Become a memberIr Professor CHAN Pak Keung
Professor CHAN Pak Keung obtained a BSc (Eng) in Civil Engineering from HKU in 1977. He became a qualified civil engineer in 1980 after receiving three years professional training in the Public Works Department. In 1980-87, he worked as an engineer on the design of the preliminary treatment and disposal facilities on Hong Kong Island with his capacity strengthened by a government sponsored part-time MSc (Civil Engineering) Programme in HKU in 1982-85, especially its environmental engineering subjects.
In 1987-88, Ir Professor CHAN was sent by Government on an 11-month full time post-graduate International Course in Hydraulic Engineering at IHE Delft the Netherlands | Institute for Water Education, to prepare him to address Hong Kong’s worsening flooding problem in 1980’s. Upon his return to Hong Kong at the end of 1988, he was deployed as a senior engineer initially on the design of Shenzhen River Regulation and then in conducting strategic and master planning studies to address the land drainage and flood control problems in Hong Kong.
In 1998, Ir Professor CHAN rose to Chief Engineer (Drainage Projects) overseeing the design and construction of the River Training and Village Flood Pumping Schemes (Polders) in Yuen Long by in-house staff. In 2000, he was moved to Chief Engineer (Sewerage Projects) to lead the design and construction by in-house staff of the extension & upgrade of treatment works at Shatin, Tai Po, Shek Wu Hui, Sai Kung, Pillar Point & Cheung Chau as well as the gravity sewers, rising mains and pumping stations in Yuen Long and North District. In 2007, he was moved to Chief Engineer (Land Drainage) to oversee the investigation & planning of flood management facilities by commissioning consultancies.
From 2010 to 2014, Ir Professor CHAN was Assistant Director of Drainage Services, overseeing the Operation & Maintenance Branch initially and later the Sewage Services Branch. In 2014, he was awarded an Honorary Fellow by the Hong Kong Chapter of the International Association for Hydro-Environment Engineering & Research (IAHR-HK) to recognize his contributions in supporting the applications of hydraulic research in Hong Kong’s environmental and hydraulic engineering projects.
After his retirement at the end of 2014 from the civil service, Ir Professor CHAN has been active in water education, contributing to civil and environmental engineering undergraduates and postgraduates’ programmes at HKU and PolyU. From 2015 to 2018, he was Professor of Practice (Infrastructure), PolyU and has been Adjunct Professor of HKU since 2015. He has also taught practising engineers and environmental scientists CPD courses organised by HKPC, Advanced Technovation, LNS and RED.
