The size of the dredge, pump system and material agitation method are all project specific andmany times require custom configurations.Dewatering of the slurry can be handled in a variety of ways. Hydraulic dredgescome in all shapes and sizes from largeocean going dredge ships all the way down to small pontoon mounted, hand dredgessuch as the one described in this article.When it comes to hydraulic dredging thereis no “one size fits all” dredge. The mixture of organicand inorganic materials along with wateris referred to as “slurry” and is pumpedthrough the pipeline to a strategically located area for dewatering. Sometimeshydraulic dredging is also referred to as“suction dredging”. Just as the name implies, hydraulicdredging is the use of water to transport theaccumulated material through a temporarypipeline, using a pumping system to basically “vacuum up the muck”. But dredging doesn’talways require draining the pond or lakeand destroying aquatic environments.There are basically two types of dredgingwhen it comes to removing silt, sedimentand other organic and inorganic accumulation from ponds, lakes, streams and otherwaterways mechanical and hydraulic.
