The Golden Rule of Water
1 Cubic Meter of volume holds exactly 1,000 Liters of water. 1 Cubic Foot holds approximately 28.31 Liters.

Freeboard Space
Never fill a tank to the very brim. Always leave 150mm to 300mm (6 to 12 inches) of "freeboard" space at the top to prevent overflow.

Per Capita Requirement
Indian standard (IS 1172) recommends 135 Liters of water per person per day. A family of 4 needs a tank of at least 540 Liters for daily use.
