The NDS Spee‑D 6in Round Catch Basin (SKU 300) is a compact, three‑outlet drainage basin designed to collect surface runoff and connect directly to 3" and 4" drainage pipe systems. Its sump reduces debris flow into the pipeline and simplifies routine maintenance.

  • Three-outlet design: Multiple inlets provide flexible connection options and allow the basin to act as a tee or series node in a drainage run.
  • Pipe compatibility: Fits 3" and 4" single-wall corrugated pipe, sewer & drain pipe, and 4" Schedule 40 (SCH 40) pipe for broad installation use.
  • Durable construction: Made from UV‑stabilized high-impact polystyrene (HIPS) to resist cracking and stand up to outdoor exposure.
  • Compact footprint: 6-inch round profile keeps the basin low-profile in lawns, patios, and landscaped areas while maintaining effective sump capacity.
  • Easy maintenance: Accessible sump area and removable grate make debris removal quick—inspect after heavy runoff to maintain flow capacity.
  • Grate & accessory compatibility: Accepts standard round grates, risers, and Spee‑D accessories so you can match finishes and load ratings.

Ideal for residential and light-commercial drainage projects, the NDS 300 Spee‑D basin provides a reliable, easy-to-install solution for managing standing water, downspout discharge, and landscape runoff. Always follow local codes and NDS installation instructions when integrating this basin into a drainage system.
