Dig a Trench

The trench should be about 18 inches deep and 9 to 12 inches wide. French drains need to have a slope of at least 1 percent, so the force of gravity will work for you. This means that the drain should slope down a total of at least one inch for every 10 feet of pipe.

How deep should I bury drainage pipe?

Maintaining a depth of 12 to 18 inches is best for drain pipes, but the depth of the pipe may vary in order to maintain a downward slope, which is critical for proper drain functioning.

How long will PVC pipe last underground?

Which is stronger PVC or corrugated pipe?

Pros of solid PVC pipe:

Durability: This type of pipe is much more durable than corrugated pipe – it isn’t penetrable by roots and is simple to unclog. Smooth walls: The walls of PVC pipe are smooth, so it is less likely to clog or to catch debris that slows water flow.
