Trenchlesspedia explains Catch Basin

Catch basins -- the grated "storm drains" seen on the side of roadways and in other locations -- may be installed under state, county or other municipal construction projects. Catch basins can also be installed in areas of private lands or roads to prevent precipitation events from covering the lands or roadways with water. These reservoirs catch drainage water or storm runoff to prevent flooding.
