The status of environmental cleanliness is one of the indicators of development of a nation. As a nation, we have to keep our environment clean and tidy including all our places of worship and rivers. In this connection I would like to narrate the improvement of Kali Bein rivulet, the place where Gurunanak Devji is said to have received enlightenment. Over the years this rivulet has turned into weed choked drain. Recently river is clean due to the efforts of Baba Balbir Singh Seechewal in partnership with the Punjab State Government. From the discussions, I understand that he organized people?s participation in stopping the massive flow of sewage into the Bein and cleaned 160 km long polluted and choked rivulet within the last five years by deploying on an average 3000 volunteer pilgrims per day. Today one can feel the flow of fresh water in this rivulet released from the Tarkina Barrage by the government. The revival of the rivulet has recharged the water table as the hand pumps that had become dry for the past 4 decades are now pumping out water. I am sure this model can be followed by the children of B.C.M. Arya Model Sr. Secondary School and others schools in Punjab. This will definitely be an important societal mission.
