Water collectors, also known as sumps (5 letters), are structures that are designed to collect and store water. They are often used to collect rainwater or groundwater, and can be found in a variety of settings, such as residential areas, agricultural fields, and industrial sites. Water collectors are typically made from concrete, plastic, or metal, and can range in size from small tanks to large reservoirs. They are an important part of water management systems, as they help to conserve and protect water resources.
