Norwich, CT — The Rose of New England
A tour of excavation across Norwich.
Six neighborhoods. Three rivers. One municipal utility under every street. Here’s what each corner of Norwich actually looks like from the excavation side — and how we work it.

- ·Street-opening utility trenches
- ·Mill-village foundation repair
- ·Controlled rock & blast work
Where the Yantic meets the Shetucket and the Thames starts south. Dense 18th-century building stock, narrow streets, and river-edge flood considerations — FEMA maps matter here before you break ground. Typical work: sewer and water taps through NPU, tight-access foundation repair, and carefully staged street-side trenching.
The original agricultural center of Norwich before the harbor took over. Older colonial-era lots, mature trees, the Norwichtown Green Historic District. Work here is usually foundation and drainage, done carefully around close-set old houses and long-established landscape.
Built in 1866 around Ponemah Mill — once the largest textile mill in the world under a single roof. The village is dense with 19th-century worker housing, rubble-stone foundations, and water/sewer laterals that are decades past their original design life. Typical work: foundation replacements, basement expansion for egress, sewer lateral replacement under narrow streets.
William Greene bought the land in 1826 and transferred it to the Norwich Water Power Company; the Shetucket dam and canals were finished by 1833 and powered tens of thousands of spindles. Today it's a tight grid of mill-era homes on sloping lots. Foundation repair, tight-access excavation, and sewer lateral work dominate.
Named after the Yantic River running through it. Originally its own mill town — Yantic Woolen Company — it grew as a planned grid with duplex worker housing and Grace Episcopal Church at its center. Work is usually infrastructure-adjacent: utility trenches, foundation stabilization, and careful work around the planned streetscape.
Norwich's residential terraces rise up from the harbor — Laurel Hill and Bean Hill sit high above Chelsea with real grade. Retaining walls, hillside foundation excavation, and drainage regrading become the dominant job type. This is where Norwich stops being a river town and becomes a hill town.
Before we dig in Norwich
Norwich Public Utilities owns the grid. We call, we wait for marks, we coordinate.
NPU owns water, sewer, electric, and natural gas — four services under one roof. Every job in a Norwich right-of-way needs an NPU-coordinated permit and a notice to the NPU Project Coordinator at least one business day before work.
Call Before You Dig (CBYD) comes first on any dig, public or private. Controlled blasting within 200 ft of NPU facilities triggers a formal procedure: coordinator at (860) 823-4513.
General guidance. Confirm current requirements with NPU (customer service: (860) 887-2555), the City of Norwich, and CBYD (811) for your specific parcel.
If your project touches a Norwich street, it touches NPU. Let’s plan it together.
