Central Indiana ground is mostly dense clay left behind by glaciers. It soaks up spring rain and holds it, and the water table rises. The City of Carmel, right across the White River, puts it plainly in its engineering FAQ: most local soils drain very poorly, have seasonal high water tables, and it is common for basements to flood when the soil is saturated. Fishers basements face the same ground.
How Fishers basements usually flood
- The sump pump fails. Pumps wear out, floats stick, and check valves fail. A pump that has run for years without attention can quit on the wettest night of the year.
- The power goes out. A strong thunderstorm can cut power just as the pit fills. Without a battery backup, the pump stops.
- The pump can’t keep up. In long, heavy rain, a small pump or a frozen or clogged discharge line can be overwhelmed.
- Window wells fill up with rain or debris and leak through the window.
- Seepage through cracks in the wall or the joint where the wall meets the floor.
- Inside sources: a water heater, water softener, or washer in the basement. See water damage restoration.
- Floor drain or ejector pit backups. That water should be treated as sewage; see sewage backup cleanup.
Safety first
Do not step into standing water if outlets, cords, the furnace, or the electrical panel are wet or close to it. If you cannot reach the breaker without stepping in water, wait for a professional or call your electric utility. Have gas appliances that were under water checked before you use them again.
What the cleanup usually looks like
- Pump out standing water and extract the carpet.
- Remove wet carpet pad, which rarely dries well in place.
- Cut out the bottom of wet drywall (often called a “flood cut”) and pull wet insulation.
- Dry the slab, framing, and remaining materials with dehumidifiers and air movers, checking moisture daily.
- Look at the sump pit, pump, and discharge line, and point you to a plumber or waterproofing company if they need work.
Sump pump tips from Hamilton County
The Hamilton County Soil and Water Conservation District recommends a battery backup and an alarm for sump pumps that sit inside a basement, and check valves to keep water from flowing back during heavy rain. It also says sump pumps should carry only groundwater and storm water to a storm drain, while floor drains and other sewage need a separate ejector pump tied to the sanitary sewer. The county surveyor’s office notes that most newer subdivisions provide a sump outlet for each lot.
- Test the pump every few months by pouring water into the pit.
- Add a battery backup or a water-powered backup pump.
- Install a high-water alarm so you hear about trouble early.
- Keep the discharge line clear and free of ice in winter.

Quick answers
Is a sump pump failure covered by insurance?
Often only if your policy has a water backup or sump overflow endorsement. Standard policies typically exclude it, and outside flooding usually needs separate flood insurance. Check with your agent.
How long does it take to dry a basement?
It depends on how much water there was and what got wet. Providers measure moisture each day and remove equipment once materials are back to normal readings.
