10 Sep Krispen Drain Dredging
Do you know about Krispin Drain Dredging? One of our fantastic customers, J.F. Brennan Construction, recently began a project to restore the Krispin Drain on Harsens Island in St Clair County, Michigan. The project involves dredging and reshaping the 4-mile drain while restoring natural vegetation and eliminating invasive plant species.
Marsh Buggies is proud to have its machines and products play such an integral role in this project’s success. Way to go Brennan!
There are many benefits to dredging.
Dredging is the removal of sediments and debris from the bottom of lakes, rivers, harbors, and other water bodies. It is a routine necessity in waterways around the world because sedimentation—the natural process of sand and silt washing downstream—gradually fills channels and harbors.
Dredging is often focused on maintaining or increasing the depth of navigation channels, anchorages, or berthing areas to ensure the safe passage of boats and ships. Vessels require a certain amount of water in order to float and not touch bottom. This water depth continues to increase over time as larger and larger ships are deployed. Since massive ships carry the bulk of the goods imported into the country, dredging plays a vital role in the nation’s economy.
Dredging is also performed to reduce the exposure of fish, wildlife, and people to contaminants and to prevent the spread of contaminants to other areas of the water body. This environmental dredging is often necessary because sediments in and around cities and industrial areas are frequently contaminated with a variety of pollutants. These pollutants are introduced to waterways from point sources such as sewer overflows, municipal and industrial discharges, and spills; or may be introduced from nonpoint sources such as surface runoff and atmospheric deposition.
The disposal of dredged material is managed and carried out by federal, state, and local governments, as well as by private entities such as port authorities. The U.S. Army Corps of Engineers issues permits for the disposal of dredged material; the U.S. Environmental Protection Agency provides oversight and authorization for the disposal of dredged materials.
