What is the main purpose of a distribution system reservoir?

The main purpose of a distribution system reservoir is to store water and provide a buffer for peak demands. This is essential in water distribution systems as reservoirs help balance the supply and demand of water. During times when water consumption is high, the reservoir can release stored water to ensure consistent service and pressure. Conversely, during periods of low demand, the reservoir can be replenished, ensuring there is enough water available for future needs.

Reservoirs play a crucial role in maintaining reliable water supply, especially in situations where water usage can vary widely throughout the day or season. By acting as a buffer, they help to stabilize the distribution system and prevent scenarios where demand exceeds supply, which could lead to shortages or pressure drops. This capacity to manage fluctuations in water use is integral to effective water distribution management.

Other options, such as providing water for recreational purposes, filtering and purifying water, or managing stormwater runoff, serve different functions and are handled by other systems or facilities rather than the distribution system reservoir itself.
