HydroGrameen, is a combination of Bengali and Indian words for "jhol" or "pani " (both Sanskrit words), for water and "gau" or "garam" for village ). When work was in progress, it was known as Bengal Basin Working Model. Both Berkeley and Harvard professors also contributed in the development of the Bengal Basin model in late 1990s and early 2006. The Bengal Basin model was renamed "HydroGrameen" to reflect the Indo-Bangla culture and tradition where the idea was born and the work started.
The HydroGrameen Technology involves injecting fresh, clean water to replenish depleted aquifers in a safe way to protect the world's most invaluable resource, water. This technology can be used to build a new watershed as well as to protect the existing one and make them self-sustaining by installing eco-housing based on eco-economics. The economics must be based on ecology, the environmental and improvement of quality of life. The drinking water research began in Ancient India when many civilizations at their dawn. This technology has taken shape after 35 years of work in Bengal Basin, Great Britain and California. Finally, it was in Berkeley, California that the technology has come to fruition. HydroGrameen has become possible with the availability of advance technology that has been developed by US and Europe and tested repeatedly and proven to be safe.
