What is the primary purpose of a storage tank in a water distribution system?

The primary purpose of a storage tank in a water distribution system is to provide a reserve of water for peak demand and emergency situations. These tanks play a critical role in ensuring that there is always a sufficient supply of water available, particularly during times when water usage is at its highest or during unforeseen circumstances such as system failures or natural disasters.

By maintaining a reserve, storage tanks help to stabilize water pressure within the distribution system, making it possible to meet varying demands throughout the day. For example, during peak usage hours, such as early morning or evening when residents are most likely to use water, the stored water can be released to supplement supply. Additionally, in emergency scenarios, such as a broken water main or a fire that necessitates an abrupt increase in water flow, these tanks provide immediate access to the necessary volume of water.

While enhancing flavor, reducing evaporation, and purifying water are important aspects of overall water management, they do not align with the fundamental role that storage tanks serve in maintaining system reliability and consistent supply under varying conditions.
