A GREEN group yesterday renewed its call for scrutiny of the multi-billion dollar sewage scheme, even though the controversial lime treatment process has been scrapped.
Friends of the Earth (FoE) was at the front of the fray last year, highlighting the weaknesses of the Government's proposed $12 billion sewage plan.
Its main objection was to the 28-kilometre pipe which would dump semi-treated effluent into Chinese waters. The protests, combined with outrage and political pressure from China, forced the Government to put the scheme under review by an independent international panel.
'We are trying to keep pressure on the Government and point out what we see as the potential problem areas,' FoE spokesman Cheng Lok-ki said.
The sewage scheme is divided into stages, the most crucial being the building of a sewage treatment plant at Stonecutters Island and a pipeline for the discharge.
After the panel examined the option of treatment, it was decided that ferric chlorine would be used instead of lime. This higher level of treatment means a short outfall pipe could be used within Hong Kong waters.
