Lagoons are pond-like bodies of water or basins designed to receive, hold, and treat wastewater for a predetermined period of time. If necessary, they are lined with material, such as clay or an artificial liner, to prevent leaks to the groundwater below. Lagoons can be used to store groundwater, rainwater, or any other kind of liquid that needs to be contained.
Groundwater lagoons are often used to save water that has been pumped up via wells. This can be used for irrigation, livestock, or human use.
