Content - Summary
The Institute for Sustainable Futures (ISF), from the University of
Technology Sydney, in collaboration with Can Tho University (CTU)
and Can Tho Water Supply and Sewerage Company (WSSC) completed
a 2-year collaborative research project assessing the wastewater
infrastructure options for Can Tho City. The comparison of
alternatives was made on the basis of cost-effectiveness and on the
relative sustainability of the options, as determined through a
participatory stakeholder sustainability assessment process with
several government agencies in Can Tho.
The study compared four wastewater management alternatives for
the new urban area of South Can Tho with an area of 2080 hectares
and likely to house more than 250,000 people in the future. The
intent was to examine the applicability of recent innovations and
international trends in wastewater management. Alternatives
considered include centralised treatment (Option 1), decentralised
treatment at the scale of several hundred households (Option 2), a
combination of centralised and decentralised (Option 3, as shown
below) and an option with resource recovery in decentralised areas
(Option 4). The resource recovery option involves urine diversion and
storage for use as fertiliser in nearby agricultural areas.
