Project Background

The existing Yuen Long Sewage Treatment Works (YLSTW), was commissioned in 1984 with a design capacity of 70,000 m³/day provides secondary level treatment to sewage catchment from Yuen Long area such as Wang Chau, Yuen Long Industrial Estate, the Yuen Long Town and Kam Tin.  Due to future needs, the existing YLSTW will be upgraded to Yuen Long Effluent Polishing Plant (YLEPP) with tertiary treatment level and increased capacity from 70,000m³/day to 150,000m³/day in 2 stages.  The discharge standard will be enhanced from the implementation of the project.

YLEPP and Neighborhood

During the planning stage, YLEPP had been highly involved in public engagement in gathering support from stakeholders, such as rural committee, district council and green groups.  Views from stakeholders on odour, ecological and environmental aspects, etc. are received and the design options have been reviewed to minimize the potential environmental impacts through various mitigation measures.  For example, rooftop bird hide in lieu of floating bridge on Shan Pui River was adopted to avoid ecological impacts but maintain its education purpose.  The process of public engagement had successfully balances the stakeholder’s concerns to solicit consensus on this project.

YLEPP and BEAM Plus

YLEPP is located near wetlands and rivers, it is accessible to green space and blue assets.  Together with sensibly planned spaces based on local standards and guidelines, YLEPP provided high quality recreational spaces for the public.  Renewable energy systems, like combined heat and power generation and photovoltaic panels are adopted as energy sources to the site.  With the above major strategies, YLEPP reached the BEAM Plus Platinum rating.
