For those inquiring about the term "dewatering"; The construction definition pretty much matches Websters. It means to remove water.
What that can entail when it comes to construction is damming off an area like a canal, lake or a portion of either and removing the water for construction work. More commonly it is a system used to lower groundwater levels to prevent flooding of an excavation site. Lastly, it can also be a combination of the two.
In Florida, dewatering is pretty much par for the course for any decent size excavation.
