A domed grate is typically used for larger sized areas of flower beds that are mulched where floating debris could block a flat grate. Grate can be directly attached to drainage pipe where a catch basin is not appropriate or feasible. 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. This style of grate is not recommended for any areas exposed to traffic. Also may be used with a 6" round catch basin where appropriate. The function of the catch basin is to collect sediment in it's sump area and not allow this sediment to enter and plug the drainage pipe.
