Stormwater Retention Pond Dredging

Whether it's a retention pond, stormwater pond or a lagoon, all ponds are in a dying process the moment they are created. Algae, weeds, leaves and other organic material travel and settle at the bottom of the pond in the form of residue, or muck.  Muck, over time, fills the pond and becomes the main source of several problems that the owners of the pond are faced with.

Made up of toxic gases and nutrients that harbor excessive algae and weed growth, muck deteriorates the pond's ecosystem. Dredging is an efficient and economical way of ridding the pond from pond scum and muck and returning it to new life.

A detention or retention pond collects and cleans storm water runoff. It is beneficial in that it helps slow the rate of runoff from storm water, protects neighborhoods from flooding and improves the quality of water that exits the pond. The pond acts as a collector to trap sediment from seeping into storm water that clogs rivers and streams, and degrades the environment for birds, fish and other wildlife.

At C&M Dredging, our eco-friendly dredging system utilizes compact, easily deployable dredging and harvesting equipment to remove accumulated sediment, sand, vegetation and debris from your storm water retention and storage area. We return your storm water system to its original design capacity, and help prepare you for Florida's storm season.

Our dewatering tubes are placed around the perimeter of your pond system to quietly, and efficiently dewater the sediment removed with the hydraulic dredging system. Rapid mobilization and non-invasive equipment are the key components to a fast, efficient and effective storm water pond or lake restoration project.

Only clean water is returned to the waterway and there is minimal need for site restoration. Our methods do not damage pond or lagoon liners and your pond is restored to its most effective, functional state.

Hurricane Damage Restoration

Florida Keys


  • Remote Island Location 3 miles from mainland in FL Keys
  • Hydraulic Dredging to Geotextile tubes
  • Automated Polymer Injection System for Material Dewatering and Clean Effluent Requirements
  • Dewatering site constructed on sectional barge at island location
  • Dredging, Dewatering, Hauling and Disposal all simultaneously
  • Geotextile tubes transported by barge back to mainland daily for offloading into trucks
  • Sensitive Marine Benthic Resource avoidance and protection integral part of project requirements


C&M Dredging performed an environmental restoration dredging project to reverse impacts caused by hurricane damage to an island resort in the Florida Keys. A canal system and basin system that was in place for barges and vessels that serviced the island resort daily had been filled in by hurricane-force winds and tidal surge.

The difficulty was that the project site was 3 miles from the mainland, on an island.
