Project summary

The Salt Water Supply System for Pok Fu Lam Area is a design and construction supervision assignment (the Project) commissioned by the Water Supplies Department (WSD) of the Hong Kong Special Administrative Region, for a new salt water supply system serving the Pok Fu Lam area of Hong Kong Island. The Project was commissioned in July 2007. Upon completion of the Project, the system will supply salt water, instead of fresh water for flushing, to the Pok Fu Lam area every day and is expected to save substantial amount of fresh water a day.

• construction of Telegraph Bay Salt Water Pumping Station (TBSWPS) and the associated sea water intake culvert at Telegraph Bay seafront area;
• construction of Wah Fu Salt Water Service Reservoir (WFSWSR) near Wah Fu Estate;
• construction of Wah Fu Salt Water Pumping Station (WFSWPS) near Wah Fu Estate;
• construction of Pok Fu Lam Salt Water Service Reservoir (PFLSWSR) on the hill behind Pok Fu Lam Village;
• laying of the associated salt water mains; and
• all the associated civil, structural, geotechnical, electrical and mechanical works including site formation, rock excavation, landscaping, permanent and temporary accesses which are necessary for the completion of the works as listed above.

The Historic Environment

Although there are no archaeological remains within the development area, four masonry bridges located at the main access road to the Pok Fu Lam site were identified. Soon after the commencement of the Project, these bridges were announced as Declared Monuments and the Project was suspended to carry out protection measures to the bridges. Temporary bridge mitigation works were put in place to minimise damage, including adding structural support by steel and also controlling the traffic of heavy vehicle trucks during construction. The protection works to the bridges was performed by professional structural engineer and monitored by historian professional from the statutory organisation.
