Water in New London
Where New London gets its water — and why it matters.
The New London Department of Public Utilities supplies the city and neighbouring Waterford — around 45,000 people in total — from surface water: lakes and reservoirs in a protected watershed across Waterford, Montville and Salem, with Lake Konomoc storing over a billion gallons.
The utility disinfects with sodium hypochlorite and reports an average chlorine residual in the New London distribution system of around 1.72 ppm, with sodium around 9.6 ppm and disinfection byproducts within regulatory limits.
New London’s other distinguishing feature is its housing. This is one of the older housing stocks in the region, and the pipe between the water main and your kitchen tap belongs to the building, not the utility. No water quality report can describe what happens in that last stretch.

What homeowners notice
Common water concerns in New London.
These are symptoms, not diagnoses. What is actually causing them at your address is a question for a test — but knowing what to look for is where it starts.
Drinking water in an older building
A utility's report covers the water it delivers to the street. Point-of-use reverse osmosis treats the water where you actually drink it, after your own plumbing.
Seasonal taste and odour
Reservoir supplies shift through the year. Carbon filtration evens it out.
Rental and multi-family buildings
Under-sink systems work in apartments and condos where a whole-home install is not on the table.
Two different starting points
City water and well water are different problems.
Municipal / City Water
If you’re on public water in New London
New London is a public water city, so everything here happens at the point of use. The water arrives treated, monitored and reported on. What you can change is what happens after it enters your building: carbon filtration for chlorine taste, and an under-sink reverse osmosis system for drinking and cooking. In an older building, or a rental where you cannot touch the main line, the under-sink system is often the entire sensible answer — and we will say so rather than quoting you a whole-home system you cannot install.
Every recommendation we make is based on the water conditions in that specific home. We don’t quote equipment before we understand what the water is doing.
Harborline solutions
What we install in New London homes.
Four core systems and a set of add-ons. Which one fits depends on your water source and what a test actually finds.
Whole-Home Softener + Filtration
High-capacity softening paired with coconut shell carbon, installed where water enters the house.
Private Well Systems
Dual-tank treatment with air injection for iron, sulfur and manganese, configured to your well.
Iron & Sulfur Removal
Peroxide injection at the point of entry for wells where staining and rotten-egg odour dominate.
Reverse Osmosis Drinking Water
A tankless seven-stage under-sink system on its own faucet, for drinking and cooking.
Carbon & Specialty Filtration
Carbon-only, salt-free conditioning, UV and pre-system sediment filtration where they’re the right call.
Free installation & warranty
Standard installation in the package price, lifetime coverage on qualifying dry parts.
We don’t claim any system removes a specific contaminant from your water. What a given system addresses depends on its actual specifications and on what your water actually contains.

Questions
New London water questions, answered.
Where does New London's drinking water come from?
Surface water. The New London Department of Public Utilities draws from lakes and reservoirs in a protected watershed across Waterford, Montville and Salem, with Lake Konomoc as the primary reservoir. The system serves New London and Waterford.
Why does New London water taste like chlorine?
The utility disinfects with sodium hypochlorite and reports an average chlorine residual around 1.72 ppm in the New London distribution system. That is within regulatory limits, and it is also enough for most people to taste in a glass or in coffee. Carbon filtration removes it.
Do I need a water softener in New London?
Almost certainly not. This is treated surface water, which in this region is generally low in hardness. If scale is genuinely a problem in your building, we will measure before recommending anything.
I rent my apartment. Can I still filter my water?
Yes. An under-sink reverse osmosis system fits a single kitchen and does not require touching the building's main line. It is the usual answer for apartments, condos and rentals.
I live in an old building. Should I filter my drinking water?
The utility's testing describes the water delivered to the street, not what happens in a building's own pipes. If that gap concerns you, treating the water at the point you drink it is the direct response.
