What is the function of storage tanks in a water distribution system?

The function of storage tanks in a water distribution system is primarily to provide a reserve of water for peak consumption and emergencies. These tanks ensure that there is enough water available during times of high demand, such as peak usage hours when many customers draw water simultaneously. Additionally, they play a crucial role in providing an emergency supply during unforeseen circumstances, such as power outages, pump failures, or natural disasters. By maintaining an adequate water supply in storage tanks, water distribution systems can manage variations in demand effectively and maintain consistent water pressure, ensuring reliable service to consumers.

Other options do not accurately reflect the role of storage tanks. Enhancing water flavors and storing contaminants are not functions of storage tanks, while serving as a backup for regulatory compliance is a much narrower aspect that doesn’t capture the essential purpose of storage tanks in managing supply and demand. Thus, the correct answer underscores the fundamental role of storage tanks in operational readiness and user satisfaction in water distribution systems.
