ISLAMABAD The Capital Development Authority (CDA) is taking concrete measures for the restoration and preservation of natural streams and nallahs across the federal capital with a view to reviving the capitals natural beauty. This was stated by Chairman CDA Imtiaz Inayat Elahi while addressing a seminar titled Save streams, save the life on earth organised by the Rotary Club Islamabad here on Sunday. The CDA Chairman said that a survey for cleaning of nallahs had been completed recently and implementation mechanism was being streamlined for cleaning of the natural steams. He said that Islamabad was the only city of the country, which had unique aspect of environment as a dominating factor, however, the rapid increase in population, massive development and inadequate management of the ecosystem has damaged the green posture of the city. He said that now they have resized their priorities and conservation of environment has been taken as the primary objective of the future development. He said, Our environmental conservation efforts are bearing fruits and Islamabad has been designated as the green city. He said that massive tree plantation campaigns on part of civic body had been a part of the environmental protection effort. An innovative concept of Rain Water Harvesting had been initiated under which more then 20 such projects had been completed which has helped recharge ground water table by 15 to 20 feet. Imtiaz Inayat Elahi said that CDA had constituted a task force in collaboration with Rotary Club to identify the causes and factors, which have contaminated the streams in Islamabad. The CDA chief also apprised the participants that the lack of awareness on the part of the residents was also multiplying the factor as the debris and solid waste was being illegally dumped into these natural steams and Nallahs as well as the encroachment by the adjoining residents was also a major problem which had related the flow of the steams. Imtiaz Inayat Elahi said CDA had taken some primary measures to rectify the problem. In this connection the broken sewage line in sector G-6 and Diplomatic Enclave have been repaired, illegal sewage lines in Bari Imam had been unplugged and residents were now constructing the septic tanks for their sewage waste. The Chairman CDA called upon the public and private sector to work jointly for sustainable solution to this problem. He said that key to success in this regard lies in education and awareness of the general public to pave the way for restoration of natural steams of Islamabad.
