Drains or inlets appearing in ditches and medians are usually grate inlets and are also termed “drop inlets.” The operation of the inlet is enhanced by a concrete riprap collar that forms a type of bowl around the inlet.

Stormwater Studio has the ability to design and analyze a system of inlets along with your underground pipe system. It has built-in capability to analyze the following inlet types: Inlets are located at the upstream end of a Line and can be in a sag or …

Stormwater inlets—also known as storm drain inlets, curb inlets or catch basins—are inlets to storm drain systems. Communities can use a range of stormwater controls for these inlets: products that capture floatable and settleable pollutants such as oil, grease, trash and coarse sediments at the inflow. These controls are

Most aspects of storm drain design such as system planning, pavement drainage, gutter flow calculations, inlet spacing, pipe sizing, and hydraulic grade line calculations are included in this chapter. The design of a drainage system must address the needs of the traveling public as well as those of the local community through which it passes.
