suction dredging

How can suction dredging help you?

Is your lakefront or pond filled with muck and decomposing leaves or vegetation? Do you remember when you bought the house twenty years ago and the bottom was firm and deeper? Maybe your pond used to be deeper and now it looks more like a swamp with excessive aquatic pond weed growth? Essentially, what you are witnessing is called eutrophication. The term eutrophication, can refer to a natural process or a natural process influenced by human activities. Suction dredging is likely the answer to your problems.

suction dredging

Like hydraulic dredging, suction dredging is a process by which organic and some inorganic sediment can literally be sucked out of your pond or lake. This is where any comparison ends. Hydraulic dredging utilizes large barges (typically 40’ and larger) and an auger which is a mechanical apparatus that grinds and chews through sediment, which is ultimately captured and pumped out of a body of water using suction.

The auger or cutting head is less than environmentally friendly. While more invasive, every method has its place and this solution can be the right choice for very large commercial applications. However, for the private homeowner, lake association, beach club, marina, golf course, municipality, preservation society or property management firm, this is not an attractive, affordable, or even preferable option. Try for a moment to imagine taking a small hydraulic dredge, lifting it with a crane up and over your home, and then dropping it into your pond. Let’s take it a step further. Let’s now try to imagine digging a 40′ deep hole in your yard and pumping sludge and water into the hole. These aspects are part of your typical hydraulic dredging job. Finally, think of the auger head of a hydraulic dredging chewing through the clay liner of your pond, displacing or “eliminating” native flora and fauna, and potentially even rupturing the pond. While this is uncommon, it is a risk when dealing with a less than careful operator. Once you rupture a pond basin, the cost to repair the crack and the rest of your property (from all the heavy excavation equipment driving back and forth) can make the dredging project cost look far less intimidating.

restore your waterfront

In years gone by, it was necessary to remove accumulated sediment with heavy and imprecise construction equipment (large backhoes and excavators) or massive barges with a cutting head that can do significant damage to the natural bottom of a body of water. There is a better solution, and we can help.

Pristine Waters is the local dredging company with the experience and equipment to reclaim lakes and ponds. Our methodology delivers impressive results. What makes it truly unique is the small, both physical and environmental, footprint that it has. The equipment we use is easily navigable through almost any backyard to the body of water, with no damage to property.

Contact us today to learn about Pristine Waterfronts sediment suction dredging restoration methods and how we can help restore your pond, lake, or other waterway. Our suction dredging service utilizes small, yet highly effective equipment, to remove organic and inorganic sediment(muck) from ponds and lake waterfronts. Additionally, we remove silt, algae, invasive native and non-native aquatic vegetation, and other debris. We do these things using pumps, hose, and other portable equipment to offer a cleaner, more eco-friendly form of dredging. No traditional “digging” is required! Our land based dredge is comprised of a robust mining pump and a relatively small diesel engine mounted on a small trailer, making it uniquely portable and maneuverable to get into areas other equipment cannot. This makes removal of various types of sediments easy to manage. A quick review of small dredges makes it clear that our equipment is vastly superior to that of many of our competitors.

how pristine waters is different

By utilizing divers that can determine where the natural pond or lake bottom begins and the sand, silt, or muck ends, we eliminate much of the environmental impact to the wildlife that typically accompanies manual and hydraulic dredging. Our skilled technicians use a hose attached to a high-pressure pump system to vacuum up the sediment, which is then transferred to land and into a dewatering bag (or “geotextile tube”). These micro-porous bags will allow the water to return to the pond or lake, while capturing the sediment for eventual re-purposing or removal and disposal. Our turbidity curtains help to make sure that the work being done on your property does not effect other property owners. Our very short set-up and breakdown times (including placement of the dewatering bag) mean that we cost less and we pass that saving along to you. Additionally, the faster we complete a job, the faster the dredged solids can settle and water can be returned, the faster the removal process can start. Once fully de-watered and the bag has been removed, the site is now ready for some very simple and easy lawn repair.

Typical issues that can come up during the permitting process focuses on disturbances in the water and on the land. Our approach offers the means to remove accumulated organic and inorganic sediment with a minor, short term impact in the water. As we don’t move large amounts of material at any given time, we can then manage what we move up land with minimal impact and relative ease. Less disturbance means a greater likelihood of successfully obtaining a permit. Utilizing our compact, yet highly efficient, portable dredging equipment, we can often do jobs that other companies cannot. Our system is efficient, relatively non-invasive, and very fast.

Pond dredging requires a unique restorative approach to avoid damage to your landscaped property. You should not need to spend large sums of money to fix your landscaping after spending money to fix your pond. Our approach will minimize these unnecessary repairs and reduce your aggregate cost versus the alternatives. Unlike waterfront or lake dredging, pond dredging will likely require taking greater amounts of sediment in specific areas of the pond due to the smaller size of the basin and generally more “static” waters found in ponds. While quantities may be greater, this also usually results in more efficient suction dredging projects, as we spend more time working in specific locations within the pond and less time moving equipment around.

There are specific challenges to dredging a waterfront or section of a lake that inherently, require a slightly different approach.
