People's Daily | The First Technical Guideline for Underground Municipal Wastewater Treatment Plant Issued in China
The first Technical Guideline for Underground Municipal Wastewater Treatment Plant (the “Guideline”) in China, which was formulated under the leadership of the CWEG, was officially issued by China Association of Environmental Protection Industry (CAEPI) on December 19, 2019 and implemented since January 2020.
Fan Yuansheng, chairman of the CAEPI, said that the introduction of the Guideline met the needs of the market and innovation. Jointly compiled by enterprises, colleges/universities and design institutes, it is endowed with advancement and universality and represents the highest level of underground plant in the field of research and practice.
At present, the underground WWTP is in rapid development in China. Compared with the traditional aboveground WWTP, the underground WWTP has the advantages of intensive use of land, environmental friendliness and better resource utilization, and can effectively solve the not-in-my-back-yard problem, release the ground space and achieve good resource utilization. However, as a new form of WWTP, there has been no targeted technical specification or guideline for underground plants in China. In spite of lots of engineering practices in China, the design and construction of the underground WWTP is mainly based on the standard system for traditional municipal WWTPs. Therefore, it is of great significance to formulate targeted standards based on practical experience and existing standards to promote the standardized development of the underground plants.
“The Guideline specifies the technical requirements for the design, construction, operation and maintenance of underground municipal WWTPs, fills in the blank of standards in this field in China, and will play a positive role in guiding the standardized development of market in this field,” chairman of the CAEPI Fan Yuansheng said.
As an important measure of national standardization reform, the State Council printed and issued the Plan for Deepening the Standardization Reform (Guo Fa  No. 13), which clearly proposed the cultivation and development of group standards, the stimulation of vitality of market subjects, the improvement of the standards supply structure, and the establishment of a new standard system which enables the synergetic development and mutual support between standards formulated under the lead of government and those formulated under the lead of market.
Dr. Hou Feng, the first author of the Guideline and chairman of CWEG, said that since its being approved for compiling in 2017, the Guideline has experienced such stages as investigation and research, preparation of the first draft, public consultation, submission for review, etc., and has gone through more than 20 domestic and international investigations and more than 10 thematic discussions, gathering the wisdom and consensus of the industry.
“The issuance of the Guideline has not come easily. It is the results of joint and painstaking efforts made by the management unit, the compilation committee members and evaluation experts,” Dr. Hou Feng said. “CWEG was entrusted to take the lead in formulating the guideline for underground WWTPs, which represents the high recognition and trust of the industry. We are willing to work with the government, the academia and the common people to make the underground WWTPs better and better to serve the water environment governance cause of the state.”
As a professional water environment business platform under the State Development & Investment Corp., Ltd. (SDIC), CWEG is the leader in the water environment comprehensive treatment industry in China. It independently owns a high-quality underground WWTP with treatment scale ranking first in Asia and even in the world, and established high-quality underground WWTPs in 19 provinces and cities, including Beijing, Shanghai, Erhai (Dali) and Chengdu. Meanwhile, it is also the unit leading the “Innovation of WWTP Construction and Demonstration of Ecological Complex” project, a major water project under the “13th Five-year Plan”. Its scientific and technological achievements play an important role in water environment treatment, and one of its projects was named the National Water Special Achievements Transformation Demonstration Base under the “13th Five-year Plan” by the Ministry of Housing and Urban-Rural Development.
