Direct discharge of roof runoff to grass lawns by using an ejector connected to the Splash Pad G rass downspout and splash pad with a slope away from the building is one of the solutions in residential areas. Infiltration Trench & Perforated Catch Perforated Pipe Basin Perforated Catch Basin Perforated Catch Basin Subsurface infiltration structures, soakaways, are the most common types of infiltration systems. They are basically holes in the ground filled with rubble or stones. The stormwater is stored Gravel Filling temporarily in the cavities between the Cover stones while it slowly percolates into the Downspout surrounding soil. They are typically long and narrow to Overflow Pipe minimize the surface area at the bottom that is supposed to clog with fines after some Filter time, and to maximize the ratio between the Gravel Filling effective infiltration area (the sides) and the volume.

Coarse Sand

Permeable Pavement

Road drainage through permeable asphalt Permeable Asphalt and use of the sub-base for water storage Sub-base Gravel has shown to be rather efficient in (Storage) connection with roads for light traffic.

Undisturbed Sub-soil

Retention Pond During heavy rain stormwater can be stored Evaporation in the basin, and slowly infiltrate through the soil layer and also slowly evaporate through water surface. This type of Infiltration Facility Sedimentation facilities frequently suffers severe clogging, Basin so that proper and periodical maintenance is crucial. Infiltration
