Happy Valley, located in the Wan Chai District of Hong Kong, is a cultural, economic and entertainment center for the city. However, it’s located on low-lying ground near the Victoria Harbor and is prone to severe flooding. Instead of more drains, the Hong Kong Drainage Services Department (DSD) chose to implement an underground storage scheme, which included a large storage tank to hold stormwater runoff and reduce downstream flooding. The DSD contracted Black & Veatch to optimize the scheme’s design. Black & Veatch’s innovative design increased the volume of the system by 25 to 30 percent, reduced excavation and material requirements and reduced the construction timetable by nearly one year, resulting in considerable cost savings and reduced environmental impacts.
*A project undertaken in Hong Kong SAR when Black & Veatch owned that business.
