A perimeter drain and sump pump for Madison basements that take on water at the floor joint, especially in lower areas near the brooks.
In Madison the homes that most often need interior drainage are the ones on the lower edges of town, where groundwater climbs after a long rain and pushes in at the joint between the wall and the floor. The contractor saws a channel around the inside of the basement, sets perforated pipe in stone, and slopes it to a sump pit. Many of the postwar houses built on block foundations in the 1950s and 1960s have no working footing drain, so this system takes over a job the original builders skipped. A wall membrane is often added to carry seepage down into the drain.
The discharge is where Madison needs extra thought. The borough has asked residents not to send sump water into the sanitary sewer, because that water is treated at a cost the town pays and it has overloaded the North Street pump station during storms. Local officials have also warned about pumping onto a neighbor's property. On narrow lots that leaves limited options, so ask the contractor to show you exactly where the line will end, whether it can reach the street or a dry well, and how the outlet will be protected from freezing in January and February.
For an existing pump, a contractor can test the float and check valve, clean silt out of the pit, and replace a unit that runs nonstop after every storm. Older Madison basements sometimes have a pit that was dug years ago with no liner and a pump that is too small for the water it now sees. Battery backup pumps and high water alarms are common additions here, especially in finished basements where a single failed pump could ruin carpet and drywall. Ask the pump's capacity and how long the backup battery should run.
Options usually include a line to the curb, a dry well, or a spot in the yard far enough from both your foundation and your neighbor's property. The borough has discouraged discharge into the sanitary sewer. Ask your contractor and confirm with the building department.
The perimeter strip has to be opened, so drywall and flooring near the walls usually come out and are replaced. Ask for the quote to list exactly what gets removed and who restores it.
Not necessarily. Many ridge homes in Madison leak from roof runoff and poor grading rather than groundwater. Fixing gutters, downspouts, and the slope of the yard may be enough, and a good contractor will say so.
Spring Garden Brook and Black Brook, both Passaic River tributaries, have flooded historically, usually from heavy local thunderstorms and summer and fall hurricanes.

morriscountynj.govThe plan notes inlets on Madison's steep streets work poorly, so runoff overshoots them and collects in flatter areas, and the North Street sewer pump station was overwhelmed by stormwater backup.
