What is the main purpose of clear wells in a water distribution system?

The primary function of clear wells in a water distribution system is to store treated water before it is distributed to consumers. These storage tanks act as reservoirs that ensure an adequate supply of water during peak demand periods. By providing a buffer between the water treatment process and the distribution system, clear wells help maintain pressure and flow in the system, allowing for consistent delivery to users.

By having a dedicated storage facility, water systems can better manage fluctuations in demand, such as during hot weather or special events when usage spikes. This design aids in ensuring that customers receive a reliable water supply while also reducing the strain on treatment facilities, allowing them to operate efficiently.

While other options touch on important aspects of water quality and safety, they do not accurately reflect the specific role of clear wells. For instance, filtration and chemical treatment occur at different stages of water treatment and are not the primary responsibilities of clear wells. Monitoring contaminants is also critical for ensuring water safety, yet it is not the function of clear wells, whose focus is firmly on storage and supply.
