Hingham · Sump Pumps
Water seeping into a Hingham basement, or a pump that drains to the sewer? Call or send a request, and you'll be put in touch with an independent plumber who handles Hingham sump pumps.
Hingham, Massachusetts
Hingham's Sewer Department is blunt about it: connecting a sump pump to the sewer system is strictly prohibited. Groundwater pumped into a sewer takes up room the pipes and pump stations need for wastewater. The department even tells home buyers to have any illicit sump pump connection found and re-routed before the purchase goes through.
So the first question about any pump here is where its water ends up. A discharge hose into a laundry tub, floor drain, or cleanout counts as a sewer connection on a sewered lot. The fix is a line out through the foundation to a spot in the yard that slopes away from the house.
The second question is whether the pump can keep up. Because natural barriers have largely kept storm surge out of Hingham, many wet basements here trace back to groundwater and heavy rain, though low ground near the shore still floods. To talk through either, call or send a request and you'll be connected with an independent plumber who installs and repairs sump pumps in Hingham.
A pump that empties into a sink, floor drain, or pipe in the basement likely violates Hingham's sewer rule and should be rerouted.
Moisture along the base of a fieldstone or block wall after storms suggests groundwater is pressing in from outside.
A pump that never stops may be undersized or have a failed check valve; one that never starts may have a stuck float.
The 2021 Master Plan warns that a major storm could knock out both of HMLP's transmission lines at once. A plug-in pump alone can't help during a long outage.
Local knowledge
One town rule and a set of flood maps frame most sump pump decisions here.
Sewer Hookup Ban
The Sewer Department strictly prohibits sump pump connections to the sewer and urges buyers to have illicit ones located and re-routed before closing. If you're buying a house in a sewer district, ask the home inspector or a plumber to trace where the pump drains.

Flood Insurance Maps
Hingham's first FEMA flood maps date to 1986. Revised Cape Cod Watershed maps were reissued in July 2021 and adopted at that year's Town Meeting, and preliminary Charles Watershed maps re-released in February 2023 cover most of the town. Check the town's flood map page for your street before deciding how much backup protection you need.

Natural Storm Barriers
The 2021 Master Plan says Hingham sits in an inlet shielded from storm surge by Nantasket Beach in Hull and Peddocks Island, which has largely protected it from flooding. It also flags parts of Route 3A, including the rotary, as flood-prone now, so homes in low spots near the harbor shouldn't assume they're immune.
Right now
Handle the electrical risk before the water.
If water in the basement is anywhere near outlets, extension cords, the panel, or appliances, stay upstairs and call 911 or HMLP from a safe spot.
If it's safe, see whether the pump is running and the discharge pipe outside is clear of ice, leaves, or snow.
If you use a portable or utility pump, run its hose well away from the foundation and never into a sink, toilet, or floor drain.
Move boxes, rugs, and anything else you can safely reach to higher shelves while you wait for a plumber.
What to expect
For a new installation, the plumber picks a spot where water collects, cuts and digs a pit through the slab, sets a liner, and runs a discharge line through the wall with a check valve so water doesn't fall back. For a reroute, the main job is replacing an indoor connection with a pipe that exits the foundation.
In an older house with a fieldstone or block foundation, groundwater can find its way in at many points, so a plumber may place the pit where water shows up first. Ask whether a new outlet is needed; electrical work in Hingham needs a utility authorization number from HMLP and goes through the Inspector of Wires, separate from plumbing.
Many plumbers will also suggest a battery backup or a high-water alarm, mounted above the floor. Ask how long a backup can run your pump and how to test it each season.
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.
Confirm the plumber's Massachusetts license with the state's online lookup before work starts.
Have the plumber show where the water will exit and land, and confirm nothing connects to the sewer.
If a new outlet is needed, find out whether the plumber coordinates an electrician and the HMLP authorization.
If you're adding a battery backup or alarm, have the estimate name the equipment and where it will be mounted.
Costs
A replacement pump in an existing pit is the simplest job. Costs rise with digging a new pit through an old slab, running discharge pipe a long way to an outside wall, adding a backup system, or bringing in an electrician for a dedicated outlet.
Get written estimates that list the pump, the discharge route, the backup, and any electrical work. If you're rerouting a sewer connection before a sale, ask the plumber for a short written description of the change for your records.

No. A laundry sink drains to the sewer or septic, and Hingham's Sewer Department strictly prohibits sump pump connections to the sewer. A plumber can reroute the pump to discharge outside.
Yes. The Sewer Department advises buyers to have any illicit sump pump connection found and re-routed before purchase. Ask your inspector or a plumber to trace where the pump discharges.
The town's FEMA flood map page explains which maps apply. Hingham's maps date back to 1986, with revised Cape Cod Watershed maps adopted in 2021 and preliminary Charles Watershed maps covering most of town.
It's worth considering if your basement takes on water in storms, since storms can also cut power. Ask a plumber how long a backup would run your pump and how to keep it charged.
