What is Dredging?

Dredging is the process of removing sediment and residual debris from a body of water. Over time sediment can build up and be harmful to the health of a body of water. The National Ocean Service explains dredging is, “routine necessity in waterways around the world because sedimentation—the natural process of sand and silt washing downstream…” Dredging can benefit: lagoons, storm water detention ponds, dredge sediment lagoons, marinas, golf course ponds, canals, and home association lakes.

In order to have a robust, livable body of water it is important to regularly remove the sediment, debris and underwater plants which build up over time. An excess of sediment creates a murky, dirty, and eventually lifeless pond. A marine biology study conducted by Extension, an arm of Michigan State and their nature research programs, explains,

“If dredging your pond beyond the photic zone to reduce plant growth is what you desire, then dredging will help. If dredging to 15 feet or more to improve fish habitat is what you desire, then dredging will help.”

It goes on to detail, “(d)redging can also remove muck and sediment during the process, as well as provide a better habitat for fish.”  In order to maintain a well-kept body of water over time it is essential to regularly have it dredged as sediment builds up.


How often should I dredge?

A recent pond health study done by Clemson indicates that sediment removal should be done by the time sediment begins to build up to about half of the average depth of the pond. The frequency a body of water is to be dredge is not based on a time frame, but rather water quality and sediment build up as each one is different.


Depending on the type of run off  sediment in the body of water, sediment building up to becoming half or more of a pond is not unusual to see occur relatively often. Three key factors to look at when evaluating if it is time to dredge include:

  1.  Is mud/sediment easily stirred up with activity (such as boats entering or leaving the water) around the shallower sections of water?
  2. How is the water quality? Does it take a while for the body of water to clear up after a storm?
  3. Is the body of water having problems irrigating?

If one or more of these issues describe your body of water then it may be time to dredge.


Where we come in.

At 3R, we have the skills, the know-how, and the right tools for nearly any dredging job. We take our state of the art equipment and a highly professional approach to dredging services to provide a job well done on time and under budget. An example of 3R's great equipment is our Dino Six Dredge. Our DINO Six is a uniquely portable dredge system developed to perform jobs inaccessible to other dredges and sediment removal equipment.


For more information on our Dredge and the capabilities of this great piece of equipment, see Dino Six Dredge.


Sediment-Free System

Dino Six Dredge: One of our state of the art pieces of equipment to provide top-tier dredging services!Our Dino Six Sediment Free System features a cutter head that is designed for minimum disturbance of the water column and keeps total suspended solids to a minimum resulting in a minimum risk to fish and other marine life and lower TSS discharge.  Our system utilizes a compact lightweight hydraulic dredge that is 21 feet long. This allows us to perform in places that are inaccessible to conventional dredging equipment as well as keep our mobilization costs low. To the right is a picture of this cutting edge equipment.


We can perform numerous tasks that excavators and ordinary hydraulic dredges simply cannot access. When sediment removal is complete there is virtually no need for site restoration. The lightweight equipment does not disturb the ground or tear up sod. Even a golf course can stay fully functioning during the dredge operation. In the past, the drawback to sediment removal in ponds and lagoons has been controlling the excess water without making a huge mess.



Benefits of the Sediment-Free System:

  • Allows you to continue your daily operations with minimal interruption.
  • Lower mobilization costs.
  • Availability to areas with limited access.
  • No need for mechanical dewatering.
  • Safe for rubber pond liners.
  • Clean water returns to waterway.
  • Minimal site impact.
  • Quick site turn around.
  • Use of Envirotubes TM greatly reduces haul off costs.


Whether it is to clean and or deepen an industrial pond, to beautify your home, or any other dredging need that may arise we are the company for the job! We are offering dredging  Services in Upstate South Carolina and the Southeastern United States.
