Dredging: All You Need To Know

If you are in charge of maintaining a waterway, you will need to have it dredged from time to time. Dredging is necessary to keep the water clean and flowing properly. The following is some information on dredging:

What Does Dredging Do?

Dredging is the act of excavating matter from the bottom surface of a body of water. The matter can include weeds, sediment, silt, and any other material that can accumulate at the bottom of the water source. Dredging is generally done when the sediment shifts so much that a boat cannot safely pass through the water. Dredging can also be done in lakes, private ponds, or rivers to remove trash or any other debris that prevents the growth of the habitat.

You need a dredger to effectively dredge a body of water. A suction dredger is similar to a vacuum and is designed to take in the debris. You can also opt for a mechanical dredger, which grabs the material instead of sucking it up.

What Are Different Types of Dredging?

There are two primary ways to dredge a body of water. Hydraulic dredging requires the use of a dredging machine that sucks the sediment from the bottom of the waterway. The sediment moves through a pipeline to a dumping area. The primary disadvantage of hydraulic dredging is that there is a limit to the type and size of the material you can remove. Hydraulic dredging is a great option if you have fine or small material to remove.

Mechanical dredging is an easier way to clean the bottom of the waterway. The equipment is placed on a barge that floats along the water. The machine will dig the sediment from the bottom and scoop it into a bucket. The sediment will stay on the barge until it is taken to the dumpsite.

No matter which type of dredging you choose, you must have an authorized dumpsite to place the debris from the water. The dumpsite must be an enclosed space authorized by the U.S. Army Corps of Engineers. You also must be certain your dredging will not hurt the environment in any way. This includes not placing toxins into the water or in a dumpsite.

Which Type of Dredging Is Best?

The dredging type that works the best for you will depend on your project, the presence of any large obstacles like boulders, and your final budget. Be sure to work with an excavation services company for your dredging needs.
