Standing water near electrical equipment is dangerous, and every hour of flooding increases damage. Act immediately.
Call (866) 417-0220Why it happens in Indianapolis
Combined sewer surcharge
Intense rain fills combined sewers and pushes water up floor drains in older neighborhoods.
Sump pump failure
Worn pumps, stuck floats and outages fail during storms.
High spring groundwater
Saturated soil pushes water through foundations.
Water heater and supply leaks
Basement heaters and hoses fail and flood quickly.
Downspouts and grading
Downspouts that dump next to the foundation and soil sloping toward the house send storm water straight into basement walls and sump pits.
Signs to watch for
- Water around the sump pit or floor edges
- Water coming up through the floor drain
- Water near the water heater or washer
- Damp walls after rain
- Musty smell and efflorescence on walls
Emergency, or can it wait?
Call right away if…
- Water near outlets, the panel or appliances
- Sewage in the basement
- Water rising during a storm
Usually OK to schedule if…
- Minor dampness after rain with no standing water

Basement Flooding in Indianapolis: questions
How do I protect an Indianapolis basement from sewer backups?
A backwater valve blocks reverse flow from the public sewer. Pair it with a sump pump and battery backup for groundwater.
Is basement floodwater dangerous?
Sewer backflow is contaminated, so avoid contact and keep people and pets away. Discard soaked porous materials.
Will insurance cover my flooded basement?
Sewer backup and groundwater usually need separate coverage. Check your policy before storm season.
Did DigIndy stop basement backups?
The tunnel system reduces combined sewer overflows to waterways, but private laterals and local sewer capacity still matter for basement backups.
Should I finish my Indianapolis basement if it has flooded before?
Fix the source first — backwater valve, sump pump with backup, grading — and use flood-tolerant materials before investing in a finished space.
