The answer to 'DIY drainage system' is that you can install a basic drainage system yourself to help manage water runoff and prevent flooding around your home. This involves digging trenches, laying drainage pipes, and creating a slope to direct water away from your foundation.
Start by identifying problem areas where water collects, then plan out the drainage system. Dig trenches 6-12 inches deep and lay perforated drainage pipes, covering them with gravel or crushed stone. Create a gentle slope of 1-2% to guide water to a suitable outlet like a dry well or municipal storm drain. Be sure to call 811 to locate underground utilities before digging. For more extensive drainage needs or if you encounter issues, it's best to consult a professional landscaper.
