Annual dinner 2017
By Ir Simon NG

On 27 October 2017, the CV Division annual dinner was held at JW Marriott Hong Kong. More than 500 guests attended. We were delighted to have Dr David W K Chung, JP, Under Secretary for Innovation and Technology, as our guest of honour. Dr Chung addressed the guests on the development of innovations in Hong Kong which had aroused considerable interest.

We were also privileged to have the strong support of many honourable guests including Ir Thomas K C Chan, President of the HKIE, Ir Dr The Hon Lo Wai-kwok, Representative of the Engineering Functional Constituency of the Legislative Council, Past Presidents of the HKIE, Past Chairmen of the CV Division, representatives of various Divisions, Directors or Deputy Directors of government departments, officials from the Liaison Office of the Central People's Government in the HKSAR, university professors as well as representatives from various professional associations in Hong Kong, the PRC and Macau.

Ir Ian Chung, Chairman of the CV Division and Ir Simon Ng, Chairman of the Annual Dinner Organising Committee along with all the Committee Members of the CV Division proposed a toast to all guests and participants before the meal.

The theme of this year's dinner was "Inspire with innovation" which was fully demonstrated by the dinner settings, the speeches and the performance. We had arranged a truly inspiring drum jam with interactive music to uplift, empower, celebrate and connect everyone's heart and soul. The drum jam was applauded and enjoyed by the audience.

The climax of the night ended with our Committee Members playing on the stage with drum jam troupe to cheer and inspire everyone with powerful rhythms. Our members continued to enjoy chatting and drinks until midnight, at which point the master of ceremony announced the close of the dinner.

We would like to express our heartfelt gratitude to the companies and sponsors for their generous sponsorship of the event. We would also like to thank the members of the Organising Committee who made every effort to ensure that the event was not only a great success, but also lots of fun. We look forward to your continuous support of our future activities and hope that we will see you all again next year!

Technical visit to Happy Valley Underground Stormwater Storage Scheme
By Mr Vincent YIP

A one-day technical visit to Happy Valley Underground Stormwater Storage Scheme organised by the CV Division was held on 7 October 2017. 20 participants joined. This visit provided opportunities for the participants to explore one of the major flood prevention measures in the Wan Chai District. This project is also one of the pioneer construction projects that adopts the New Engineering Contract in Hong Kong.

The project includes the construction of an underground stormwater storage tank that serves as a water harvesting system. The reclaimed water can be used for on-site irrigation and toilet flushing. This water recovery system gathers and reuses water to provide an effective and sustainable method for water resources conservation in Hong Kong. The storage tank, which has a storage capacity of 60,000 cu m, is designed to provide a protection level up to a 1-in-50 year rainstorm event.

One of the iconic features of the Happy Valley storage tank is the moveable weir which is the first time being used in a flood storage tank in Hong Kong.

The moveable weir is connected to a supervisory control and data acquisition (SCADA) system. Through the control of the SCADA system, the weir opening is controlled by monitoring real time data from both the upstream and downstream water levels, and the tidal level in Victoria Harbour. The incorporation of this SCADA system helps to reduce the required size of the storage tank substantially. The system can also reduce operation costs and power consumption in the long run.

Through the visit, participants had a great experience and came to an understanding of the concepts and innovation ideas of the stormwater storage scheme. There will be more flood mitigation schemes implemented by the HKSAR Government, including temporary flood storage facilities and drainage enhancement works. Our engineers will explore further opportunities to incorporate similar automatic systems to enhance the performance of Hong Kong's infrastructure work.
