Northborough, MA at a glance
One supply source
Every Northborough home draws from the same MWRA connection, so problems that appear in only one house are almost always inside that house.
Emergency dispatch
Emergency dispatch is available around the clock for Northborough, with licensed plumbers sent from Westborough.
Main roads
Route 20, Route 9 and Route 135 are the three approaches we use, and the Route 20 and Route 9 junction is the shared landmark.
Neighbors
Southborough, Shrewsbury, Marlborough, Berlin and Boylston touch the town line, so a call near the edge may be handled from the closest page.
The water bill jumped and nothing is dripping
In 2021 the town delivered 326 million gallons to 4,233 accounts, according to the MWRA's Northborough community page. Divide one number by the other and the average account used about 77,000 gallons that year, or roughly 210 gallons a day. That average includes businesses, so a quiet household should sit below it, but it gives you a rough yardstick.
If your own use climbs well past your normal pattern, suspect a hidden leak before you suspect the meter. A toilet flapper that seeps into the bowl can waste hundreds of gallons a day without a sound. A cracked line behind a wall or under a slab can waste far more.
A leak detection visit starts at the meter. We confirm the dial moves with every fixture off, then use acoustic listening gear and a thermal camera to mark the spot before anyone cuts into drywall.
A fifteen minute check before you call about a bill
These steps take no tools and tell dispatch a great deal when you call.
- Turn off every tap and appliance, read the meter, then read it again 15 minutes later. A moving dial means water is leaving the house.
- Add a few drops of food coloring to each toilet tank and wait without flushing. Color in the bowl points to a worn flapper.
- Look at the base of the water heater and the discharge pipe from its relief valve for moisture.
- Check washing machine hoses and the shutoff valves under each sink for crust, drips or bulging rubber.
- Listen near the main shutoff for a faint hiss while everything is off.
- If the meter keeps moving after all of that, close the main valve and call the 24/7 line.
Drains that back up on the lowest floor first
Water follows gravity, so a blocked main line shows itself at the lowest drain in the house. A basement floor drain that gurgles when the washing machine empties, or a shower that rises when someone flushes upstairs, usually points past the individual fixture.
One slow sink is normally a trap or branch problem and responds to drain cleaning with a cable. When two or more fixtures complain at once, the stoppage is probably in the 4-inch main, and a camera run along with sewer line cleaning tells us whether roots, grease or a collapsed section is the cause.
Stop running water while you wait. Every gallon you send down a blocked main has to go somewhere, and it often ends up on the basement floor.
What the MWRA connection means for the pipes inside your house
The table separates what the published numbers say about the town from what they mean for a single house.
| Fact | Covers | In your house |
|---|---|---|
| 100 percent of water came through one metered MWRA connection in 2021 | The supply for the whole town | Questions about what comes down the main go to the town and the MWRA reports. A plumber cannot change what arrives at the street. |
| Lead tap tests at 15 homes: 90th percentile 1.56 ppb against a 15 ppb action level | A small sample of homes, not yours | A result under the action level does not describe your tap. A certified lab tests a specific tap, and a plumber can identify supply pipe and solder type. |
| Copper 90th percentile 130 ppb against a 1,300 ppb action level | The same sample | Copper supply lines are normal here. Pinhole leaks in aging copper are a wear issue and belong in a leak check. |
| About 65 miles of distribution pipe and over 575 hydrants | The town's side of the system | Pressure swings on your street can come from main work. Ask the town before assuming your own plumbing failed. |
No hot water on a weekday morning
A tank heater that has stopped heating usually has one of four faults: a tripped breaker or dead igniter, a failed thermostat, a burned element, or a tank that has rusted through. The first three are repairs. A tank that leaks from the shell is finished.
Most tank heaters serve for roughly 8 to 12 years, so a unit at that age with a wet floor beneath it is a replacement call. We explain both routes on the water heater repair page, and the replacement page covers sizing, venting and expansion tanks.
Turn the gas valve or the breaker off before you mop. Standing water around a powered heater is a shock hazard.
Where we work in Northborough
Dispatch covers all of ZIP 01532. The easiest reference point when you give an address is the junction of Route 20 and Route 9 by the New England Baseball Complex, because every driver in town knows it. Route 135 gives a second approach from the Westborough side.
Calls in the 01532 ZIP most often involve drain cleaning, leak detection and water heater repair, which is why those pages sit first in the menu. Northborough borders Southborough to the southeast and Shrewsbury to the west, and our Southborough and Shrewsbury pages cover those neighbors. Marlborough, Berlin and Boylston are also nearby.
Before we arrive in Northborough
Four moves limit the damage while a plumber is on the way.
Close the main valve
Find it where the line enters near the meter. Read the meter once more after closing it. If the dial still moves, the leak is ahead of your valve and the town should know.
Cut power near the water
Turn off breakers for any room with standing water or a wet ceiling. Do not touch outlets with wet hands.
Clear the area
Move rugs, boxes and electronics out of the wet zone and open cabinet doors under the affected sink.
Call the 24/7 line
Describe what you see, which floor it is on and whether the water is stopped. Photos for insurance can wait until the flow is controlled.

What shapes the price of a Northborough visit
A clear price is quoted before any work starts, and these are the things that move it.
Homeowners policies usually cover sudden water damage but not a slow leak that went unnoticed. Photograph the damage and read your policy before you decide.
For the real number on your job, call and describe what you see.
Northborough has one water source and a clear set of regular troubles, so most visits come down to finding which fixture or line in the house is behind the symptom. Call when you have shut the main and read the meter, and we will take it from there.
Code and standards note. Plumbing in Northborough follows the same state code, 248 CMR 10.00, while permits come from the town's building department. According to the MWRA, the town's water is monitored for lead and copper, and those results describe the supply and not your tap.
Northborough plumbing questions
Yes. The 24/7 line is answered at night, on weekends and on holidays, and licensed plumbers are dispatched from Westborough, about 12 minutes away by our estimate. Tell dispatch whether water is running now so the first steps can start by phone.
Yes. Dispatch covers every address in ZIP code 01532, from the Route 20 and Route 9 junction by the New England Baseball Complex to the side streets along Route 135 and the roads toward the Marlborough and Berlin lines. The most common visits there are drain cleaning, leak detection and water heater repair.
The MWRA supplies the water, so there is no local well to treat. Fixtures, heaters and pipe choices follow your house and budget. If you want a specific tap tested, a certified lab does that testing and we do not make health claims.
A main break or a pressure loss across several homes belongs to the town. Check your own shutoff first, and if it is closed and water still flows in the street, call the town. If the leak sits between the meter and the house, call us.
A plumber can examine the pipe where it enters the house and identify its material. Whether lead is in the water at your tap is a lab question, so use a certified lab for that.
Give the street, the nearest cross street and whether the home is on Route 20, Route 9 or Route 135 or a side road off them. Mention which floor the problem is on and if the main valve is within reach.
