Water recycling for a water-stressed region

Veolia has installed treatment technology capable of recycling 30% of the wastewater at this chemical complex so it can be used as cooling water.



Since 2010, Veolia has been managing the complete water cycle at the site of one of China’s largest chemical manufacturers, Tianjin Soda. As part of a “Design, Build, Own, Operate and Transfer” (DBOOT) contract set to run until 2035, the joint venture created by Veolia and its customer-partner will manage all of the site’s industrial water and wastewater treatment facilities. Veolia has pledged to maintain a uniformly high standard of availability and quality to meet its customer’s expanding needs.


In just a few years, Veolia has made substantial gains in efficiency at the facilities under its management so as to keep pace with the exponential growth in production at the chemical complex and help its customer reduce costs in the face of a highly competitive market. By meeting with the customer on a daily basis to assess fluctuations in production activity, Veolia can tailor its services to current conditions. This partnership has yielded ongoing service improvements as well as proposals for new solutions, such as the partial reuse of wastewater to reduce the site’s water footprint. Beginning in 2014, 30% of the treated wastewater will be fed into the site’s cooling systems.
The contract provides full-time employment for 83 Veolia employees, including 20 women. Given the size and complexity of the facilities, the site is a model of efficiency within China’s chemical industry.
