How Modular Rainwater Harvesting System differ from Traditional Rainwater Harvesting?

Rainwater harvesting is not a new terminology for Indians. For over 4,000 years, people have been practising rainwater harvesting since the ancient administration suggested rainwater for fundamental needs. They have learned that source water is not the only source to serve their water requirements. However, storing the rainwater in a storage tank is a modern-day practice. So, shifting our attention to a modular rainwater harvesting system is pretty obvious, especially when we are facing water scarcity.
