The capital city of Hanoi will ban or limit investment in those economic and industrial zones which do not have concentrated wastewater treatment systems, in an effort to protect the environment.

The municipal Department of Planning and Investment is working with relevant agencies to study specific measures towards this goal in line with Deputy Prime Minister Hoang Trung Hai’s instruction, to be submitted to the municipal People’s Committee.

Meanwhile, the Department of Industry and Trade and management boards of industrial and processing zones have directed the zones’ investors to promptly complete concentrated sewage treatment systems and connect them with factories operating in the zones.

Local authorities around industrial zones have been urged to speed up the inspection of environmental protection and hold more educational campaigns to raise awareness of both businesses and locals of the protection work.

According to the Department of Industry and Trade, the city is building 107 industrial clusters, 48 of which have no plans for concentrated waste water treatment systems.

Among 42 operational industrial zones and clusters, only 25 have the required systems.

The department has plans to build the systems at seven industrial clusters in 2014, and at nine others in the following year.-VNA
