![]() ![]() Barge and equipment can be moved using a new hydro mast. The cutter head is controlled hydraulically and can be moved up or down by the barge operator. And then simply remove the bag with a special rollback truck and container. The solid material that is pumped from the pond, dry in the bag. The vacuum pump drives the silt, sand and waste into a Geo-bag located elsewhere. Geo-bag is a very big factor in this process. It works more like a vacuum cleaner to suck up and filter the bottom to remove contaminants and create depth. Hydraulic dredging doesn’t use a “scoop” to remove the silt. Cleaner water and a healthier ecosystem, increasing property values.Cost of up to 75% less than mechanical dredging.Reduction of toxic gases, weeds, and algae.Rebuilding of the natural bottom without disturbing existing water life.It can also remove loose clay, rocks, and sand, freeing up covered springs, irrigation systems, culverts, and cisterns. The bottom is restored to its original depth. This not only removes the sediments, but also the toxic gases, nutrients, and foul odors caused by the decomposition of the organic sediments by anaerobic bacteria. High-volume suction pumps are used with a suction head to remove the bottom sediments. It’s a great alternative to traditional dredging techniques. The SRS of Ohio approach to restoring ponds is environmentally friendly, far less invasive, and leaves little to no ecological footprint behind unlike commercial dredging. Later the dry material can be hauled away usually at a fraction of the cost of hauling wet material. This container passively filters out the water allowing the sediment to completely dry. The sediment is simply pumped to another location, either allowed to be absorbed into the surrounding landscape or contained within a geotextile container. SRS uses scuba divers and high-volume suction pumps to suck the sediment out without harmful repercussions of conventional dredging. If a pond is periodically maintained through hydro-raking, the need to perform a large-scale dredge project may be eliminated, and ecological disruptions can be minimized. Hydro-raking can effectively target organic sediment accumulations in coves and other shallow areas that provide nursery sites for aquatic plants and algae. Hydro Raking a very efficient for removing aquatic vegetation and debris from pond and lake. It is capable of removing accumulated muck in water as shallow as 18 inches. The hydro-rake is a floating barge upon which a backhoe is mounted with a digging bucket or rake. This method is frequently chosen as a method to remove nuisance aquatic vegetation, root structures, debris, and soft organic sediment on a smaller scale waterbody. ![]() So the excavated materials should be relocated far from the pond. For large ponds and lakes, a mechanical excavator is the best way to go.Īgain, once the dredging is finished, the sediments can settle back to the bottom of the pond, and much of the dredging benefits are lost. A mechanical excavator can remove soil and help regain the original depth of the pond.įor a small pond, hand excavation tools can be used. In this method, the pond should be drained completely and all aquatic life must either be relocated or killed off. Mechanical dredging is a very old solution for removing muck, weeds, sediment, and other harmful materials from your pond. Too much organic sludge build-up can produce a filthy odor Methods of Pond Dredging Mechanical Dredging ![]() ![]() There is likely a substance imbalance or build-up of waste causing the problem. If you find your pond water smelling unpleasant, the harmful byproducts that create when organic matter decomposes have reached a critical level. Such dirty water negatively affects the fish as well as the surrounding areas. When the water takes longer than usual to clear after a heavy rain, it’s a sure sign that the pond needs dredging. Brown pond water is a sign of low water depth in the pond Low Water Transparencyĭirty or murky water is another sign that the sediment at the bottom of the pond needs to be removed. The increased phosphate levels that are created when organic matter starts decaying will start a chain reaction of plant and algae growth that cannot be reversed by any other means effectively other than dredging. When the entire pond starts to grow more weed, it’s time to dredge it. You can clearly see excessive aquatic weed growth in the shallow area. Emergent pond plants are a clear sign of shallow depth. If too many emergent pondweed growths are noticeable then it is a clear sign that the pond has lost its depth. If your pond needs dredging, then you will see the following signs – Excessive Weed Growth
