Quick Answer
To ensure proper drainage in a buried barrel, dig a slight incline and a drainage trench to direct water away from the barrel, then cover the trench with gravel. Add a filter fabric or geotextile to prevent soil particles from clogging the drainage. Monitor and maintain the barrel's surroundings to prevent water accumulation.
Digging the Drainage Trench
When burying your barrel, dig a slight incline (about 1-2% gradient) to allow water to flow away from the structure. This incline should extend 2-3 feet beyond the barrel’s width on all sides. Next, dig a shallow drainage trench (about 6-8 inches deep and 12-18 inches wide) around the barrel, following the incline’s direction. This trench will direct water away from the barrel and prevent it from accumulating around the structure.
Installing a Drainage System
Line the drainage trench with a filter fabric or geotextile to prevent soil particles from entering the trench and clogging the drainage. This will ensure that water can flow freely through the trench and away from the barrel. You can also add a perforated pipe or a French drain to improve the drainage system’s efficiency. Keep in mind that the pipe should slope at a rate of about 1-2% to allow for gravity-driven flow.
Maintaining the Barrel’s Surroundings
Regularly inspect the barrel’s surroundings to ensure that the drainage system is functioning properly. Check for any signs of water accumulation or erosion around the barrel and trench. If you notice any issues, address them promptly by adjusting the drain’s slope or adding more gravel to improve drainage. By maintaining the barrel’s surroundings, you can help prevent water damage and ensure the longevity of your root cellar alternative.
