ABSTRACT:
An improved catch basin is constituted by a cylindrical container with a partition dividing the internal volume into a lower compartment and an upper compartment. The partition includes an intake region and an outlet region, each communicating with a vertical pipe extending downwardly from the partition and opening into the lower treatment chamber at an intermediate location therein, the intake region and the outlet region being diametrically opposite one another. The partition defines a central, oblique ramp which urges entering liquid in the direction of the intake opening of the intake region. Thus, under conditions of low liquid flow into the catch basin, all entering liquid will be directed to the intake region, descending along the intake conduit and into the lower compartment. Conversely, under conditions of high liquid flow into the catch basin, a portion of the liquid will overrun the ramp and gain direct access to the outlet region, from which it will exit the catch basin.
