Curb inlets

Details

An Essential Starting Point for Many Stormwater Systems

Reduce Infrastructure and Property Damage

Inlets prevent flooding and reduce the risk of damage to infrastructure and property by collecting and conveying surface runoff away from impervious surfaces.

Highly Flexible Design

Precast concrete curb inlets are highly flexible and can be customized to meet the specific needs of a project, including size, shape, and inlet/outlet configurations.

Optional Pollution Controls

Pollution control options can include debris inserts, oil dams, oil-stop valves, and backflow prevention.

Watertight Performance

Watertight performance is guaranteed with tight tolerances and gasketed joints.

Details

ParkUSA precast concrete inlets are an essential element of stormwater management systems. They collect water from impervious areas such as parking lots and roadways to prevent flooding and minimize damage to infrastructure and property. Curb inlets are typically rectangular or trapezoidal in shape and fit within the curb line.

The inlet opening is covered with a grate or filter to prevent debris and other materials from entering the stormwater conveyance system. ParkUSA offers grate and cover options made of cast iron or ductile iron, including city logos, and various city and state models and sizes for quick shipment.

The collected water is transported through underground pipes or discharged directly into a nearby water body to prevent damage. Curb inlets also play a critical role in enhancing water quality by capturing and filtering out debris and pollutants present in the stormwater runoff.

How It Works

Inlets are an essential component of a stormwater system and function by collecting and transporting water from the surface of roads and other impervious surfaces. Typically installed in curb lines or along the sides of roads, inlets are designed to manage and control the flow of water during rain events.

Inlets are typically round or rectangular in shape and have a grate or other type of cover to prevent debris and other materials from entering the conveyance system. The main function of inlets is to prevent flooding and reduce the risk of damage to infrastructure and property by collecting and conveying surface runoff away from impervious surfaces. Inlets also play a critical role in improving water quality by capturing and filtering out debris and pollutants that may be present in the runoff.

About the Type A Curb Inlet

The ParkUSA Model CBTA Inlet is made of precast concrete and consists of a square or rectangular box with an open top, a bottom flange iron frame, and a traffic-rated cast iron or ductile iron grate to allow stormwater runoff to enter while preventing coarse debris from entering the system. The perimeter walls contain thin-wall knockouts for connecting pipes for stormwater conveyance. The catch basin is available in different sizes and configurations to meet most application demands and municipal codes.

Applications

ParkUSA’s precast concrete curb inlets are an essential component of a stormwater system and function by collecting and transporting water from the surface of roads and other impervious surfaces.

Parking Lots

Catch basins are commonly installed in parking lots to collect and remove surface runoff and prevent flooding. They are placed strategically at low points in the system and can handle heavy loads from vehicles.

Streets and Highways

Catch basins are also commonly used in streets and highways to manage stormwater runoff. They are placed at intervals along the road to collect and remove surface runoff and prevent flooding.

Residential Areas

Catch basins are used in residential areas to collect and manage surface runoff from downspouts, planter areas, and landscape sections. They help prevent flooding and protect properties from water damage caused by excessive rainwater or irrigation.

Commercial Areas

Catch basins are installed in commercial areas, such as shopping centers, to manage stormwater runoff from large, paved areas. They can handle heavy loads and are designed to capture and filter out debris and pollutants present in the runoff.

Industrial Sites

Catch basins are used in industrial sites to collect and manage surface runoff from manufacturing processes and large paved areas. They are designed to handle heavy loads and capture pollutants present in the runoff.
