A TOP trailer firm is playing its part in helping to clean up one of the world’s most famous harbours.

Since 2001 work has been in progress on a sewage treatment scheme in Hong Kong’s Victoria Harbour.

The first phase, costing almost £1bn has been completed and now the second phase is under way.

The main contractors are Leighton Asia Limited, Australia’s largest civil engineering company.

They have turned to Ifor Williams Trailers, who have a factory on Deeside, for assistance with the $410m contract.

Eight of the company’s P6e trailers are currently on their way to Hong Kong, where they will be used to deliver equipment to 21kms of tunnels and also in any emergency rescues on site.

With a population of five million people living around the harbour, sewage disposal has long been a major problem there.

The project is part of the Hong Kong Government’s Harbour Area Treatment Scheme (HATS).

Until 2001 raw sewage was dumped straight into the harbour, giving it a particularly grim appearance and a rather musky smell.

The aim is to create a world class sewage collection and treatment infrastructure which will restore Hong Kong’s harbour to a more natural and healthier condition.

The first phase of the project has led to 75% of the sewage discharged into the harbour now being treated. The remaining 25% will be treated when the second phase is completed.

Daniel Joyce, a sales co-coordinator with Ifor Williams Trailers, said: “In the UK we are used to the idea of importing goods from places like Hong Kong so it’s gratifying that we are sending our market-leading trailers in the opposite direction.”
