The water situation all over our country is looking very grim and we are facing a certain crisis should the onset of rains be delayed. Numerous campaigns even during Holi highlighted the need for having a dry and waterless festival of colours. Housing societies are earnestly practicing water conservation and many places in the suburbs are rationing water supply. Suresh Solapurkar, 65, and his nephew Sudhir Kengale, 45, from Kothrud in Pune have been working on a solution since 2014 to reduce water consumption. Their work has resulted in a device which will directly control water flow from the source – the tap in your house!
The water flow regulator that Solapurkar and Kengale, who are engineers, have devised works on the principle of gravity’s effect on the flow of water. The Golden Sparrow reports that the duo have been studying and recording the speed of flowing water and discovered,
The flow of water on the top floor of a building is the lowest, as the speed of water increases with the force of gravity. The speed and wastage of water are directly proportional, and as the speed increases, wastage escalates.”
For example, in a seven-storey building, according to their study, the top floor receives 12 litres per minute, the sixth floor 15 litres per minute, fifth floor 18 litres per minute, while the first floor gets 30 litres per minute, with a total usage of 147 litres per minute. With the water flow regulator, there is a significant decrease with all floors receiving an equal six litres per minute and reduced consumption to 42 litres per minute.
In addition to a significant reduction in water consumption and wastage, the regulator which costs Rs. 300, also reduces water tax, ensures equal distribution of water on all floors, reduces electricity bills of water pumps and boilers, and reduces load on water treatment plants. Quite a few societies have installed the regulator which can be done so either in front of or behind the tap, and have reported good experiences. Amol Vaidya, 54, former chairman of the Pride Regency Society, said,
We installed the water flow regulator, and now instead of 30 tankers that we needed earlier, we need only seven tankers a month.”
The inventors as well as those who have had good experiences with the regulator are now concerned with increasing awareness about the device which is touted to be a blessing in face of a growing water crisis.
