Draining areas filled with heavy mulch is no problem for the 6 in. Atrium Drain Grate. Leaves, mulch, and debris are trapped at the base, while the raised dome grate continues to drain water through from the top into drain pipe. The specially designed drain grate is designed to handle moderate flows of stormwater in mulched landscape beds, natural areas, and window wells. The 6 in. atrium dome drain grate has an open surface area of 28.0 sq. in. and a flow rate of 87 GPM. Connects to Spee-D Catch Basin Drain, 6 in. sewer and drain pipe & fittings, & 6 in. single-wall corrugated pipe for a soil-tight fit. Built to stand up to the elements, the drain grate (or drain cover) is made of polyethylene, a type of plastic, using a combination of virgin and recycled content treated with UV inhibitors to prevent fading and cracking from the sun. As part of a complete drainage system, the grate blocks mulch, leaves, and debris as it drains water entering drain pipes. The pipes carry the water to a discharge point downstream such as a pop-up emitter, or percolates into the ground with a dry well or infiltration trench. NDS offers free tools such as the Home Drainage Center, Calculators, and NDS Stormwater Drainage mobile app to help make your project a success. Founded in 1972, NDS is the preferred choice of professionals and the leader in stormwater management solutions.
