The use of liquids, especially water in the factories is higher than the entire city. A single factory can use up to thousands of gallons of water in a single day. Calculate it and see how much it uses in just a month. Because of the various uses in the factory, water tanks are specially built with the ability to hold a huge quantity of water at a single time. Apart from the water tank, a factory has multiple tanks in its boundaries which contain a variety of liquids. Most of the time all of the tanks contain different types of liquids and some of them can be very dangerous ones such as acids. These liquids are stored for a purpose and procured from the respective merchants.
