The Drainage Services Department is fully committed to protect
the environment when delivering the drainage services. In 2009,
we met the environmental targets on conservation of energy,
chemicals and paper consumption, green procurement, waste recovery
and ecological enhancement. In addition to our continual effort
to reduce overall energy consumption, we also conducted a carbon
audit at the Shatin Sewage
Treatment Works. The audit has not only provided a measurement
of the carbon foot print for the sewage treatment processes
at the Works, but also enhanced the knowledge within the department
to extend carbon audit to other sewage treatment works in the
near future.
On sewerage services, we commissioned the advance disinfection
facility of the Harbour Area Treatment Scheme Stage 2A at Stonecutters
Island as scheduled by end 2009. Preliminary findings suggest
that the bacteriological water quality of the beaches in the
Tsuen Wan area has improved significantly. To help conserve
water and promote the concept of its reuse, we initiated a few
pilot studies to evaluate new technologies for effluent reuse
in Hong Kong, in particular on the practicality of the technologies
for the saline sewage. In response to more public concern on
odour arising from the collection and treatment of sewage in
the densely populated urban area, we presented the situation
to the LegCo members in mid 2009 and took into account their
views in refining our odour management strategy.
On flood protection, we completed the construction of the Sheung
Wan Floodwater Pumping Station in early 2009. The operation
of the pumping station not only alleviates the risk of flooding
in the low-lying Wing Lok Street and the surrounding areas in
the Sheung Wan District, but also provides a promenade for the
enjoyment of the public. This is an example of our strategy
on sustainable development, which calls for an integration of
the flood protection facilities with the community as much as
practicable. The restoration of the Yuen Long nullah is another
example of our commitment to improve the environment. Following
a feasibility study and a series of consultations with the District
Council and other stakeholders, we proceeded to the detailed
investigation stage of the project in late 2009.
This report discloses our environmental performance in 2009.
We welcome your comments as they would certainly help us improve
further on our work. Our email address is enquiry@dsd.gov.hk
