Swales are garden drainage solutions that channel stormwater away from the yard through contoured depressions. Runoff water is filtered through swales by gently sinking into the soil.
In high rain density yards, a perforated pipe can be placed underneath the swale to assist with rapid water removal to an appropriate channel. You can decorate swales to resemble meadows and creek beds to boost the appeal of the yard. Plants lining the swales absorb much of the excess water, preventing the soil from being over-saturated and flooded. Swales can be lined with grasses, decorative rocks, ferns, flowers, and any variety of greenery.
Though homeowners can build small swales on their own, it’s best to consult with a professional to ensure maximum drainage capability and construction. When completed, swales offer ideal garden drainage while creating a beautiful area of greenery for the yard.
