How do you divert water runoff?

  1. BUILD A BERM, a small hill covered with grass or otherplantsthat will divert runoff around what you want to protect.
  2. ROUTE THE WATER INTO A DRY WELL.
  3. GRADE BROAD SURFACES to direct runoff away from houses,sheds,barns, and patios.
  4. INTERCEPT THE WATER by using a swale, a shallow ditchwithgently sloping sides.

How far apart should Swales be?

Of course it depends . . . but a general rule is thatyouwant to space swales the tree height apart. So ifyourplan to plant trees that will be 100 feet in the air, then youwantyour swales 100 feet apart. If you are plantingtreesthat will mature to 15 feet tall, then dig swales 15feetapart.

How do drainage swales work?

Swales follow the contours around the base ofanatural or created slope, redirecting storm water andfilteringrunoff as it sinks into the soil, instead of keeping it inoneplace, like a rain garden. Plants suck up the water alongaswale's gently sloping banks and sometimes down thecenterof the channel.
