1.1.1
The existing Yuen Long Sewage Treatment Works (YLSTW) is a
secondary sewage treatment works, located at Yuen Long Industrial Estate serves
Yuen Long Town, Yuen Long Industrial Estate and Kam Tin areas with a design
capacity of 70,000 m³ per day. Based on the latest planning data, the volume of
sewage generation from the YLSTW catchment is estimated to increase to 150,000
m³ per day after 20 years. In addition, since YLSTW has been operating for over
30 years and most of its facilities are of out-dated design and reaching the
end of their design life, the environmental facilities of the plant will also
be upgraded and hence improving the adjacent environment through upgrading the
YLSTW to Yuen Long Effluent Polishing Plant (YLEPP). The Location of Proposed
Yuen Long Effluent Polishing Plant is given in Figure 1.
1.1.2
YLSTW will be reconstructed in two stages to increase its capacity
to 150,000 m³ per day. The proposed works, as Stage 1 of the project, will
firstly increase the treatment capacity to 100,000 m³ per day. In the course of
Stage 1 construction, about half of the existing facilities of YLSTW would be
demolished, while the other half would be kept in operation to maintain the
sewage treatment service for Yuen Long area.
1.1.3
The Project is a designated project under Schedule 2 of the
Environmental Impact Assessment Ordinance (EIAO) (Cap. 499) for which
Environmental Impact Assessment (EIA) report and Environmental Monitoring and
Audit (EM&A) Manual was approved by EPD (Register No.: AEIAR-220/2019) on
25 April 2019. The Environmental Permit (EP) (EP No. EP-565/2019) to construct
and operate was issued by EPD on 26 April 2019.
