Any standing water can get areas that mold grows, along with bacteria. If not used for drinking, you could add a CAP (using the lid) of bleach for every 10 gallons. The bleach will help prevent organisms from growing. You should also empty the tank every few months and scrub it with dish detergent and water. Cleaning mold with bleach does not kill mold; it only turns green or black mold to a bleached white color but the mold remains unless it is scrubbed out.

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.
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.
Water harvesting is a method of collecting rainwater in storage tanks or pits which are dug underground; the purpose is to store the water for future use in irrigation or to increase the water table.
