Swales are ditches or trenches built to direct and slow the flow of rainwater so that it has a chance to sink into the soil. While many gardeners dig swales on hillsides, all that is required is that the outlet on the far end of the swale is lower than the swale itself.
Constructing a Swale in 9 Steps
- Step 1: Observe water on your site.
- Step 2: Identify the ideal site for a permaculture swale.
- Step 3: Mark the contour line.
- Step 4: Dig a trench along the marked contour line.
- Step 5: Mound the soil from the trench on the downhill side to create a berm.
- Step 6: Test and adjust the swale.

A swale is a shady spot, or a sunken or marshy place. In particular, in US usage, it is a shallow channel with gently sloping sides. Such a swale may be either natural or man-made. Artificial swales are often infiltration basins, designed to manage water runoff, filter pollutants, and increase rainwater infiltration.
What is the difference between a bioswale and a rain garden?
The key difference between the two is that bioswales are designed more for cleaning and processing water as well as redirecting it (usually away from a road or lot), while rain gardens are more strictly designed to absorb stormwater, particularly off rooftops and walkways.
Where do you put a swale?
So, ideally, a swale will be installed at the highest point possible but still low enough, downslope, to catch water run-off. From here, spread the water out on level plain by extending the swale on contour for as long as possible, that way water can absorb evenly into the land downhill.
What is a swale in landscaping?
Swales can be part of an area’s natural landscaping, or they can be created to help ensure proper drainage, minimize runoff or capture storm water. In simple terms, they are generally shallow ditches that have gently sloping sides.
How do you keep water from coming down hills?
BUILD A BERM, a small hill covered with grass or other plants that will divert runoff around what you want to protect. ROUTE THE WATER INTO A DRY WELL. GRADE BROAD SURFACES to direct runoff away from houses, sheds, barns, and patios. INTERCEPT THE WATER by using a swale, a shallow ditch with gently sloping sides.
How much does it cost to build a swale?
Surface swale: Estimate at $.50 per square foot. These slightly depressed flow lines are created through grading. Surface may be lawn or cobbles to help slow velocity and filter debris. French drain: Estimate $20.00 to $30.00 per linear foot.
Does gravel help drainage?
Landscaping gravel also provides much-needed drainage so that water doesn’t collect around the roots. Gravel and stone are easy to spread and easy to maintain.

Get the bottom of the trench flat and level. Begin filling the swale. Add bulk material, like rotten wood. Add a final cover material, like straw.
Why do they put rocks in ditches?
Lining drainage ditches with rocks creates a drainage system called French drains. The rocks are used to allow for greater drawing of water from the source area where the water was pooling. The water will flow into the rocks instead of being absorbed into the surrounding soil.
