In 2014, Piramal Sarvajal won a first-of-its-kind tender by the Delhi Jal Board, to set up decentralized-drinking-water-solutions across various settlement colonies. Over the last four years the residents of Narela and Holambi Kalan have benefited from the affordable, access to safe drinking water. The available bore well water had Total Dissolved Solids (TDS) as high as 1300ppm, making it unfit for consumption. The situation at another settlement colony Holambi Kalan was similar with the water being delivered in tankers sourced from the stream ’Holambi Kalan Bawana Neher’ with Total Dissolved Solids (TDS) of over 800 ppm.
