A figure of watercourses that fall into Rawal Dam bring immense pollutants to the Dam as they pass through different residential countries including Barri Imam, Qaid-e-Azam University and lodging societies like Banni Gala and domestic fowl farms.
The occupants of Rawalpindi are acquiring contaminated H2O from Rawal Lake, the chief beginning of imbibing H2O for Rawalpindi. Water quality of Rawal Dam is deteriorating with each go throughing twenty-four hours as the H2O samples collected by Rawalpindi Environmental Improvement Project ( REIP ) from the lake revealed that the H2O contained high measure of phosphate and sulfate, which is unsafe for wellness.
Rawal Lake is vulnerable to H2O pollution and one major job is eutrophication, as lake H2O became unnaturally enriched with foods, doing unnatural works growing.
The Capital Development Authority ( CDA ) has decided to put in a Sewage Treatment Plant ( STP ) at Rawal Dam for handling contaminated H2O of watercourse falling into the dike to supply safe imbibing H2O to occupants of Rawalpindi.
The determination was taken in CDA board meeting presided over by the authorization s president Tariq Mehmood Khan. All the board members including Member Engineering Tahir Shahmshad, Member Finance Saeedur Rahman, Member Estate Asad Munir, Member Environment Mazhar Hussain, Member Planning and Design Tanveer Bukhari, Member disposal SM Farooqi and other senior functionaries attended the meeting.
CDA Board has besides decided that the authorization would build STPs in sectors I-14, I-15, I-16 and I-11.
1.2 JUSTIFICATION OF THE PROJECT
A multi facetted undertaking is being launched to roll up and handle the sewerage coming from assorted countries including the 1s located on west side of the railroad lines go throughing through the capital district. The topography of country comparatively slopes downwards from the Margalla Hills in the north – all towards the l-series. The sewerage from some of the sectors on east side of the railroad lines is being treated in the Sewage Treatment Plants ( STPs ) located in the Sector 1-9. Whereas the planned sector ( s ) including D-12 E-12 G-12 G-13 G-14 H-12 1-11 1-12 1-14 1-15 and 1-16 etc. and all the other country ( s ) soon non being serviced by the bing STPs have no such proviso, whatsoever, at this point. Besides, the new Sectors and the countries attributable to private lodging societies likely to be developed in hereafter would besides be expected to lend to the sewerage accretion / out flow. Owing to the alone topographic characteristics, it is non executable to transport sewerage from these countries to the bing STPs in Sector I-9.
Furthermore, the dismaying degree of pollution in the natural watercourses and surface reservoirs particularly the Rawal Lake is due to the taint – ensuing from the influx of natural sewerage from proximal home grounds. These include amongst others – the Quaid vitamin E Azam University New Diplomatic Enclave Noorpur Shahan Bhara Kau Malpur Bani Gala and all the unplanned milieus further upriver. The Quaid vitamin E Azam University and its residential settlement and the New Diplomatic Enclave are so the planned vicinities. It may every bit good be noted that, the said countries autumn within the Capital Development Authority ( CDA ) Municipal Limits. However, the staying countries though representing the Islamabad Capital Territory ( ICT ) are non administratively in Municipal bounds of the CDA. The Rawal Lake is soon the chief beginning of H2O supply to the metropolis of Rawalpindi. Hence, there is a demand to command influx of pollutant / natural sewerage into the natural H2O classs on the upstream side further adding into the lake itself. The natural sewerage / pollutants from all these vicinities are discharged into the natural H2O classs – subsequently outflow into the Rawal Lake. These include the Kurang every bit good as the 1s fluxing through Ban Imam Village and Quaid e Azam University.
In position of the above, the Capital Development Authority has decided to carry on elaborate feasibleness surveies to germinate a robust mechanism to command the threat of H2O pollution and the biological intervention thereof. The aim is to hold a set of feasible options in footings of economic systems of graduated table every bit good as conformity to the internationally acceptable environmental criterions.
