Therefore we were constantly reminded never to pollute such water sources where the Lu resides. Such traditional concepts directly help maintain water purity by avoiding contamination. This fear based tactic has helped maintain the cleanliness of springs and reduced chances of water borne diseases in the village and nearby areas. In the past, people did not understand worms, bacteria, protozoa, and viruses as sources of waterborne diseases nor did they have any such sophisticated medications. However, they did learn that polluted water can cause many illnesses such as diarrhea and dysentery. The concept of water spirits therefore played an effective role in preventing both water pollution and diseases. This ensures water capture from clouds and rain and release of this water into the ground using the vegetation as a filter. Forest cover near water sources is believed to make the Lu happy. Apart from protecting the water springs, the villagers also started taking care of the jungle through various afforestation programs around it to strengthen the springs in the hills which had been depleted. Doing so increases the moisture in the soil which in turn increases the output of the springs. This practice is not only beneficial for improving the quality but also the flow of water and maintaining greenery.
