Learned Amicus Curiae has also filed affidavit stating therein that the State authorities have taken positive steps for implementation of various recommendations of the Expert Committee on Water Quality Issues of Greater Shillong Water Supply Scheme but however, some time frame has to be fixed for ensuring implementation. 3. Learned Addl. AG has today produced copy of a letter No. PHE.167/2018/92, dated 02-04-2019 along with Status Report on implementation of the recommendations (e) & (f) of the Expert Committee on Water Quality Issues of Greater Shillong Water Supply Scheme, same is taken on record. Details of the recommendation have been made mention of with special focus on recommendations (e) & (f). The Engineering Department has shown complete eagerness and seriousness. Keeping in view the details as have been made mention of in the Status Report, positivity is quite apparent. According the learned Addl. AG he is under instruction to submit that minimum six months time shall be required for implementing the recommendations of the Expert Committee, particularly, recommendations (e) & (f) in its real spirit. 4. The object of the Public Interest Litigation in essence has been achieved, six months time as prayed for, for ensuring the implementation of the recommendations of the Expert Committee. State authorities concerned shall take all necessary measures for ensuring the implementation of the recommendations of the Expert Committee in its letter and spirit, preferably within a period of six months. If any extension shall be required, same will not be granted unless the authorities justify the same but we hope and trust that the authorities will not seek any further extension, because supply of safe drinking water has priority. Proceedings are accordingly closed, however, liberty to the learned Amicus Curiae to lay a motion incase the commitment for implementation of the recommendations within the time framed is not finalised. 5. Disposed of as above.
