Sir: Mismanagement on the part of civic authorities in collecting and disposing off garbage is making life miserable for Raiwind city residents. For some unexplained reasons, the municipal officials have not been collecting garbage that resulting in large heaps accumulating on the streets. There is an unbearable stench in many localities, and gated neighbourhoods are beginning to look like slums. The uncollected garbage also poses a health hazard, with the temperature rising and summer being upon us with all its glory. As the holy month of Ramazan is also about to begin, the city officials should look into the matter and resolve it. HAMAILA SHAH Karachi
