PORTFOLIO SERVICES ABOUT CONTACT SERVICES DREDGING Sediment buildup impairs the natural hydraulics and ecology within water bodies, and is often contaminated, posing environmental risks. Dredging is integral to a variety of ecological improvement projects, removing and managing unwanted sediment. Dredging can be an effective solution to restore flow, improve water quality, and increase benthic habitat, benefiting aquatic ecosystems while improving surface water aesthetics and reducing flood risks. SumCo Eco-Contracting’s dredging experience includes harbor, river, channel, stream, creek, pond, lake, wetland, marsh and bog dredges for private clients and municipal, state and federal agencies. We are experienced in technical water control methods, sediment disposal/deposition, and working in and around fragile resource areas to restore bodies of water.

PORTFOLIO SERVICES ABOUT CONTACT SERVICES DRAINAGE IMPROVEMENTS Control of stormwater is vital to maintaining ecology and resilience, whether in pavement-laden urbanized settings or rural or coastal resource areas. We excel in constructing nature-based designs that use natural systems to address flooding and erosion hazards. Nature-based solutions enhance safety, minimize future infrastructure costs, and secure natural resources benefits for communities and the natural world. Effective drainage systems reduce the risk of damaging flooding from storm events and control and treat runoff- before it enters the surrounding environment. Well-designed and constructed stormwater management systems mitigate both the quantity and quality of stormwater caused by runoff from impervious surfaces. SumCo Eco-Contracting has a wide range of experience in constructing various drainage improvement projects. Examples of these projects include construction of stormdrains, catch basins, channels, bioretention swales, infiltration chambers, and various other stormwater drainage infrastructure best management practices (BMP).
