About the water and electricity problems
KESC is not under the city government or MQM
and
the MQM's city government provided water pipeline to the islands of karachi (sualeabad, shamspir, manora etc ) where there was no supply of water and tankers were being used
city government supplied water to liyari (which was not their vote bank its PPP's area) the water and sewerage pipelines were changed
and there are many examples
and after PPP's government was formed the mayor mustufa kamal was removed from the chairman of water board by the federal government
so now if there is any problem in the water supply or sewerage system the city government or MQM should not be blamed you should ask the federal government and what is PPP's government doing about the issues regarding water board
