Place the hose of a wet/dry vac into the deepest portion of the water. A wet/dry vac works like a regular vacuum, except it functions equally well at vacuuming water. It pumps water through the hose into a reservoir. You might need an extension cord to power the vacuum, depending on where the water is located. Keep the power cable dry when using the vacuum.
Turn the wet/dry vac on and hold the hose in place as it pumps water from the driveway or garage to the reservoir.
Monitor the reservoir level on the vacuum. Unplug the vacuum and dump the reservoir out when it is close to full.
Continue this process until all the excess water is gone.
