DGs EPA Punjab and federal government informed the court that besides issuing notices they have filed cases against the violators in the Environment Tribunal, Punjab.

Rawal Lake is an important artificial fresh water reservoir that provides 23 million gallons clean drinking water to inhabitants of Rawalpindi city and cantonment areas. There are four major streams and 43 small streams contributing to its storage. The poultry farms and the human settlements, especially huge amount of raw sewage coming from urban settlements, including sewage from Quaid-i-Azam University, Bari Imam, Mall-pur, Noor Pur Shahan, Bani Gala, Bhara Kahu, Diplomatic Enclave and Murree pollutes the lake water. The increased human activities in the catchments area have deteriorated the raw water quality of the lake beyond acceptable limits. Due to that not only the filtration cost of the raw water has increased manifolds but also it is adversely impacting health of Rawalpindi city and cantonment residents. The WASA has demanded ban on the construction activities in the Rawal Lake catchments area comprising Zone 3 and 4. The water treatment plant installed earlier to treat raw water of Rawal Lake is unable to filter the pollution, said the managing director WASA. He said that twice they have upgraded the treatment plant but now they dont have capacity to further upgrade it. The court has adjourned the case till 1st October.
