THE Liberal Party is unlikely to approve a request to the Finance Committee today for $6.8 billion to fund the sewerage programme because it says not enough information has been provided. The Government has asked for the money to be injected into a new trading fund, which will ensure all the cash goes towards sewerage services and not other programmes. But Liberal Party member Peter Wong Hong-chuen, who chairs the Legislative Council's environmental affairs panel, said they could not approve the request as it stands. He said they were given only four pages of information and were not told how negotiations with China on a critical phase of the sewerage system was progressing. He also asked why the money was being requested in one lump sum when it would be spent in parcels over several years and asked whether the Drainage Services Department was capable of managing the trading fund. Mr Wong said he did not object to the Government spending money on building sewerage works, or on households and industry being charged to cover the operating costs of the network, as is planned. ''What I'm against is they are dragooning us without adequate explanation of how the money is to be spent,'' he said. explaining the money was not needed until March but they were being pressed to approve it now. ''I just can't see us approving it.'' The United Democrats also want more information. Their spokesman on the environment, the Reverend Fung Chi-wood, said they wanted to know the full impact of the project on the environment. The sewerage system is divided in two, with the first phase collecting and treating the sewage and the second phase disposing of it by a 35-kilometre pipe in the South China Sea. Only the first phase has the go-ahead and, without the pipe, the sewage will be dumped in Victoria Harbour.
