A catchment basin is a type of water management system that collects and stores rainwater or stormwater runoff. This term is also known by various other synonyms including detention basin, retention pond, and stormwater management basin. In urban areas, these basins are essential for preventing flooding and ensuring a sustainable water supply. Another synonym for catchment basin is the "dry pond," which is designed to gradually release water into the surrounding soil. Similarly, a recharge basin is a type of catchment basin that is used to replenish groundwater supplies. These basins go by many names, but they all serve the same purpose of managing water resources for environmental protection and human health.
