Technical Site Visit to Yuen Long Effluent Polishing Plant (YLEPP), Hong Kong

Date: 13 August 2022 (Sat)

Time: 8:45 am to 12:30 pm

Location: Assembly at Long Ping MTR Station (Exit A near Wang Lok Street)

Programme Highlights

 

The existing Yuen Long Sewage Treatment Works (YLSTW), commissioned in 1984 now serves Yuen Long Town, Yuen Long Industrial Estate and Kam Tin area with treatment capacity of 70,000 m3/day at secondary sewage treatment level. To cope with the population growth and development needs, the treatment capacity of YLSTW will be upgraded to 100,000 m3 (in Stage 1) and 150,000 m3 (in Stage 2) per day and be transformed into Yuen Long Effluent Polishing Plant (YLEPP) at tertiary treatment level within the same tight footprint to meet the more stringent discharge requirements, thus minimising adverse environmental impact on the ecological setting to Deep Bay. During the upgrading works, about half of the existing sewage treatment facilities would be demolished, while the other half would be kept in operation to maintain the sewage treatment service for Yuen Long Area. The construction of Stage 1 works commenced in November 2020.

In combating climate change, design of YLEPP has taken multiple measures to minimize energy consumption and maximize energy generation, together with green building design and other sustainable features, striving towards carbon neutrality. For instance, biogas from sludge treatment process will be harvested using high-efficiency combined heat and power generator sets to support the daily operation of YLEPP.  For solar power, more than 5,300 monocrystalline-type PV panels with a total generation capacity of over 2.5 MW will be installed in YLEPP which will become one of the largest solar power generation facilities in Hong Kong upon its completion.  Moreover, YLEPP is the first wastewater treatment plant in Hong Kong adopting the advanced treatment technology of aerobic granular sludge (AGS) for biological treatment which is comparatively energy efficient with lower energy demand.

 

Through the technical visit, participants will be able to see the current civil works of the project and an understanding of the series of temporary sewage flow diversion works being undertaken in order to maintain the normal operation of the existing sewage treatment plant while the new works are carried out.
