Material Calculate

The downspout connection has its own sizing rules separate from the basin. This guide covers adapter fittings, connection pipe sizing, and when combining multiple downspouts requires upsizing.

Driveways concentrate runoff more than any other residential surface. This guide covers sizing by driveway type, crown vs. single-slope layouts, and when to choose a trench drain over a point basin.

A full yard drainage plan beats a one-off basin purchase. This guide walks through mapping your property, grouping drainage zones, sizing each basin, and choosing a discharge point.

Basin depth is set independently from footprint. This guide covers how pipe slope, sump depth, and local frost line determine installation depth, with a regional frost depth reference and a riser alternative.

A practical guide to NDS's catch basin lineup, from the compact 6-inch round basin to the 24-inch square option, with real GPM comparisons to help match your calculated flow rate to an actual product.

Basin shape rarely affects drainage performance, but it does affect installation and fit. This guide compares round and square catch basins for edge placement, excavation method, and site consistency.

A correctly sized catch basin can still fail with the wrong grate. This guide covers grate load classes, open area percentage, and how to match grate material to your basin and traffic type.

Basin material doesn't change your GPM requirement, but it does affect cost, weight, and load rating. This guide compares HDPE plastic, PVC, and precast concrete across real installation scenarios.

Basin spacing depends on pipe slope, not guesswork. This guide covers minimum slope requirements, spacing charts by application, and when a sump pump is needed to extend spacing on flat ground.

Basin count depends on drainage zones, not acreage alone. This guide covers how to split a larger property into zones, size each independently, and decide between fewer large basins or more small ones.
