Wat moet ik in huis hebben voor wateroverlast?

Een dompelpomp met afvoerslang en koppelingen, het liefst als complete calamiteitenset, en een plek waar je het water veilig kunt lozen.

Wat zit er in een calamiteitenset?

Een dompelpomp, een afvoerslang, snelkoppelingen en meestal een draagkorf of box voor transport, opslag en als grof filter.

Waar laat ik het water heen bij wateroverlast?

Naar een straatkolk, put of hemelwaterafvoer die niet terugloopt in het pand. Leg de slang niet vlak langs de gevel.

Mag ik zelf water wegpompen als er stroom in het spel is?

Schakel eerst de stroom uit in ruimtes waar water bij stopcontacten of apparaten komt. Twijfel je, laat dan een installateur kijken.

Flooding after heavy rain: emergency plan and disaster kit

September 13, 2026

Quick answer: every minute counts when it comes to flooding. Prepare an emergency kit with a pump, hose, and couplings, so you don't have to search or order when the water is already inside. Know the lowest points in your building, know where the water can drain, and test the pump once a year.

Before the rain: prepare yourself

Prepare an emergency kit in a fixed, dry, and accessible place, not in the basement itself.
Know where the water can drain: a pit, a street drain, or a rainwater drain that doesn't flow back. Make sure the hose is long enough.
Check gutters, drains, and light shafts for leaves and debris, especially in autumn.
Place valuables higher up in the basement, cellar, or garage.
Test the pump annually: run it in a bucket of water for a short time.

During flooding: checklist

Safety: switch off the power in areas where water comes into contact with sockets or appliances.
Place the pump: put the pump in its carrying basket at the lowest point.
Connect the hose: connect the hose and lay it to a drainage point that does not flow back.
Power: use a socket outside the wet area and keep the plug dry.
Pumping: let the pump run. With a float, it switches itself off; without a float, stay with it.
Document: take photos and videos for your insurer.

After the flood

Remove the last few centimeters with a flat suction pump, ventilate well, and let wet floors and walls dry to prevent mold. After use, rinse the pump with clean water, let it dry, and put the complete kit back. If the water came from the sewer, clean the area extra thoroughly and consider installing a backflow preventer.

What's in an emergency kit?

Component	Why
Submersible pump	The heart of the kit; can often handle lightly polluted water too
Drain hose (e.g., 12.5 m)	Flat hose, compact to store
Quick couplings	Connected within a minute, without tools
Carrying basket or box	Transport, storage, and coarse filter so the pump doesn't get clogged

Which kit to choose?

For homes and small businesses, a light, compact kit that can handle clean to lightly polluted water is sufficient. For homeowners' associations, commercial buildings, and large basements, choose a kit with more capacity and jacket cooling, so the pump can run for long periods. On construction sites or with mud and sand, you'll want a robust kit with a stirring head.

Does your property flood frequently? Then an emergency kit is not enough. Install an automatic pump with a float permanently in a pump pit. See basement flooded.
