How to Put in Water Drainage for Horse Paddocks

Updated March 23, 2017

It is essential to the health of your horses that a paddock is well drained. Those with clay and other soil structures that cause drainage difficulties run the risk of groundwater build-up. This provides an excellent breeding environment for mosquitoes and other insects and bacteria proliferation. An economical way to provide drainage in your paddock is through the use of soil strip drains, which are relatively easy to install. These products are available under brand names including TerraDrain and AkwaDrain and are generally available in rolls 6 to 36 inches wide and 100 to 500 feet long.

Measure the distance from the area you want to drain to the point of outlet. This will help you calculate how much strip drain product you will need. If you have a large surface area to drain, you can connect branch strip drains to a main strip drain with tee connectors.

Dig trenches from the area where water is collecting to the water outlet area. Trenches should be as wide and 3 inches deeper than the strip drain product. Trenches should gently slope down to the water outlet area. Strip drains can generally absorb 21 gallons per minute per foot on a 0.1 gradient. The steeper the gradient the better the absorbency rate will be.

Lay the product into the bottom of the trench and backfill the trench with sand.

Connect an outlet connector to the strip drain at the water outlet point. This will transition the collected water to a 4-inch PVC pipe. The water can then be channelled to wherever you want to collect, drain or use it.
