Water containment refers to the methods and structures used to hold or store water for various purposes. This can include reservoirs, tanks, and ponds designed to collect and manage water for drinking, irrigation, or industrial use. Effective water containment helps prevent flooding and ensures a reliable water supply. In addition to storage, water containment systems can also play a role in environmental protection. For example, wetlands can naturally filter pollutants, while dams can control river flow and maintain ecosystems. Proper management of these systems is essential for sustainable water use and conservation.
