Valves for Wuxi's expanding water treatment plant

Wuxi, a metropolis midway on the railway line from Shanghai to Nanjing, is also referred to as the 'Lustrous Pearl of Lake Taihu'. The excellent train connection to Shanghai, which is 100 km away, has enabled the city to grow exponentially in recent years.

At the end of 1998, the city had 4.4 million inhabitants; at the end of 2010, it had over 6 million. In order to supply all of the inhabitants with drinking water from Lake Taihu, WXGS (Wuxi General Water Supply Company) built one of the first water treatment plants in 1991. The funding, the technology and the plants all came from abroad.

Wuxi's Zhongquiao water treatment plant, which is in the south of the city, was planned by the municipal engineering firm Shanghai SMEDI (Shanghai Municipal Engineering Design Institute) and built in phase 2 by Siemens AG.

The new activated carbon filtration process for the removal of ozone was built in 2010. This process increased the plant's capacity fourfold to 600,000 m3 per day. This was the project's largest building phase.
