Yuen Long Effluent Polishing Plant
Yuen Long Effluent Polishing Plant (YLEPP) is one of Drainage Services Department’s iconic projects that will adopt the most advanced sewage treatment technologies and features green design and community provisions. Portion of the plant will be transformed into public co-use area. These will serve as a medium, educating and promoting the public on sustainability. Treated sewage effluent shall be reused to reduce water consumption within the site. The biogas from treatment process are harvested to act as fuel for the combined heat and power system. Large areas of photovoltaic panels are installed on the building roof to maximize the use of limited land in YLEPP. Together with new community co-use provisions, reuse of effluent and renewable energy systems, YLEPP aims to recreate a public image on sewage treatment plants and seamlessly implement it into a local neighbourhood environment.
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.
