There are a number of tools you can use to get floodwater out of your house, including:
A sump pump: A sump pump pumps groundwater away from the foundation and basement.
A wet/ dry vacuum: A wet/dry vac sucks up water and is useful for getting water out of carpets in particular.
Plastic buckets: Buckets are another means of removing water. Usually, though, these aren’t as effective as vacs.
A squeegee: A Squeegee is used on hard surfaces to push water out of structures.
Dryers and fans: Dryers and fans get the air circulating, which remove remaining moisture in your home.
Dehumidifiers: Dehumidifiers are important tools for getting rid of any excess moisture.
