Activity in FY 2009
A workshop was organized in Hanoi not only to identify thecurrent situation of domestic wastewater management in theAsian Capital Cities and its issues but also to share theirexperiences and identify the common issues for the further.
 Low domestic wastewater treatment ratio are observed in many cities of
WEPA countries. In addition, the cities where wastewater treatment system
are developed also have some problems in operation.
 In order to solve water pollution in the city , not only how to apply
appropriate wastewater treatment technologies but also how to strengthen
the enforcement of policy/law/standard/plan are pointed out to be issues
for future discussion.
