A sump is a pit or reservoir designed to collect and hold liquids, often water or wastewater. It is commonly used in basements or low-lying areas to prevent flooding by gathering excess water. Sumps are typically equipped with a pump, known as a sump pump, which removes the collected water and directs it away from the building. Sumps can also be found in various industrial applications, where they help manage liquid waste or runoff. In these settings, they play a crucial role in maintaining safety and environmental standards by ensuring that hazardous liquids are properly contained and disposed of.
