A large amount of rainwater in a short period of time will cause a city's drainage system to overload and put heavy pressure on a city's water management system and cause inconvenience in the community.

A number of enterprises focusing on water treatment will bring their star products to this year's China Hi-Tech Fair (CHTF), which will take place at the Shenzhen Convention & Exhibition Center in Guangdong province from Nov 17 to 21.

The intelligent water management and control platform developed by Shenzhen-headquartered NewGround Environmental applies advanced technologies like online monitoring, big data analysis, model simulation, and internet of things.

Its intelligent drainage operation monitoring system can sense the operating status of drainage facilities in real time and provide a visual information management tool for urban drainage.

Shenzhen Doctor Rainwater Recycling's integrated rain water module is an important part of the rainwater collection system for constructing sponge cities. Rainwater resources collected through the module can be used to flush toilets and water lawns.

Datang Convergence (Harbin) Ecological Environment Technology, a subsidiary of Datang Telecom Convergence Communications, can provide an "internet + digital intelligence" solution for rural sewage treatment. Its self-developed rural sewage treatment system will be on display at this year's CHTF.

Suzhou Dingdedian Environmental Protection Technology will also be exhibiting at the fair and has been focusing on water pollution and soil pollution control. Its products can sterilize and manage the degradation of COD as well as the flocculation of particulate matters in industrial wastewater and sanitary sewage.
