Flood protection plan awarded

The Drainage Services Department’s Stormwater Interception & Storage Schemes for Hong Kong Urban Areas have won the 12th Tien-Yow Jeme Civil Engineering Prize in the Municipal Engineering Category.

Speaking at the prize presentation ceremony in Beijing today, Deputy Director of Drainage Services Mak Ka-wai said it is encouraging for the department’s flood prevention projects to again be recognised by professional bodies after winning of the International Water Association Global Project Innovation Award in September.

The department formulated an urban flood protection strategy with the novel concepts of stormwater interception and storage.

For stormwater interception, the department constructed drainage tunnels in Hong Kong west, Lai Chi Kok and Tsuen Wan to intercept stormwater from uphill.

The stormwater bypasses downstream urban areas and is discharged into the sea directly, significantly alleviating the flooding risk.

Under the stormwater storage schemes, the department constructed underground stormwater storage tanks in Tai Hang Tung and Sheung Wan to store stormwater temporarily during heavy rainstorms for discharge after the peak flow, thereby resolving the flooding problems in low-lying urban areas.
