Study on Hanoi water pollution and drainage management approaching closure

Hanoi has grown rapidly into a modern, vibrant city. It is also envisioned to become a centre of culture, science, education, economics, tourism and international trade in the Asia-Pacific region. However, the development of infrastructure and services has lagged behind the growth of the population, hindering the realization of such vision. In particular, sustainable water resources management is a major challenge. Water pollution and urban flooding have arisen as persistent environmental problems in Hanoi for years, impairing the liveability of the city, deterring investors and compromising social – economic development.

Hanoi City Drainage Master Plan addresses these two issues but its implementation has not kept pace with the growth of the problems. Making Hanoi a water pollution and flood free city by 2050 will require enormous and sustained investment and institutional reform.

In an effort to support Hanoi City to implement its Drainage Master Plan and to build resilience and sustainability in the City’s water resources management, in 2019, the World Bank commissioned ICEM to undertake a study on water pollution control and drainage and wastewater management in Hanoi. The study aims at developing an effective and comprehensive management and investment program to tackle water pollution in key rivers – To Lich, Nhue, Day and Tich, and improve drainage and wastewater management in prioritized locations – Long Bien and Gia Lam districts.

Through a series of stakeholder consultations, field inspections, and data analysis, the study team assessed the baseline conditions of water pollution in the four rivers and urban flooding and wastewater management in the two districts, delineated the causes, and identified bottlenecks in addressing such causes. The technical challenges include rapid population growth and urbanization, dwindling water resources in rivers, infrastructure deficit (i.e. shortage of wastewater […]
