Nov. 19 - KEYS First Results Workshop


On November 5th, 2019 KEYS’ “First Results Workshop” & the “Mid-Term Meeting” took place in Beijing. German and Chinese partners spent the whole day together in discussing the results and concrete plans for the second half of the project in detail. As part of KEYS’ Demonstrations the R&D activities of the Company STEINHARDT und NIVUS drew the attentions from the audience again. The Company STEINHARDT has introduced how to apply their technologies of HydroGuard® and HydroTwister® into the Chinese Mega Water Project "Sponge City Tongzhou" (Beijing). Since the Company NIVUS has installed Flow Meters and Rain Gauges in Tongzhou in July 2019, they were able to present and share the data collected until November 2019 during the meeting. Other results of KEYS regarding Retention Soil Filters, Sponge City Elements and Waste Water Treatment Modelling have been presented und triggered further discussions between partners from both countries. In the afternoon session two workshops focusing on topics of “Sponge City” and “Waste Water Treatment Modelling” have been organized, in order to improve the further implementation steps of KEYS to the current and real situation in China. The KEYS project succeeds in keeping pace with the rapid development in China and works closely with the Chinese partners to make a great visible contribution to the Sponge City Development in Tongzhou (Beijing).

Sep. 19 - The KEYS demonstrations are progressing well

Our work on the demonstrations is progressing successfully. In July 2019, further coordination for the Steinhardt demonstrations was carried out. In September the NIVUS equipment was handed over in Beijing sustained by training measures and a large workshop on online-monitoring.

能科技 - 城市流域水资源的可持续管理 - 海绵城市

KEYS stands for Smart Technologies for Sustainable Water Management in urban Catchments as Key Contribution to Sponge Cities. KEYS addresses the topic of Sponge City and is the German contribution to the Chinese Mega Water Project "Sponge City Tongzhou", which is being implemented by Tsinghua University and numerous further partners in Beijing.

In the context of Research for Sustainability (German FONA Programme), KEYS is an expression of the continuation of the successful technical-scientific cooperation between China and Germany in the field of urban water management. The project is implemented in close cooperation with the School of Environment at Tsinghua University and strengthens the scientific ties. The strong network of science and industry as well as the local demonstrations make a significant contribution to ensuring that young scientists have the opportunity to obtain qualifications and that the participating companies can further improve their market access in China.
