The largest catch basin in the lineup, the 24 in. Square Catch Basin Kit with grate and outlet adapters is designed for managing heavy flows from lawns, landscaped areas, parks, driveways, and courtyards. Promotes healthy lawns and landscapes, reduces slip hazards, and prevents erosion which can lead to costly property damage. Stormwater catch basins are designed to efficiently drain away water where it doesn't need to be. As part of a complete drainage system, the catch basin collects and directs water to connected drain pipes which carry the water to a discharge point such as a pop-up emitter, or to percolate into the ground with a dry well or infiltration trench. Basin Kit includes a 2-opening polyethylene basin, 3-outlet adapters, 2-reducer rings, 1-plug, and a polyethylene grate to block leaves and debris from entering the drainage system. Basin Kit connects to 8 in., 10 in., and 12 in. drain pipes with included outlet adapter and reducer ring. The storm drain with grate is rated for NDS Class B loads when properly installed. Built-in basin sump is easy to access and clean. 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 with proven products, tools, and support to help you get the job done right.
