Water shortage in the federal capital is worsening as mercury rises with sectors of the I-series hit at the most from the shortage. According to an official of the Capital Development Authority (CDA), the Authority was receiving 6-8 hundreds complaints a day regarding the insufficient supply of water most of which were coming from the I-series of sectors of the city. The Authority was trying its best to coup with the situation but the 6-hours long power outage was the major obstacle in its way, said an official of the Water Supply Directorate of CDA.
