Water tanks serve several crucial functions, primarily enabling water storage and ensuring a steady water supply.

The capacity of a water tank can vary widely, ranging from small containers that hold a few hundred liters to large tanks capable of storing thousands of gallons. Some water tanks are equipped with features to maintain water quality, such as filtration systems to remove impurities or prevent stagnation.
Water tanks are typically equipped with inlet and outlet valves, allowing water to flow in and out as required. They may also have a gauge or level indicator to monitor the water level and prevent overflow or depletion. Regular maintenance and cleaning of water tanks are necessary to ensure the stored water remains safe for various applications.
