Quantity wise and Clarity wise the drinking water supply has improved over the past 2-3 years. However, there is no information of the quality of the water being supplied to residential sectors. We do not know HOW DRINKABLE THE WATER really is, from the point of view of Chemical analysis.

Water quantity as supplied is quite ok. The problem is with the quality of water supplied. Quite often the water is not clear and solids in the water settle down in a bucket when kept overnight. Hence it is quite clear that the filteration process is not good enough. This needs to be corrected.
In addition the chemical composition of water must also be communicated to users, to ensure how drinkable it really is.
