Quick Answer
A DIY seepage collection system involves digging a shallow trench and collecting water that seeps into it, often using a simple concrete or stone structure to direct the flow into a collection point.
Collecting Seepage
When building a DIY seepage collection system, it’s essential to understand that seepage typically occurs where a change in soil or rock type, or a slope, causes water to accumulate. Identify such areas and mark them for excavation. Dig a shallow trench (around 1-2 feet deep and 2-3 feet wide) in the marked area, taking care to avoid any underground water-bearing rock formations. The trench should be slightly pitched to allow water to flow into a collection point.
Directing the Flow
To direct the flow of seepage into a collection point, you can use a simple concrete or stone structure, known as a “seepage collection basin.” Build the basin by laying a 6-8 inch thick layer of compacted gravel at the bottom of the trench, followed by a 4-6 inch layer of sand. Place a perforated pipe (around 1-2 inches in diameter) in the center of the basin, ensuring it’s level and sloped slightly towards the collection point. The pipe should be buried 1-2 feet underground to prevent sediment and contaminants from entering the pipe.
Collecting and Storing Water
The collected water can be stored in a nearby container or reservoir, such as a plastic barrel or a concrete cistern. To ensure the water is safe for drinking, consider adding a simple filtration system, such as a sand filter or a ceramic filter. Regularly inspect and maintain the system to prevent clogging and contamination, and consider adding a disinfection method, like solar disinfection or boiling, to make the water safe for consumption.
