Many buildings of Yerevan have internal garbage system (garbage pipes). It is impossible to walk by the building, go up and down the stairs, because scavenging is not done properly and there is a very unpleasant and unbearable smell throughout the building and even in the yards. All this also creates anti hygienic situation and especially in summer normal breathing becomes simply impossible.
I suggest, either to remove the garbage pipe system from the buildings or to organize their cleaning in such a way, so that there will be no odor. And just because I'm almost sure pipes cannot be properly cleaned, it will be better just to remove them. Thanks
