Economy of dual water supply systems
conference contribution
posted on 2018-02-12, 15:07 authored by S.L. Tang, W.L. TsangHong Kong is one of the very few coastal cities in the
world which utilize “dual water supply systems”. The dual
water supply involves two distribution systems, one fresh
water distribution system for potable use and another
seawater system for toilet flushing and fire fighting purposes.
The details of such dual water supply systems have
been given in a paper (Tang, 2000) published in the
Proceedings of the 26th WEDC Conference. The objective
of this paper is not to repeat what has been described in said
paper but to report a comparison of the economy of (1) a
single distribution system (fresh water supply only) and (2)
the dual water supply systems. In other words, the question
addressed in this paper is: would it be more economical for
Hong Kong to use a single distribution system instead of the
existing dual systems?
