Hong Kong Expands Use of Cavern Service Reservoirs to Free Up Land
Housing service reservoirs in caverns is a technically viable alternative that can increase land supply.
The Water Supplies Department (WSD) of the Government of the Hong Kong
Special Administrative Region is considering relocating the Diamond Hill
Fresh Water and Salt Water Service Reservoirs (DHSRs) to caverns.
WSD has appointed Black & Veatch to investigate, design and supervise
the construction of the caverns and the new DHSRs.
“Enhancing land resources is critical to Hong Kong’s success. Housing
service reservoirs in caverns is a technically viable alternative that
can increase land supply. By collaborating with WSD, we are able to
address the key requirements of delivering a world-class facility,” said
Andy Kwok, Managing Director, Black & Veatch Hong Kong.
The main objective for the project is to release land for other
beneficial uses while still providing a quality water supply to the
local areas.
A new fresh water service reservoir, a new salt water service reservoir
and associated pumping stations will be constructed within the caverns
to replace the existing installations.
Black & Veatch will be involved in designing tunnels, caverns and
associated works for the new DHSRs; optimizing the water supply systems
of the proposed service reservoirs; and decommissioning the existing
DHSRs and pumping station.
Across the world, Black & Veatch has demonstrated the ability to
successfully design and manage the construction of reservoirs and other
water infrastructure. The company offers integrated and collaborative
solutions, exemplified in Hong Kong by the construction of the
award-winning Western
Salt Water Service Reservoirs.
Editor’s Notes:
-
Black & Veatch was engaged by WSD as the consultant for the
“Relocation of Diamond Hill Fresh Water and Salt Water Service
Reservoirs to Caverns - Feasibility Study.” -
Black & Veatch pioneered the design and construction of the
re-provisioning of the Western Salt Water Service Reservoirs in a rock
cavern, which released land for the development of the school campus
at the University of Hong Kong. With this approach, slope cutting of
300,000m3 and a significant amount of tree felling were
avoided. This approach reduced construction costs and time. The
project won the Hong Kong General Chamber of Commerce’s Innovative
Award and 2010 International Water Association (IWA) Project
Innovation Awards (East Asia Regional Awards) in the Design Category. -
Other cavern/tunnel projects Black & Veatch worked on include the
Relocation of Sai Kung Sewage Treatment Works to Caverns and
Inter-Reservoirs Transfer Scheme – Water Tunnel between Kowloon
Byewash Reservoir and Lower Shing Mun Reservoir for the Drainage
Services Department of the Hong Kong Government, and Long-Term
Strategy for Cavern Development in Hong Kong for the Civil Engineering
and Development Department (CEDD). CEDD is a department of the Hong
Kong Government that reports to the Development Bureau.
