The root problem is corruption,from top to bottom in water authority of Trivandrum city.Their nexus with the contract workers and licensed plumbers are known to all.Only if a strict and impartial agency like CBI make thorough raids and searches of all these categories I have mentioned together and at the same time in a massive cleaning up operation and punishment of the guilty,can give any results.Corruption,unaccounted wealth in crores amassed by unscrupulous people of these categories etc have to be exposed and made known to the tax payers.But who will do these things?
