Water - Every drop is precious, save it.Conservation of water remains one of the most solicited needs in today’s world. There are several public addresses, debates, television shows, lectures and workshops, hoardings creating awareness, signifying and emphasizing the necessity of water conservation. I have also been reading a lot about water scarcity and its impact on humans and animals in arid and semi-arid areas. But it is said that the true value of something is best understood when it is experienced and assessed. Staying in government quarters in the heart of Pune city with my parents since childhood, enjoying uninterrupted fairly good quality water supply by Pune Municipal Corporation (PMC) and 24 hours electricity, I never realized how privileged
we were to enjoy such facilities which are a big challenge in rural India, where villagers have to travel miles to fetch potable water. This dawned on me when we had to shift from the government-allotted quarters to our own house in Lavale village. The village is situated in Mulshi district appeared quite welcoming with greenery all around, with acres of agricultural land as farming is the main stay of the villagers. The place was out of PMC bounds and private bore-wells were the only source of potable water. Unaware of the water quality, we relied on our old ordinary water filter for a year until one fine day a salesperson approached our doorstep to demonstrate the need to have an RO/UV filter. It was then when we found that the total dissolved solids (TDS - one of the major water quality parameters) of our tap water
