This supplimental drainage device was designed as an alternative to conventional weep-holes to allow streets to drain into the storm drain system when the asphalt is held down and / or prior to the surface lift of asphalt.
The StreetScaper drainage device provides an unobstructed method to allow water to drain quickly and enter the storm drain system. It is easily maintained and does not require patching prior to final paving.
Although it is not necessary to install at every curb inlet, it is recommended for low areas and at multiple curb inlets draining in that direction. Reducing the velocity will improve its efficiency.
