What is the best material for a rainwater tank?

Polyethylene and polypropylene water tanks are preferred for rainwater collection because they are lightweight, durable and inexpensive. Both types of water tanks can be either opaque or translucent, Generally, an opaque, solid water tank is better because it limits the UV light exposure reducing the chances of algae growth.

How often do rainwater tanks need to be cleaned?

Since the collected water is not intended for consumption, your rainwater harvesting tank doesn’t need to be cleaned as often as a drinking water tank. However, they should still be cleaned thoroughly and disinfected at least once a year.
