The National Water Supply and Drainage Board (NWSDB) is ready for a possible dispute with the Colombo Municipal Council (CMC) and the Western Provincial Council as both institutions are opposed to the taking over of Colombo's sewerage system by the former. In a surprise move yesterday the CMC decided to oppose the handing over of the sewerage system to NWSDB which comes under the Ministry of Water Management. This was a sudden and surprising decision as the Council had passed a motion to hand over the sewerage system to the Water Board during the sessions on February 12. However a fresh proposal to revise the earlier decision was unanimously passed at the sessions yesterday. The motion which was presented yesterday was signed by several councillors including JVP Member, Hemantha Kumara, DUA Councillor, Roy Bogahawatte and F. M. Sharafdeen. Mr. Bogahawatte who moved the motion said the NWSDB Chairman had taken this decision on his own as the subject Minister has not made such a request. Meanwhile the main opposition UNP was to move a motion to oppose the NWSDB move to takeover the sewerage system at the Western Provincial Council sessions today. The motion was to be moved by the UNP Provincial Councillor, C. Y. P. Ram. Mr. Ram told Daily Mirror the takeover of the sewerage system by the NWSDB would pave the way to impose a sewerage levy from the city dwellers. He said this would be charged as a percentage of the total amount shown in the water bill. The party was to request the Western Province Chief Minister, Reginold Cooray to take steps to prevent this act taking into consideration the difficulties faced by the people due to the sky rocketing cost of living. Mr. Ram said some UPFA councillors have pledged their support and were expected to vote for it. He said he would discuss with the JVP too and was confident that the party would also support him. According to Mr. Ram the Attorney General had also stated the taking over of the sewerage system was illegal as there was no move to seek approval of Parliament which was compulsory for such a take over.
