There is no information on where, when and who created the first rainwater tanks. Rainwater tanks have been used for centuries as a way to collect rain water and then use it for drinking, bathing, and cleaning.
Rainwater tanks are used to catch rainwater which falls from the sky when precipitation occurs. This is a great water saving device which can cut the cost of your water bills.

Rain water is collected through a process named Rainwater harvesting. Here rainwater that falls on the roofs are collected through pipes and ultimately stored in large tanks. These are called harvesting tanks also.
The rainwater contains minerals from the clouds, walls of rainwater tanks etc, thy just do. But water from a tap (unless bore water) Has no minerals in them and is clean and has no minerals.
Rainwater harvesting is done by collecting and storing rainwater from rooftops or other surfaces in tanks or barrels. The collected rainwater can be used for various purposes like watering plants, flushing toilets, or even for drinking after proper filtration and treatment. Gutters and downspouts are typically used to direct the rainwater into the storage containers.

Traditional rainwater harvesting is a system where rainwater is collected and stored for future use. Methods can include using roof gutters to direct rainwater into storage tanks or pits, or constructing contour trenches in the landscape to capture and retain rainfall. This practice has been used for centuries in various cultures to address water scarcity and ensure a sustainable water supply.
Large scale rainwater harvesting is when a river is dammed and the stored water is then used for irrigation, industrial and domestic uses. Small scale rainwater harvesting is when a property owner catches rainfall from a house roof and stores it in rainwater tanks for personal use, including watering, flushing toilets, washing clothes, and bathing, drinking and cooking, if required.
