What is one primary use of clear wells in water distribution?

Clear wells are primarily used in water distribution systems to supply stored water for peak demand. During periods of high water use, such as during hot weather or peak consumption hours, the demand for water can exceed the immediate supply capabilities of the treatment and distribution system. Clear wells act as reservoirs that allow for a buffer, ensuring there is enough water available to meet this increased demand without compromising the system's pressure or quality.

This function is crucial in maintaining a consistent water supply for consumers and can also help in managing operational efficiency within the water treatment facilities. By having this stored water readily available, utilities can better manage fluctuations in demand and ensure reliable service to their customers.

The other options describe functions that are not the primary purpose of clear wells. For instance, enhancing water flavor or reducing algae growth are not direct objectives associated with clear well usage; those goals are typically addressed through other treatment processes. Storing water for emergencies is important but not the main focus of clear wells, which are more aligned with managing day-to-day demand peaks in the water distribution network.
