How to Improve Backyard Water Drainage

Overview

If a good, strong rain turns your backyard into a swampy mess, the answer is to move the water. And while you could spend your time in your backyard with a bucket, bailing the water like a pirate in a leaky boat, it is simpler to build a drain and let gravity do the work for you. A French drain is simple enough to build that you don't need to be an expert plumber to install it. However, it will take a degree of physical fitness and a willing to invest sweat equity into your yard.

Step 1

Draw trees and other obstacles onto your topographic map. This will save you labor by avoiding these as you dig.

Step 2

Sketch out your path for your drain. Your drain should slope away from the spot where water collects so that gravity will take the water away from your location.

Step 3

Mark your drain path through your yard with spray paint.

Step 4

Dig a trench over this path that is 12 inches deep and 6 inches wide.

Step 5

Place a 2-inch layer of gravel at the bottom of this trench.

Step 6

Insert your pipe into the trench. Turn the holes in the pipe downward so that they face the bottom of the trench and do not fill with debris.

Step 7

Cover the pipe with gravel by filling the trench to a point 3 inches from the surface.

Step 8

Add a 2-inch layer of sand over the gravel.

Step 9

Fill the remaining 1 inch of the trench with topsoil.

Step 10

Place a layer of sod over the topsoil to hide the presence of the trench.
