Replacing aging driveways and walls in Somerville
Somerville 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.

Somerset County is denser and more suburban, which brings more sewer and water line work, underground utilities, and hardscaping on established properties.
In a built-up borough like Somerville, 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 Somerset 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 Somerville
The biggest single stretch of building in Somerville came before 1940, though the borough's 5,726 housing units are spread fairly wide across the decades.
About 25% predates 1940, so there is a real pocket of clay and galvanized service in Somerville sitting alongside much newer stock.
The bigger issue here is the 51% 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 Somerville is on public water
About 100% of Somerville’s land area sits inside a public water purveyor’s delivery area, all of it served by NJ American Water - Raritan. Sewer coverage tracks it closely, about 92.4% of the town, so most properties here are either on both or on neither. 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
Somerville sold its sewers. NJ American Water completed its acquisition of the borough's wastewater system on October 3, 2023, and it also supplies the water, while the Somerset Raritan Valley Sewerage Authority treats the flow.
SRVSA closed a $33 million NJ Water Bank loan for a facility that treats wastewater from Somerville's sewer overflow point during major storms and discharges it to the Raritan River, which is meant to keep heavy rain from sending untreated overflow out at that connection.
Most of Somerville is inside a sewer service area
About 92.4% of Somerville’s land area falls inside a mapped sewer service area, treated at Somerset Raritan Valley SA. 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.
