At the time when people started moving in Noida some 25 years back, they were not aware that they would also have to live with water problems. The hardness of water is one of the issues which are troubling residents of several sectors across Noida for a long time now. The TDS level in water is found to be 1500 and in some sectors it is more than 1800 and 2200. However, the normal TDS in water should be 500, according to the World Health Organisation.

"The TDS levels in water vary across all sectors in Noida. The TDS level in Sector 93 is 1800 and in Sector 40 it is about 1200 and in sectors 40 and 44, it is nearly 1000-1200," said Pintu Kumar Pandey, zonal head water treatment, Noida Authority.  
As the TDS levels are high, quantity of undesirable minerals like calcium and magnesium are also high. This leads to several issues like corrosion of electric appliances, pipes and taps. Also, usage of hard water leads to rough skin, damaged fabric and sweeping and mopping of floors also becomes tough as detergents don't lather well. Residents are a worried lot as they have to bear the brunt.

"Although we use purified water for drinking purposes, but we cannot avoid contact of this impure water. Due to this, we frequently fall sick. We cannot use RO for each and every purpose like bathing and cleaning utensils," said Anil Singh, resident of Sector 93.

Residents residing in Sector 55 share the same sentiments. "When I came to Noida, my skin was good but now my skin has developed rough patches and now I have to deal with hairfall also," complained Puja Srivastav, resident of Sector 55. Besides, the hard water also leads to harmful diseases like kidney stone and sometimes even cancer.

“Every year, there's a spurt in cases of water-borne diseases in summers where as the high TDS drinking water is very harmful for the health. It can cause hardening of the skin problems, arteries blockage, kidney stones and gall stones “said Dr Manisha Shah, a general physician from Lal Bahadur hospital. "We brought filters and softeners also so that we can use better quality of water but following high TDS levels, even the filters and softeners corrode within five months," said Vinod Sharma, resident of Sector 47.

Meanwhile, due to variations in TDS levels across various sectors, the Noida Authority has divided the region into 56 water supply network. They are mixing Ganga water in ratios such that people can use soft water which also makes it fit for drinking. As per the requirement, 25-30 percent of Ganga water is mixed with the normal water to make it soft.

In the first phase, Noida Authority mixed 48 MLD Ganga water in 2005. In second phase Additional Ganga water project is under execution which shall be completed by September 2013 which will use 192 MLD Ganga water. Shama Kant Srivastava, (Project Engineer), Noida Authority said, "I know that Noida receives hard water and we believe that Ganga water should be used to dilute the current hardness of water."
