Stormwater utilities are designed to handle rainwater that runs off surfaces like roads, parking lots, and buildings. Their job is to prevent flooding and keep our water clean. East Coast Civil Group has an established reputation for quality in the construction and installation of stormwater utility systems around Raleigh, NC.
As an established civil contractor, East Coast Civil Group is responsible for the physical construction of stormwater utilities. This involves excavation, grading, installation of pipes and stormwater management structures, and the construction of detention or retention basins.
Our civil contracting crews implement erosion control measures to prevent sediment and pollutants from entering stormwater runoff during construction. This may involve installing silt fences, sediment basins, and other erosion control techniques to protect water quality.
East Coast Civil Group fulfills a vital role in the construction of stormwater utilities by ensuring that stormwater is effectively managed, and infrastructure is built to meet regulatory standards.
Stormwater utilities come in different types, each with its own way of handling stormwater:
Stormwater Pipes and Drains:
Underground pipes and drains are used to convey stormwater from impervious surfaces (such as roads, parking lots, and rooftops) to suitable discharge points, such as underground detention systems or retention basins.
Detention Basins:
Detention basins temporarily store stormwater runoff and release it slowly, reducing the peak flow into downstream areas. This helps prevent flooding and allows sediment and pollutants to settle out before discharge.
Retention Ponds:
Retention ponds hold stormwater runoff for a more extended period than detention basins. They typically have a permanent pool of water, and their primary function is to improve water quality by allowing pollutants to settle and degrade.
Biofiltration Systems:
These systems, such as bioinfiltration basins and bioretention cells, use vegetation and engineered soils to filter and treat stormwater runoff. They help remove pollutants and improve water quality.
Permeable Pavements:
Permeable or porous pavements allow stormwater to infiltrate through the surface and into the ground, reducing runoff. These pavements are commonly used in parking lots, sidewalks, and driveways.
Stormwater Wetlands:
Constructed wetlands mimic natural wetland ecosystems and provide habitat for wildlife while treating stormwater by promoting natural processes like sedimentation and nutrient removal.
Stormwater Filtration Systems:
These systems use a combination of physical, chemical, and biological processes to remove pollutants from stormwater runoff. They often incorporate media like sand, gravel, or specialized filter materials.
Infiltration Trenches:
Infiltration trenches are underground structures filled with aggregate materials that allow stormwater to infiltrate into the ground. They are effective at recharging groundwater and reducing runoff.
Swales:
Swales are shallow, vegetated channels designed to slow down and filter stormwater runoff. They can be constructed in urban areas to manage runoff from roads and parking lots.
Stormwater Pump Stations:
In areas with low or flat topography, pump stations may be necessary to lift stormwater to a higher elevation or convey it to an outfall point.
Stormwater Management Ponds:
These are large, engineered ponds designed to store and treat stormwater runoff. They can serve multiple purposes, including flood control, water quality improvement, and recreation.
Combined Sewer Overflow (CSO) Control Facilities:
In older urban areas with combined sewers, CSO control facilities are designed to capture and treat stormwater and wastewater to prevent overflows into receiving waters during heavy storms.
