Marine Dewatering

This town in North Carolina needed it’s canal system dredged to provide homeowners with better boat passage from their homes to the larger bodies of water for fishing and recreation. State regulations required the dredge water meet stringent requirements before it was returned to the canal. WaterSolve successfully chemically treated and settled this water to meet the regulations and keep the dredge operating in compliance.

A build-up of organics, sediments, very fine silt and clay created a major navigational problem for members of the Queens Lake Marina Association, in York County, VA. A contract was issued to dredge and dewater sediments in the boat slips and outside the enclosed slip area.

The Whitefish River was contaminated with diesel oil and solvents. Clearwater Dewatering of Nampa, Idaho and WaterSolve, LLC worked with Rocky Mountain Dredging, LLC for the dewatering of the solids. The project began in September 2010.

WaterSolve, LLC was chosen to assist in this project involving the dredging of the Grand Calumet River. The goal was the removal of contaminated sediment from a one-mile section of the river where it flows through one of the most industrialized areas in the country.  WaterSolve, LLC was contracted to provide automated chemical treatment, and monitoring, of the dredged material as it was pumped into Geotextile Tube containers.

A community college near Key West, Florida needed to dredge and deepen their lagoon used for training diving and rescue workers. The lagoon was located in an environmentally sensitive area. The permit limitations included strict turbidity limitations as well as residual polymer restrictions. WaterSolve, LLC was contracted to provide the equipment, products, and training to perform the chemical conditioning to dewater thE dredged material in geotextile containers. WaterSolve, LLC facilitated the approval of the recommended chemicals through marine toxicity testing and also completed the residual polymer testing during the project implementation.

WaterSolve was contracted to provide personnel, dredging, equipment and products for a refinery that had to empty a lagoon and its residuals.  Over 25,000 cubic yards of residuals were removed from the lagoon and dewatered to pass the paint filter test.

At a Naval Air Station the portion of the seaplane lagoon was contaminated by hazardous materials. This hazardous material was being disposed of into storm water drain that discharged into the lagoon.

Removal of PCB laden creek:  The objective was to dredge and dewater the sediments from the creek. Due to the various depth changes in the creek the contractor used a raft for the hydraulic pump, and the workers used suction hoses to remove the residual.  

Geotextile tube containers were used to remove contaminated sediment from a lake in California. WaterSolve, LLC was tasked to provide a Geotextile dewatering system and onsite personnel for this project.

Approximately 2,650 cubic yards of sediment from a reservoir and alum sludge pond in New York were dredged into Geotextile containers. WaterSolve LLC provided the equipment, polymer, Geotextile tube containers, and technical support of this project.

A community college near Key West, Florida needed to dredge and deepen their lagoon used for training diving and rescue workers.  The lagoon was located in an environmentally sensitive area.  WaterSolve, LLC was contracted to provide the equipment, products, and training to perform the chemical conditioning to dewater the dredged material in geotextile containers.

A crude  oil pipeline ruptured in Southwest Michigan, resulting  in crude oil sediment that needed to be dredged from a river. WaterSolve was contracted to provide the chemical treatment, equipment, and personnel to flocculate the residual as it was pumped to geotextile tubes.

This coal fired electric power plant in Minnesota had a sediment pond full of solids and in need of dredging. The landfill nearby was closing and they needed to dewater and transfer the residual quickly. Geotextile tube dewatering technology was tested and selected by facility managers for its low cost, high volume, and quick drydown of the residual.

A lake located on the eastern side of New York was to be dredged in order to remove contaminated sediment. The dredged material needed to be captured and dewatered before it could be transported to a landfill for permanent placement. WaterSolve LLC was tasked to provide the Geotextile Tube containers, chemistry, chemical feed equipment, and technical assistance to dewater the dredged sediment for the start-up of this project.

A Wastewater Treatment Plant in New York is responsible for handling iron waste from their multiple facilities.  In order to process the iron waste, the water treatment plant had to backwash 25,000-50,000 gallons of residual to settling ponds located on site. These settling ponds became saturated with iron backwash residual.

During construction of a new bridge footing in the Petaluma River, a slurry seal was poured into a caisson and did not properly set.  The contractor was required to dredge out the slurry seal prior to attempting another pour and sufficiently dewater the slurry so it could be hauled off-site.

WaterSolve, LLC works with the USACE and USEPA on a superfund project to remove over 30,000-cubic yards of contaminated sediment using Geotextile tube containers.

This reclamation project in New York required three pits to be cleaned and dewatered so the lead impacted sediment could be sent to a landfill.

Geotextile containers were selected to dewater the contaminated residuals being pumped and from this raceway and underground tunnels in Massachusetts. The residuals from the dredge were pumped and chemically treated to  a primary Geotextile Tube and the filtrate was pumped and chemically treated again as it was sent to a secondary tube. This filtrate was then sent to a water treatment plant on site and discharged into the river.

After mechanically removing coal residual from this lake a dredge vacuumed the silt on the floor of the lake and pumped the material to Geotextile Tubes to capture and dewater the solids.

Lake with 1,200 cubic yards of sediment needed to be dredged and dewatered.
