Bhungroo

Product Description

Bhungroo is a product developed by Naireeta services to address waterlogging and draught problems in farmers fields. Bhungroo is a term in colloquial Gujarati meaning a straw or hollow pipe. During monsoon, Bhungroo is used to harvest the excess water available during storms and waterlogging.
It is an efficient rain water conservation technology by use of pipes of 10 to 15 cm in diameter. During monsoon this technology injects, filters and stores the excess amount of water in a subsurface zone and then it can be made available for use during lean periods or draught. It requires a surface space of only 1 square meter and takes care of 1 to 4 million liters of water each year.
