Yuan Shui Company
Yuan Shui Company has a Type II reservoir, Dalangdian Reservoir, under its jurisdiction. According to the Group's business division of labor, Source Water Company is mainly responsible for reservoir management, inspection, maintenance and repair, water diversion and storage, and raw water supply.
Dalangdian Reservoir is the first plains reservoir in our province, located 22 kilometers south of Cangzhou city, is the only centralized water supply source in Cangzhou city. The reservoir covers an area of 31,225.27 acres, with a total capacity of 100.3 million cubic meters, a dead storage capacity of 4.64 million cubic meters, a hingli storage capacity of 95.66 million cubic meters, and an annual water supply capacity of 81.21 million m3, a design level of 12.471m, a dead storage level of 6.471m, a storage area of 16.89 square kilometers, and an enclosing embankment of a total length of 16.61km. the reservoir's annual evaporation of 2.06 million cubic meters is about 20% of the total storage capacity, and the annual evaporation is about 20% of the total storage capacity. The annual evaporation of the reservoir is 2006 million cubic meters, accounting for about 20% of the total reservoir capacity, and the annual infiltration is 8.32 million cubic meters, accounting for about 8.3% of the total reservoir capacity.
Dalangdian Reservoir is the main source of water supply for Cangzhou City, and currently draws water for storage once a year, and the routes for drawing water include drawing yellow water into the precipitation and Wangda water diversion, the former from Liaocheng, Shandong Province, and the latter from Wangquan Reservoir in Baoding. Since put into use, the Daliandian cumulative storage 12 times, *** storage of nearly 600 million cubic meters of water, of which 11 times is the introduction of yellow into the precipitation, only in 2005 to use the Wangda water diversion storage once.
Dalangdian main water supply target for the city of Cangzhou, the introduction of large into the harbor along the reservoir around Nampi, Botou and other counties. Since the completion of the cumulative water supply of more than 370 million cubic meters.
In order to ensure the safety of urban water supply, Daliandian has been fully closed management in recent years. And because of greening and other measures, the reservoir water quality indicators have been maintained in the surface water Ⅱ class water quality standards, better than the drinking water source Ⅲ water quality requirements.

Water supply company under the jurisdiction of three water plants, including two surface water plants, underground water plant. Surface water plants are the East Water Plant and Qingyuan Water Plant, designed production capacity of 100,000 cubic meters / d. Underground water plant for the West Water Plant, in a standby state, designed production capacity of 50,000 cubic meters / d.

Plant covers an area of 130 acres, with a total investment of 22,100,000 yuan, started in May 2003, completed in November 2004, the design scale for the daily treatment of sewage 100,000 cubic meters, water 30,000 cubic meters. After the completion of the sewage plant won the 2005 National Construction Engineering Highest Award - Luban Award. Meanwhile, Yundong plant has become the first sewage treatment enterprise in China to pass the certification of ISO9001, ISO14001 and OHSAS18000 through comprehensive strengthening of internal management.
Yundong plant for the Cangzhou Chemical City, high ammonia nitrogen, low BOD characteristics, the project adopted the internal reflux anaerobic, aerobic and microporous aeration oxidation ditch wastewater treatment process, the design of the effluent quality of water to meet the national "Comprehensive Wastewater Emission Standards" (GB8978-1996) of the second level standards. 2004 September trial run, the sewage effluent and water effluent water quality all meet the standards, in particular, the effluent Ammonia nitrogen removal rate of more than 98%, the effluent is only less than 1mg / l, the treatment effect is much better than the design of the effluent standard.
The water reuse project was formally completed in September 2004, and the main indicators of the effluent water quality are better than the comprehensive water quality standards for water reuse in industrial recycling cooling water, municipal miscellaneous water, and landscape water.
Yundong started supplying water to the China Resources Thermal Power Plant in April 2008, with sales of 3,260,000 m3 in the same year. At present, the average daily supply is 20,600,000 cubic meters.
