As time passed the way of storing the water too changed and there were only two options left- to store water in containers or to store them in heavy metal tanks or loft tanks. Earlier metal tank was considered to be very unhygienic because it had a corrosive nature. The corrosive nature is always detrimental to the water and dangerous for the health too. The RCC tanks were considered to be good, as they were very heavy in nature and were also very breakable. Due to this problem there used to be a lot of leaks and cracks which used to appear from them. With the invention of plastic tanks, all these problems were solved and storing of the water became easier.
Earlier apart from the growing demand of the fiberglass tanks, the plastic tanks had no other replacement. It used to be lightweight and also came with a durable quality. They were easily installed without any problems and could be connected easily to the water pipe.
