Delhi Jal Board is discharging human excreta in the form of sewage waste into an open rain water drain in Inderpuri instead of discharging it into the underground sewage pipeline, which is lying blocked since the past 10 yrs. This has led to unchecked breeding of flies and mosquitoes and consequently vector borne communicable diseases. The protectors of our health and hygiene have become the destroyers of it. The stench in this open drain is simply unbearable and this is a residential colony in Central Delhi. Mohenjo Daro probably had a better sewage system. I have approached the Chief Minister, CEO Delhi Jal Board, Lt Governor and Commissioner MCD but to no avail.
