If the water is really deep, you might have to use an electric- or gas-powered sump pump. If you use a gas pump, keep fumes out of your house by putting it outdoors and running the hose through a window or door. While it’s important to get the water out of your house as soon as possible, you don’t want to pump it out too quickly if you’re dealing with lots of water in your basement caused by groundwater or floodwater seepage. These floods often cause little or no structural damage because the water pressure inside the basement usually equals that of the water in the ground outside. This stabilizes the walls and prevents cave-ins. Maintaining this equilibrium is necessary to prevent damage. If you pump all of the water out of the basement while the ground is still saturated, the outside water pressure could push in the walls or cause the floors to buckle and heave. Pumping the water out gradually will keep pressure at an even keel inside and out and minimize damage risks. Here’s how to do it: As water levels go down, you might start seeing a certain amount of sludge, sewage, or other debris. It’s all a health hazard, and you want to avoid touching it as much as possible. However, you don’t want to vacuum it up as doing so can clog your vac. Instead, scoop or shovel as much of it as you can into a bucket. For help with repairs to your home after the initial bailing of water, see Cleaning Up After a Flood.
