Sewer & Water Line Repair in Hillsborough, NJ
Hillsborough sits about 45 miles south of our Hamburg yard, roughly 70 minutes out, so we can get a crew and the right machine there without a long wait. For an active leak or a backed up sewer in Hillsborough, that matters. We dig out the line, make or coordinate the repair, backfill properly, and put the yard back.
In a township like Hillsborough a lot of homes run on wells and septic, so the buried lines are water service from the well, the line out to the septic tank, and everything in between. Rocky ground and long runs are normal here, and so are we.
Hillsborough is a mix of town sewer and septic depending on the street, so the first thing we work out is which one you actually have.
Work that touches the public side goes through Sewage from the sewered part of Hillsborough is treated by the Somerset Raritan Valley Sewerage Authority, a regional plant running 23.0 MGD of secondary advanced treatment that has served Branchburg, Bridgewater, Hillsborough, Manville, Raritan, Somerville and Warren since 1958. What matters on a service job is what SRVSA does not do: it states plainly that it does not own the collection system of any township it serves, so the main in front of the house, and the records of it, belong to the municipality rather than the authority., and we deal with them directly so you are not chasing it.
One thing worth knowing before you call: Hillsborough is not on one water system but Public water is close to universal here and it is one company: NJDEP's mapped purveyor service areas put about 99.8% of Hillsborough's land area inside a delivery area, essentially all of it New Jersey American Water's Raritan system.. Which one serves your address decides whose records your service line sits in, so it is the first thing to establish rather than the last.
Who owns the sewer in part of this township changed recently. Hillsborough adopted Ordinance 2024-06 on June 11, 2024, granting municipal consent to New Jersey-American Water to construct, lay, maintain and operate wastewater mains in the portion of the township formerly served by the Borough of Manville, and NJAWC petitioned the BPU to approve it on September 9, 2024 under docket WE24090674, with the public hearing held January 7, 2025. The notice states that no increase in rates results from the petition. If the property sits in that former-Manville pocket, the utility to call about the main is not the same one it was two years ago.
How an emergency dig actually goes
Our method is the same wherever we work, and we set it out in full on the sewer & water lines page: what the base and drainage have to be, how we handle the dig, and how we leave the property. This page is about Hillsborough specifically.
If it is the water side you are here about, everything on it is in one place: what a failing service looks like, what replacement costs per foot, and who owns the pipe running in from the street. Water service replacement in NJ
What Hillsborough is actually connected to
About 99.8% of Hillsborough’s land area sits inside a public water purveyor’s delivery area, all of it NJ American Water - Raritan. That matters before a water service job because it decides who owns which end of the pipe and who has to be called before the street is opened.
On the sewer side, about 34.9% of the town falls inside a mapped sewer service area, treated at Somerset Raritan Valley SA, which is 65 points less than the water figure. In that gap sit properties on town water with their own septic system, which is the combination that surprises people mid-job.
Coverage is share of land area, not share of houses, and a main running past a property does not mean the property is on it. Sources: NJDEP Purveyor Service Areas of New Jersey and NJDEP Sewer Service Areas, both read 2026-09-08.

What matters on a service job is what SRVSA does not do: it states plainly that it does not own the collection system of any township it serves, so the main in front of the house, and the records of it, belong to the municipality rather than the authority..

We are roughly 70 minutes out, in Hamburg, and emergencies jump the line. Call 862-268-2510 any hour and we will tell you exactly when a crew can be there, no answering service in the way.
Do I need a plumber or an excavator for a broken line in Hillsborough?
For the buried part of the line, the dig is most of the job and most of the cost. We do the excavation, the pipe work outside the house, the backfill, and the restoration. When a licensed plumber is needed for the connection, we coordinate it. One call instead of two bills.
What is Orangeburg pipe and does my Hillsborough house have it?
Orangeburg is a tar and wood fiber sewer pipe used widely from about 1945 to 1972. It deforms, blisters, and eventually collapses. If your home is from that era and the sewer has never been replaced, a camera inspection is worth it before the line fails on its own schedule instead of yours.
