Channel Drains

A channel drain, also called a trench drain, catches water along the edge of a driveway, patio or pool deck before it pools. We stock the NDS Pro Series 5 in. system: complete kits, bulk packs and couplings for curves.

Which NDS Pro Series Channel Drain Do I Need?

Pick the grate for the traffic, then buy enough kits for the length. Every kit uses the same 5 in. wide, 1 meter channel, so you can mix packs on one job.

How to Install a Channel Drain

  1. Dig: cut a trench along the low edge of the slab, driveway or patio.
  2. Assemble: snap the channels together and add the end cap and end outlet. Side or bottom outlets can go anywhere along the run.
  3. Connect: run drain pipe from the outlet to a safe discharge point.
  4. Set: bed the channel so the grate sits flush with the surface, then fasten the grates.

For base, bedding and outlet details, see our channel drain installation guide.

Where Does the Water Go?

A channel drain only collects water. Send it downhill to daylight or a storm drain, into a Flo-Well dry well when there is no outlet, or through a gravel-free EZ-Flow French drain. For low spots in the lawn, pair it with catch basins and yard drains.

Channel Drain FAQs

Is a channel drain the same as a trench drain?

Yes. The two names are used interchangeably for a long, narrow grated channel set flush with the surface to catch water along its whole length.

Can you drive over a channel drain?

It depends on the grate. The Pro Series kit with galvanized steel grates is NDS Class B medium duty, rated for autos and light trucks with pneumatic tires under 20 mph. The light-traffic plastic grates in the 9-pack are for patios, pool decks and walkways.

How much channel drain do I need?

Measure the edge you need to drain. Each Pro Series kit is 1 meter (about 3.3 ft), so a 3-pack covers about 9.8 ft and a 9-pack about 29.5 ft. The last channel can be cut down to as short as 4 in.

Can a channel drain go around a curve?

Yes. NDS Qwik-Turn 864 radius couplings snap between channels and rotate up to 6 degrees each, for bends as small as a 30 in. radius. For sharp 45 or 90 degree corners, NDS makes separate elbows.
