A home-made innovation resulted in the usage of water by up to six tankers quantity each year for one household and 40 full tankers worth in the locality as the residents joined Tech Manager Prabhat Vijayan in the initiative towards conservation and cost reduction.
Hard water in taps is an issue in the outlying suburbs of Bengaluru with housing complexes depending on borewells for general use and tankers for supply of drinking water. Prabhat Vijayan installed an RO purifier and observed that the unit was discarding four litres of water for each one of the drinking water available for personal use.
Reverse osmosis or RO is a water purification system using a semi-permeable membrane to remove impurities in the water passing through, especially chlorine, dirt, salts and other contaminants like microscopic organisms.
Prabhat used a drum to store the water discarded by the RO unit. It was then utilized for mopping floors, washing cars, washroom use, watering plants and at times even for the first wash of utensils.
