Sludge dewatering upgrading works contract signed

The Drainage Services Department has started works to upgrade the sewage sludge dewatering facilities of four major secondary sewage treatment plants in the New Territories.

A $109.8 million contract for upgrading the facilities at sewage treatment plants in Tai Po, Shek Wu Hui, Yuen Long and Sai Kung was signed today (Tuesday) by the department's Assistant Director (Electrical and Mechanical), Mr Ivan D'Souza, and a representative of the contractor, Ryoden Engineering Company Limited.

Speaking after signing the contract, Mr D'Souza said upgrading of the facilities was necessary in order to achieve the latest sludge landfill disposal requirement by the Environmental Protection Department.

"It is required that by mid-1997, all sludge disposed of at the three strategic landfills should have a dry solids content of 30 per cent by weight.

"In order to achieve this new requirement, it is necessary to install new sludge dewatering facilities which will be able to produce drier sludge.

"Moreover, with the installation of new sludge dewatering facilities, the volume of the dewatered sludge to be disposed of to the landfills will be drastically reduced. Waste water production by the disposing sludge in the landfills will also be lowered," he explained.

Mr D'Souza pointed out that the existing sludge dewatering facilities at sewage treatment plants in Tai Po, Shek Wu Hui and Yuen Long were commissioned in mid- 1980s.

"They will come near the end of their economic life by 1997, and therefore replacement of the facilities is necessary," he said.
