A flat grate that can be used for larger sized areas of grass, flower beds, patios, driveways, etc. without the need for a catch basin. Grate connects directly to drainage pipe. Excess water flows towards and through the grate and then drains directly to below grade drainage pipe that allows the water to flow to areas where excess water can be tolerated. Grate can withstand pedestrian and bicycle traffic. Also may be used with a 6″ round catch basin where appropriate. The function of the catch basin is to collect sediment in its sump area and not allow this sediment to enter and plug the drainage pipe.
