Abstract:
A pre-cast reinforced concrete catch-basin of larger than conventional catch-basin dimensions includes a solid horizontal bottom wall with solid, hollow, cylindrical side wall upstanding therefrom to about half the height of the catch-basin. The lower half thus forms a sealed, unapertured, undrained, sump receptacle for collecting drain water and silt and allowing sand to settle out. The hollow, cylindrical, upper half contains leaching openings which extend through from the inside to the outside of the wall, from top to bottom, for discharging cleared water to the surrounding, stone-lined, earth without plugging, or clogging, and without polluting nearby wells, brooks, etc.
