A former mill village on the Westford side of town
West Chelmsford lies in the northwest of town. It was first called Farwell Village, and later Scythe Factory Village, after a mill that Deacon John Farwell built on Stony Brook to make scythes. A post office followed and the village took the name West Chelmsford.
The mill is long gone, but the village kept its name and its streets. This page covers what we could verify about the area, the two housing patterns the records describe, and the questions that save time when you call about a plumbing problem.
Where West Chelmsford sits
- The village is in the northwest part of Chelmsford, along Stony Brook. The Chelmsford Historical Society notes that one mill straddled the town line, sitting partly in West Chelmsford and partly in Westford.
- In the colonial period Westford Street was the town's west end, and the 1980 state survey records the scythe mill village developing after 1823.
- Listing sites describe the area as a suburban pocket along US Route 3, a commuter route toward Boston and Nashua. Treat that as a description, not a boundary.
- Because it sits close to Westford, some calls cross the line. See our Westford plumber page for the neighboring town.
Two housing patterns the records describe
The 1980 state survey places Greek Revival and Italianate side-hall houses at the southern edge of the village along School Street, with more modest side-hall houses built along School Street before 1890. That is the old village pattern.
The town master plan adds the second pattern. It says single-family homes are most prevalent in West Chelmsford, and that most homes in town are detached single-family houses built in tract subdivisions. The two patterns sit close together, so houses on neighboring streets can be decades apart in age.

Questions that save time on the call
- Your street address. A street name can repeat across the area.
- The age of the house, if you know it, and the year of the water heater.
- Town sewer or a septic system. The town does not publish a street-by-street list, and the Sewer Division at 978-250-5233 can check its plans.
- Which water district serves you. Check the bill, because Chelmsford has three districts.
Basements, pumps and wet weather
A house near a brook is a reason to test the sump pump before a storm, not a sign that yours will fail. Pour a bucket of water into the pit and watch that the float lifts and the pump runs and shuts off. If it does not, see sump pump repair and replacement.
- Do not stand in water to reach a pump, an outlet or the electrical panel.
- If water is rising toward outlets or the panel, stay out of the basement and call 911 if you smell gas or see sparks.
- Unplug the pump before you touch it, and do it from dry ground.
- A pump that hums but does not move water needs a plumber, not a hammer.
Water on a basement floor after rain can come from the pump, the discharge line, a window well or the foundation. Foundation cracks are a job for a foundation specialist, and we say so on the phone. For the plumbing side, our guide to basement water control explains what we handle.
Which service fits the problem
- Slow drain at one fixture: drain cleaning.
- Water heater leaking or out of hot water: water heater repair and replacement.
- A water bill that does not match your use: leak detection.
- A toilet that runs or leaks at the base: toilet repair.
What we could not confirm
We could not confirm a published boundary for West Chelmsford, which streets use which ZIP code, or which streets are sewered. The town does not map these in a form we could verify. We also found no evidence that plumbing in West Chelmsford fails more often than elsewhere, so this page does not suggest it.
Plumbing work in Massachusetts follows the state plumbing code, 248 CMR. Sump pump wiring follows the National Electrical Code (NEC) and should be done by a licensed electrician. The village history comes from the Chelmsford Historical Society's article on West Chelmsford and the Massachusetts Historical Commission's 1980 reconnaissance survey.
Plumbing questions in West Chelmsford
It is the northwest part of Chelmsford, along Stony Brook and close to the Westford line. It began as Farwell Village around a scythe mill.
It depends on the street. The town Sewer Division keeps as-built plans for most sewer connections, and a septic system falls under the Board of Health's maintenance rules adopted February 3, 2026.
Yes. Call and give your street and town, and we will confirm. We also have a page for Westford itself.
Lift the lid, pour in a bucket of water and watch the float rise and the pump start and stop. If it does not, call before the next storm.
