You’ve got a major dredging project coming up, and you’re not sure which dredging system to use. After all, there’s a myriad of options out there, and some might serve your needs better than others. Don’t stress over this decision anymore than you need to. We at U.S. Aqua Services have assembled this quick guide to help you figure out which system is going to meet your needs.

Hydraulic dredgers act as a giant, underwater vacuum cleaner to clean and remove sediments. By sucking up a combination of sediment and water, hydraulic dredgers create what is called a “slurry.” This slurry is moved from the surface and then onto the surface via a pipeline or tube.
This is widely considered the most effective method of dredging when the environment and the ecosystem of the dredging site is of major concern. It is preferred because it prevents most of the contaminated sediments from being dispersed or released into the nearby water source. While this is a major advantage to hydraulic dredgers, they do have their limitations. Because of their design, hydraulic dredgers are excellent for moving loose soils, sands. Silt, gravel, or rocks can cause undue wear and tear on the hydraulic system.
Mechanical dredging necessitates the use of heavy equipment to dig up the bottom of a water source, and move it. This equipment can be moved to the job site by a barge, or the body of water can be drained, allowing the equipment to move to the site on its own. Some specialized mechanical dredging equipment can drill or dig up the dirt.
While mechanical dredging is the most commonly rented form of dredging machinery, that does not mean it is always the most effective. Because this form of dredging requires a bucket or digger to impact and shovel away the sediment, there is a higher chance of contaminated materials within the sediment to be dispersed into the water surrounding it. The contaminated soil can fall out of, or through the bucket, and spread further into the water.
Which Is Best?
Both forms of dredgers have their benefits. While hydraulic dredgers are precise, and fast, they aren’t able to take on heavier materials. Mechanical dredgers are cumbersome and imprecise, but they can move fast quantities of heavy materials with minimal effort. One might be better suited to your dredging job than the other, but often using a combination of the two leads to the best outcomes.
Dredgers are ideal for a variety of projects because of their ability to move, and remove materials like trash, gravel, and sediment. Dredging can help keep waterways, like rivers and streams clean and help restore their beaches and land from the effects of erosion. Additionally, they can be used to maintain the stability of harbors, ports and marinas.
At U.S. Aqua Services, we offer both hydraulic and mechanical dredge rentals. Our unique, in-house hydraulic dredger is suited for tough jobs that most other hydraulic dredges can’t handle. Used for offshore and inland dredging, our system works faster and more efficiently than others by combining mechanical cutters with a series of hydraulic pumps. This means we can dredge 300-600 cubic yards of material per hour, all with precise spoil control, meaning we minimize the amount of contaminated sediments that are released into the surrounding waters. We also offer mechanical dredgers to meet the needs of your projects.
