Why do you need to install overhead tanks in the uppr part'?

Overhead tanks are installed in the upper part of a building to ensure adequate water pressure and distribution throughout the structure. By utilizing gravity, these tanks allow water to flow naturally to lower levels, reducing the need for mechanical pumps and saving energy. Additionally, overhead tanks provide a reliable water supply during peak usage times and can serve as a backup source during outages. This setup helps in efficient water management and accessibility.
