What is the required minimum daily average supply from combined elevated and ground storage tanks?

The required minimum daily average supply from combined elevated and ground storage tanks should provide sufficient water to meet demand even during peak usage times, equipment failures, or unexpected supply interruptions. Selecting a minimum of half a day represents a balance between maintaining adequate water pressure for customers and ensuring that there's enough water available for firefighting, emergency situations, and other essential services.

This half-day supply offers a safety net for water distribution systems, ensuring that users will not experience shortages during critical periods. Moreover, by maintaining at least this level of storage, operators can effectively manage their water supply based on consumption patterns and are better equipped to respond to fluctuations in demand without risking low water levels in storage tanks.

In contrast, shorter supply durations like four hours or a quarter of a day may not provide the necessary buffer for unexpected demand spikes or system failures, leaving the community at risk for low pressure or outages. Having a supply for an entire day would be excessive for everyday operational needs, as it could result in increased costs and challenges in managing larger volumes of water. Therefore, a minimum of half a day strikes an appropriate compromise, ensuring reliability while optimizing the use of storage capacity.
