Hingham · Sewer Lines
Recurring backups, roots, or a broken sewer pipe under a Hingham yard? Call or send a request to be connected with an independent local plumber who serves Hingham.
Hingham, Massachusetts
Hingham's public sewer is smaller than many people assume. The town's Sewer Commission looks after about 30 miles of sewer pipe and 13 pump stations, serving two districts in northern Hingham. The rest of the town, according to the 2021 Master Plan, relies on individual septic systems.
If your home is in one of the districts, the pipe that carries wastewater from your foundation toward the street, called the building sewer or lateral, is where most homeowner sewer repairs happen. Roots, settled sections, and cracked clay or cast iron joints are the usual culprits in neighborhoods that have been sewered since the 1950s.
If you're on septic, a broken pipe between the house and the tank is still a plumbing repair, but the tank and leach field fall under the Board of Health. Either way, you can call or send a request to reach an independent plumber who handles sewer work in Hingham.
A main line that clogs again within weeks of being cleared often has roots or a broken joint holding debris.
When the toilet flushes or the washer empties and the floor drain fills, the line beyond it isn't carrying water away.
Ground that dips or grass that grows faster along the path of the pipe can mark a leak in the line below.
A persistent smell near the cleanout or in the yard suggests a crack letting gases escape.
Local knowledge
Knowing which district you're in tells you where your wastewater goes and who to ask.
North Sewer District
The North Sewer District serves about 2,500 residences and businesses, and its flow goes to the MWRA's Stoddard's Neck pump station in Weymouth. Laterals from that first era of sewering can be decades old, so camera footage is the honest starting point for any repair quote.

Weir River District
The Weir River Sewer District serves the West Corner section, and its flow, combined with that of about 300 Cohasset houses, goes to Hull's wastewater treatment plant. The 2021 Master Plan said this district had no additional capacity at the time, which matters if you're planning an addition that adds fixtures.

Septic Elsewhere
For homes outside the districts, the Board of Health enforces Title 5 (310 CMR 15.000) plus Hingham's supplementary septic rules, revised effective April 1, 2020. A plumber can fix the house-to-tank pipe, but tank or field work involves the Board of Health's process.

Right now
Raw sewage is a health hazard, so protect people before property.
Close off the area, keep children and pets out, and avoid skin contact. If sewage reaches outlets, cords, or the electrical panel, leave the house and call 911.
No flushing, showers, laundry, or dishwasher until the line is cleared. Everything that goes down comes back up at the bottom of the house.
If houses on your street are backing up too, the problem may be in the town main or a pump station. Contact the Sewer Department before hiring anyone.
Take photos for your insurer before cleanup, and wear gloves and boots if you handle anything that touched the water.
What to expect
Expect a camera inspection first. The plumber runs a camera through a cleanout to find the problem and measure roughly how far it is from the house, then explains whether cleaning, a spot repair, lining, or replacement fits the damage.
Digging in Hingham can mean working around mature trees, driveways, and long front yards on larger lots. Repairs and replacements are inspected through the Building Department's Plumbing Inspector, and work that reaches the town's connection may also involve the Sewer Department, so ask the plumber who they'll coordinate with.
On septic properties, the plumber can confirm whether the pipe or the system is failing. If it's the tank or leach field, the repair moves into Title 5 and Board of Health territory, usually with a septic designer or installer.
Hire smart
Plumbing and gas fitting in Massachusetts require a license from the Board of State Examiners of Plumbers and Gas Fitters, and most plumbing work needs a permit from the town's plumbing inspector.
Sewer lateral repair is plumbing work. Look up the plumber's license number in the state's online lookup before you sign anything.
Ask to see the footage or get a copy, with the problem's distance from the house noted, so a second plumber can quote the same repair.
Find out who pulls the permit, books the inspection, and contacts the Sewer Department if the work touches the town's side.
If both digging and trenchless lining are options, ask for each in writing with what's included for restoring the yard or driveway.
Costs
Length and depth of the line, what's on top of it, and the repair method drive most of the cost. A long lateral under a mature lawn or a paved driveway costs more to reach than a short run under open grass, and trenchless lining depends on the pipe being in good enough shape to line.
Get written estimates that list the method, the footage, permits, and restoration. When estimates differ widely, compare the camera findings each plumber relied on, since a different diagnosis usually explains a different price.

Public sewer in Hingham is split between the North Sewer District and the Weir River Sewer District, which serves West Corner. Homes outside both use septic. The Sewer Department can confirm your address.
Ask the Sewer Department before you plan it. The 2021 Master Plan reported that the Weir River Sewer District had no additional capacity, and current rules for added flow are worth confirming in writing.
Sometimes. Lining works when the old pipe is intact enough to hold a liner and isn't badly collapsed or sagging. A camera inspection is the only way to know, so ask the plumber to show you what they see.
It can be either the pipe to the tank or the septic system itself. A plumber can check the line, and if the tank or leach field is the issue, the Board of Health's Title 5 rules apply.
