Ningxia NINGDONG Energy and Chemical Industry Base implements the requirements of the pilot construction of “Four Water Four Settings”, gives priority to water conservation, focuses on water-based production, promotes the optimization and upgrading of industrial structure, actively cultivates new water-saving industries, guides enterprises to change their water consumption mode, improves water consumption efficiency, improves the park's water resource management system, and builds the first batch of water-saving parks in the whole region and the first national industrial wastewater recycling pilot park in the northwest of China. It will be the first water-saving park in the region and the first national industrial wastewater recycling pilot park in Northwest China.

Wang Xuelei, head of the Natural Resources Bureau of Ningdong Base Management Committee, said, "As of March 2025, the water consumption of 10,000 yuan of industrial added value will decrease by 21% compared with the end of the 13th Five-Year Plan, the amount of non-conventional water consumption will increase year by year, the comprehensive utilization rate of mine water will increase by 53% compared with that of 2020, and the utilization rate of recycled water will reach 100%, and the industrial water consumption of key monitoring water-consuming enterprises will reach 100%. 100%, the industrial water reuse rate of key monitoring and control water enterprises reached 98%, and the completion rate of water-saving enterprises with annual water consumption of more than one million cubic meters reached 96%."

Ningdong Base has built a water integration digital platform to realize refined, information-based management of water resources, connecting water use - water rights - management, realizing efficient use of water resources through refined dynamic management, and solving the contradiction between growing industrial water use and limited water rights.

Deeply promote industrial water conservation and efficiency, strictly control all kinds of new high water-consumption projects, and promote the withdrawal of water to the modern coal chemical industry, new materials, fine chemical industry, clean energy and other advantageous characteristics of the industry tilt.

Vigorously carry out industrial water efficiency improvement action, promote enterprises to carry out water efficiency leader, water saving benchmark and water-saving enterprise construction work, the park has built a national water efficiency leader, autonomous regions, 3 water saving benchmark enterprises and water saving enterprises 38.

Ningxia and Ning Chemical Co., Ltd. is a key project of investment in the autonomous region. The company comprehensively promotes the construction of water-saving enterprises by strengthening the basic management of water consumption, increasing the efforts of water-saving technological transformation, and endeavoring to reduce costs, etc., and has made remarkable achievements in water-saving work. Arranging special funds to promote the development and application of water-saving technology, the company started the construction of the water reuse “near-zero discharge” project in July 2019, and the water reuse device was put into operation in January 2021, with a treatment capacity of 280 cubic meters per hour. The wastewater discharged from the wastewater treatment plant and the concentrated brine discharged from the desalination station will all be reused in production after treatment, saving about 1.2 million cubic meters of new water annually.

In November 2023, the management committee of NINGDONG base reached a three-year total of 15 million cubic meters of Yellow River water right deal with Aba Prefecture of Sichuan Province, allocating it to industrial projects in the park to guarantee water use, which is the first inter-provincial regional water right deal in the country.

Ningxia Best Pharmaceutical & Chemical Co., Ltd. applied for a combined financing loan of RMB 9 million from Ningxia Lingwu Rural Commercial Bank Co., Ltd. in Ningdong Sub-branch. Ningxia Ningdong Financing Guarantee Co., Ltd. guaranteed its water right as a mortgage, completing the “first” industrial water right pledge loan financing of the Ningdong base, activating the commodity attribute of the water right.

Explore the establishment of dynamic management and revitalization of water rights in the park, water rights storage and regulation, planned water management, regional water commitment filing management system, government guidance, market deployment, multi-party participation, real-time trading of water rights between enterprises, flexible flow, dynamic regulation, release the maximum vitality of the water rights stock, to create a NINGDONG base “water assets” commodity value demonstration zone. Commodity value demonstration area.

In recent years, NINGDONG base actively promote the recycling of industrial wastewater, high-standard promotion of non-conventional water resources utilization, treatment facilities and pipeline network construction, built a township sewage treatment plant, park public sewage treatment plant 5, wastewater “near-zero discharge” project 11, to achieve wastewater treatment and reuse. Sheep field bay, stone groove village and other 5 coal mine mine water depth treatment facilities and 11 coal mine water pre-treatment system, after treatment of mine water to meet the standards of priority for industrial projects and park landscaping, the new pipeline 152 kilometers, 13 coal mines, fresh water and mine water to achieve online monitoring for three consecutive years, the amount of mine water back to the amount of increase year by year.

Accelerate the promotion of mine water “water transfer” project construction, the realization of the Ningdong base mine water “south to north” for coal chemical projects, in order to increase the use of mine water to replace the Yellow River water resources. Since 2017, all recycled water in the park has been treated and reused, realizing that wastewater is not discharged, and building the first “zero-discharge” industrial park in China.
