Quality water services to support Chongqing's rapid development
Chongqing, as China's youngest direct-administrated municipality and the head city of China's Western Development, is the first city offering the concession license upon the opening of the Chinese urban water supply network, and also the city where SUEZ won its first full-scale water supply contract in China. Since 2002, we've taken charge of the water supply and network management services in Jiangbei District, Yubei District and North New Zone of Chongqing.
Water supply dilemma of the mountain city
Chongqing, known as a mountain city, is located in the upper reaches of the Yangtze River, with fresh water resources and water quality far higher than the national average level; however, because of its unique geographical features, the city is troubled by difficulties with water transportation and high cost.
In the past decade or above, Chongqing has maintained a GDP on double-digit growth, which leads the country. With the rapid economic development and urbanization pace, Chongqing's water consumption keeps rising; likewise, the network coverage continues to grow. Water enterprises in this case have to speed up the pace of construction while maintaining quality water supply and service stability.
Reinforcing constructions to meet Chongqing's water demand
Since SUEZ took charge of water production and delivery for the northern areas of Chongqing in 2002, first of all, it undertook an automation system renovation over the original water plant, to achieve the real-time production monitoring and remote control all over its service area. In 2009, the company began its investment and construction of the Yuelai water plant to catch up with the increasing demand for water supply in the three northern areas of Chongqing. The construction consists of three phases. Currently the first and second phases, with design capacity both at 200,000 tons/day, have been completed and put into operation.
Through introduction of SUEZ advanced management and technology, Chongqing's water supply management capacity, tap water quality and customer service level has been hugely upgraded, specific performance as below:
- The daily water supply capacity rose from 345,000 m3 to 940,000 m3; the length of network increased from 272 km to 1,807 km; and the number of users grew from 36,000 to 1,050,000 households.
- As we adopted GIS system and technical renovation, the rate of non-revenue water was lowered from the initial 30% to the current 14.82%.
- We introduced the LIMS system into the central laboratory, and the lab was rated as "benchmark laboratory" in SUEZ's international laboratory competence comparison, and was accredited as China National Accreditation of Laboratories (CNAL).
- We set up a 24-hour call center to provide customers with a full range of quality services; undertake regular annual customer satisfaction surveys to grasp and understand the needs of customers in order to further improve the services.
