When stormwater causes flooding on playgrounds and playing fields, or in parking lots and shopping plazas, it's a sign the excess water isn't able to properly drain. If the problem isn't fixed, it can lead to safety hazards and sinkholes, not to mention eroding asphalt and costly damage to the property. Here's what you need to do. Capture heavy stormwater flows right from the surface with the 18 in. Catch Basin Drain. As part of a complete drainage system, the catch basin collects water and directs it to connected drain pipes; the pipes carry the water to a discharge point downstream such as a pop-up emitter, or to percolate into the ground with a dry well or infiltration trench. The large catch basin is made with polyethylene and built tough to handle the demands of residential, commercial, and industrial environments. Connects to 3 in. - 8 in. drain pipes with designated outlet adapters (sold separately) for a soil-tight fit. Flow capacity will vary based on pipe size. Use with 18 in. catch basin drain grate (or drain cover) to block debris from entering and clogging the drainage system; load rating will vary based on grate.

Dear Valued Home Depot Customer,
We have reached out to the manufacturer and their reply is, Thanks for your comment. Yep, it's true - this catch basin works with a drain grate, which is sold separately (SKU# 1811). As stated in the product name, this item is a catch basin only. Sorry to hear about the confusion!
