A dry well is simply a large hole filled with gravel or other aggregate that picks up the excess water and holds it up as it penetrates the soil. You can increase the capacity of a dry well by burying barrels of special dry wells. These plastic containers collect the water and hold it as it flows through the holes on the sides and bottom. Containers should be surrounded by gravel or other porous material to allow drainage. You can stack these dry plastic wells or place them side by side. In general, a dry well should be large enough to collect the first 10 or 15 minutes of heavy rain. Websites like ndspro.com provide tips and calculators to help you determine the size of your dry well.
