![]() In order to determine the cubic yards, take the acres that are going to be dredged and multiply 1,600 cubic yards per foot of material depth.įor instance, if the depth of the material that is going to be dredged is six feet and you have a ten-acre lake, then the formula will be 10 x 6 x 1,600 = 96,000 cubic yards. It depends on the type of job and what tools are necessary to do it.Īccording to the website, the dredging job is priced, in general, by the cubic yard of the material that will be dredged. Major works like these, for which you need heavy machinery will be priced with thousands of dollars per hour. On the other hand, you should be prepared to spend much more if the work is more complex than just restoring the canal depth, like deepening a harbor or a shipping channel. Expect to spend a few hundred dollars per hour on this type of work. ![]() For instance, you can just use a large bucket and do the job from the bank of the canal, if you only need to deepen a drainage canal. So, the prices are not fixed, and it may be quite difficult to find a contractor that can give you a quote over the phone. However, as the degree of this job varies greatly, the term of dredging is very broad. The cost of dredging is anywhere between $7 and $25 per cubic yard, depending on several factors such as the nature of the material that is dredged, the amount of the material that has to be dredged, and the place where the material can be placed once it is taken out. ![]() However, most of the time, dredging is carried out for waterway maintenance purposes and to ensure the necessary flow of water by reducing/eliminating silting (silting means the filling or raising of the bed of a watercourse, the bottom of a lake or reservoir, by depositing the material transported by the flowing waters – plant remains, sediments, alluvium). The reasons for carrying out the dredging process are multiple. Over time, these deposits can affect maritime traffic or the proper functioning of that waterway. Dredges typically involve a layer of soft material that forms when plants, debris, soil, or leaves settle to the bottom of navigable waters. ![]() The origin of the word “dredging” comes from the old English word “ dragan“, which means to pull, to extract. ![]()
