issue in this system. The MUA's September 8, 2025 lead service line inventory lists (by our tally of the address table) 2,715 service lines, and only 2 are lead, both on the customer side in Long Valley (2 Ryan Court and 10 East Maple Ave), plus 10 galvanized lines; every utility-side line is copper or plastic. Note the CCR also discloses the MUA missed the state's July 11, 2025 deadline to file this inventory and its replacement plan, drawing Notices of Violation for both systems.
Sewer in Washington Township is a pocket, not a network
About 8.2% of Washington Township’s land area falls inside a mapped sewer service area. The largest share goes to Schooley s Mountain WTP, with 2 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.

If you find water surfacing in Washington 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 Washington Township that is Washington Township MUA (Long Valley), on 908-876-3145.
The MUA office for the Long Valley and Schooley's Mountain systems. It publishes no 24-hour emergency line anywhere on its site, which is worth knowing before you need one. Much of the township is wells regardless, so check the bill first.
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 Washington Township MUA (Long Valley)'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.
