(Yicai Global) March 21 – The treatment of black odorous water is a difficult task as the main problem lies in direct discharge of sewage and the layout of cities' pipe networks, a senior official of the ministry of environmental protection admits.
Remediation of black odorous water is an important target mentioned in the 'Action Plan for Prevention and Control of Water Pollution' issued by the State Council, China's cabinet. It has a clear timetable. However, it is currently a daunting task, said Zhang Bo, director of department of water environment management, in response to a question by Yicai Global at a press conference by ministry of environmental protection.
"All institutions should proceed with the action plan timetable and finish the job by the end of the year. Ministry of environmental protection will take appropriate restrictive measures against institutions which wouldn't accomplish the mission," said Zhang Bo.
"The essence of the problem of black odorous water is the direct discharge of sewage, and the deep-seated problem lies in the unmatched city pipe network and sewage treatment plants," Zhang Bo told Yicai Global.
Data obtained by Yicai Global shows that 1861 rivers with black odorous water in the urban built-up areas were made known to the public for the first time in February 2016. However, the total number of rivers with black odorous water reached 2082 in February 2017, a net increase of 221.
The 'Action Plan for Prevention and Control of Water Pollution' issued by the State Council requires that major cities should basically eliminate black odorous water by the end of this year.
