Salwi Steels Tanks have a long history of being used for rooftop rainwater harvesting in India. In India, state water supply departments have recognized the benefits of using these tanks for drinking water by collecting rainwater. In India, nearly every household has a tank to collect roof rainwater for drinking and domestic use.

In urban areas, Salwi Steels Tanks are ideal for rainwater storage as they can be easily installed in basements, car parks, and other hard-to-access areas that would otherwise be wasted. Additionally, Rainsavers can be fixed on the roof of Salwi Steels Tanks to collect rainwater that falls directly on the tank, a unique feature exclusive to Salwi Steels Tanks.
