What is a clearwell used for in water treatment?

A clearwell is primarily utilized as a storage vessel for treated potable water. After the water is treated through various processes to remove contaminants and impurities, it is stored in the clearwell before being distributed to consumers. This allows for a reliable supply of safe drinking water and provides the opportunity for additional contact time with disinfectants to ensure the water remains free of harmful pathogens.

While features such as filtration and chemical storage play critical roles in water treatment facilities, they do not define the function of a clearwell. A clearwell is not used as a filtration device or a site for storing chemicals; instead, it specifically relates to the safe holding of water that has already undergone treatment. Similarly, while water testing is a crucial part of the overall water treatment process, it does not take place within a clearwell. Therefore, understanding the purpose of a clearwell as a storage unit for treated water is essential for effective water treatment plant operations and management.
