Waste water treatment plants and water treatment plants in Shenzhen special economic zone are operating, planning and constructing by Shenzhen Water Group. We invited an engineer of Shenzhen Water Group in order to make a speech regarding to plan, construction and operation of wastewater and water treatment plants. Therefore, the aims of this workshop were to make the present condition of Shenzhen city reflect in the subject of research which each faculty set up. On the other hands, actual condition and future plan of wastewater treatment plants and water treatment plants were explained from Japanese participants and it was expected that these lectures deepen a mutual understanding. Moreover, water treatment plant which is in Osaka city and wastewater treatment plant which is in Otsu city were visited following this workshop.


Challenges Faced by Sewage Works in Japan was explained by Mr. Fujiki who is a chairman of the managing committee of GCUS. Next, Consumers' Needs for Drinking Water Quality and Prospects of Japanese Waterworks was introduced from Prof. Itoh. Future Development of Water and Sewage Works in the Southern Area of China was mentioned from Prof. Zhang who belongs to Shenzhen water group.

GCOE program and EML program were introduced from leader of each program, that is, Prof. Matsuoka and Prof. Fujii, respectively. And also, present activities of Shenzhen base were reported from Assoc. Prof. Yasojima. Development of Resource Recycling Type Urban Wastewater and Solid Waste Processing System and Its Component Technologies, Water Reuse for Win-win Solution and Next-Generation Drinking Water Treatment System were presented from Assoc. Prof. Nishimura, Prof. Tanaka and Assoc. Prof. Echigo, respectively. A keen discussion regarding to technologies of Japan was carried out after these presentations. Moreover, from the Japan side, the question regarding the Shenzhen water group's scope of work and to the expectation for new technology was performed. Thereby, an understanding of both researches and activities was further deepened through this workshop.
Following on the workshop, the facility visit of the Murano water treatment plant in Osaka city was carried out. The participant was interested in the following. That is, although the original water of this water treatment plant is the water in which the repetition was used, the participant got interested in the water treatment plant having the ability to supply drinking water as a result of water treatment.
In March 6th, Konan-chubu wastewater treatment plant which has the technology of the record level in Japan was visited. In this wastewater treatment plant, the treatment called "ultra advanced treatment" has achieved drastic reduction of nutrients. For this reason, the question regarding a treatment system etc. was repeated. An understanding regarding the water-and-sewage works of Shenzhen city was deepened through this workshop and the site visit. By this workshop, we were able to build an even better relationship between Kyoto University and Shenzhen water group.
