Suez secures contract for sewer and stormwater systems optimisation in Chongqing

Water and waste management firm Suez Environment has secured the contract for the performance optimisation of sewer and stormwater systems in Yuelai, Chongqing in China.

The firm will deploy its digital solution AQUADVANCED Urban Drainage, which will enable the local authorities to monitor the sewer and stormwater networks in real time to minimise the risk of flooding and to control the quality of discharges.

The contract is part of the Sponge City programme launched by the Chinese government to increase the resilience of the cities’ to the risk of floods.

To be deployed on a surface area of 18.7 km², the solution will see an investment of €4m and will be initially launched in April in Yuelai, with plans to extend to other neighbourhoods in the city.

It is expected that the solution will offer a global, real time vision of the entire system based on data from sensors that are installed in the network and in the receiving environment, as well as on short-term weather forecasts.

The software solution will centralise and analyse this data, enabling authorities to control the risk of floods and limit the pollution of the Yangtze river.

The drainage solution has already been deployed in approximately 20 cities such as the Paris agglomeration, the Bordeaux metropolitan area, Barcelona and Singapore.

Since 2002, Suez has been supporting Chongqing authorities in improving the water distribution network and the treatment of urban and industrial wastewater.
