Clearing and reclaiming land in West Amwell
West Amwell is farm and open country, and plenty of land here has sat overgrown and unused for years. Land clearing here means taking those lots back and turning them into something useful again, whether that is reclaiming a field for hay, opening ground for livestock to graze, or clearing a pad for a new building.
We clear, grub, grade, and haul so owners can put land that sat idle back to work. 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.

What tends to be in the ground in West Amwell
The biggest single stretch of building in West Amwell came in the 2000s, though the township's 1,234 housing units are spread fairly wide across the decades.
About 17% predates 1940, so there is a real pocket of clay and galvanized service in West Amwell sitting alongside much newer stock.
Roughly 37% 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.
With 29% built since 2000, a good part of West Amwell is newer, and there the work is usually drainage and grading rather than pipe.
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 West Amwell is on a private well
About 2% of West Amwell’s land area sits inside a public water purveyor’s delivery area, all of it served by Veolia Water NJ Lambertville. 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.

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
West Amwell has no public water or wastewater utilities of its own. The Music Mountain development next to Lambertville is served by Veolia; the rest of the township is on individual wells, and septic systems.
The township's 2025 housing plan puts the land needed per home to stay within the groundwater nitrate standard at between 6.0 and 6.2 acres, depending on the watershed, which is why new septic lots here are large.
West Amwell is septic country
NJDEP maps no sewer service area anywhere in West Amwell, 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.
