On the other hand, this unit will provide you with the means to renew the quality of your waterfront, and the quantity of removed sediment will be limited only by the amount of time & energy that you put in to it. Even expensive industrial dredges can’t do that. The mud is not going to come out of your discharge hose looking like toothpaste.
You are also going to have to be prepared to deal with the fact that you will be pumping a lot of water along with the sediment. If you are cleaning a modest area, such as around a dock or boat slip, you can expect to get the job done relatively quickly. My problem, however, is that I am not getting the suction I need. Ive seen lots of videos on you tube about how to make them and I have a pretty good one built. These volumes may vary depending upon the nature of your sediment, distance pumped, and your energy & skill level, but many operators state that they are able to pump a much larger volume than our estimates. I have been toying with a homemade hand dredge, simalr to ones you can buy at the gold shows for about 100. The excavation capability of our dredger is about 60 cubic meter of water per hour, along 6 cubic meter of sediment per hour. Our suction dredger is particularly effective in removing sand, silt, and that fluffy black stinky mud that ruins the waterfront and prevents one from enjoying beach and water activities.
