Drainage solutions refer to various methods and systems designed to manage excess water in an area. These solutions help prevent flooding, soil erosion, and waterlogging by directing water away from buildings, roads, and agricultural land. Common types include surface drainage, subsurface drainage, and stormwater management systems. Effective drainage solutions often involve the use of materials like drainage pipes, gravel, and retention basins. Properly designed drainage systems can enhance land usability, protect infrastructure, and improve water quality by filtering pollutants before they reach natural water bodies.
