3.11.1 The study on urban drainage and wastewater disposal system in Hanoi
Study Period : October 29,1993-February 28,1995
Counterpart Agency : Hanoi People's Committee
Socialist Republic of Viet Nam
Background
Hanoi is the capital city of Viet Nam, which is the political, economic, and
cultural center of the country. The Government of Viet Nam (GOV) has long been
keen to improve the drainage and wastewater disposal systems as quickly as
possible in order to sustain Hanoi's economic growth and hygienic improvement.
Existing drainage and wastewater disposal systems are falling into a state of
disrepair and their conveyance capacities are being reduced (Photo 3.1). This
results in frequent flooding of the urban area and deterioration of water
quality in rivers and lakes of the surrounding areas. These have been creating
serious problems for the environment and have hampered economic development
activities. In recent years, several peripheral areas have been subject to rapid
population increase and development without provision of adequate drainage and
wastewater disposal systems. This further aggravates the problems (Photos 3.2).

Objective
The Study's objectives are: (1) to formulate a master plan
(target year: 2005) on urban drainage and wastewater disposal systems in the
central part of Hanoi City (almost 135km2) and (2) to conduct a feasibility
study (F/S) on urban drainage systems and/or wastewater systems for the
prioritized projects selected in the master plan.
