Water is an essential resource for human survival, and our country suffers from a severe shortage of water resources. As urbanization accelerates, weak awareness of water resource conservation and irrational utilization of water resources are leading to an increasingly prominent imbalance between supply and demand for freshwater resources. The fundamental ways to resolve the supply-demand imbalance are, first, increasing supply, and second, reducing demand. Due to certain limitations of open-source solutions, throttling has become the main water resource strategy in the near term. Industrial enterprises have always been major water consumers, and water conservation in industry is an effective measure to alleviate the supply-demand imbalance of water resources in our country. In recent years, our country has introduced a series of policies to strongly support water conservation in industry. Four departments jointly issued the \"Guiding Opinions on Strengthening Urban Water Conservation Efforts\". In order to improve the level of intensive and efficient use of urban water resources, enhance the systematic approach to water conservation in cities, and further advance urban water conservation efforts, the Office of the Ministry of Housing and Urban-Rural Development, the Office of the **National Development and Reform Commission, the Office of the Ministry of Water Resources, and the Office of the Ministry of Industry and Information Technology issued the \"Guiding Opinions on Strengthening Urban Water Conservation Efforts\" (hereinafter referred to as the \"Guiding Opinions\"). The Guidelines emphasize the need to vigorously promote water conservation in industry. Strengthen the management of water consumption quotas in industrial enterprises, carry out benchmarking for water efficiency, actively apply advanced and suitable water-saving technologies and equipment, and implement water-saving renovations. Increase the use of unconventional water resources such as industrial wastewater, reclaimed water, rainwater, and seawater. Cities facing water shortages in the Beijing-Tianjin-Hebei region and the Yellow River basin should encourage the operators of municipal sewage treatment and reuse facilities to collaborate with key water users and industrial parks, so that municipal sewage and reclaimed water can be used as important sources of water for industry. This will help reduce companies’ reliance on fresh water, thereby creating a new model for efficient recycling of wastewater in integrated industrial and urban areas. Efforts should also be made to develop pilot projects that can be replicated and expanded. Improve the enterprise water monitoring and metering system to enhance water use efficiency. Five departments have issued the \"14th Five-Year Plan for Building a Water-Saving Society\". In order to thoroughly implement the concepts of ecological civilization, carry out the \"14th Five-Year Plan for National Economic and Social Development of the People’s Republic of China and the Long-Term Goals through 2035\", continue with water-saving initiatives, and accelerate the development of a water-saving society, five departments including the National Development and Reform Commission and the Ministry of Housing and Urban-Rural Development have jointly issued the \"14th Five-Year Plan for Building a Water-Saving Society\" (hereinafter referred to as the \"Plan\"). The Plan states that efforts should be made to reduce water consumption and pollution in industry. Strengthen the management of water consumption quotas in water-intensive industries. Key enterprises carry out water balance testing, water use performance evaluation, and water efficiency benchmarking. Promote the application of advanced and suitable water-saving technologies and equipment, carry out water-saving upgrades in enterprises, advance the hierarchical and recycled use of water within these enterprises, and increase the rate of water reuse. Implement projects for the resource utilization of industrial wastewater, focusing on industries such as thermal power, steel, petrochemicals, non-ferrous metals, papermaking, printing and dyeing, and food processing, to establish a number of model enterprises for the resource utilization of industrial wastewater. By 2025, 50 industry leaders in water efficiency will be selected from sectors such as thermal power, steel, petrochemicals, non-ferrous metals, papermaking, printing and dyeing, and food processing. The Regulations on Water Conservation in Hebei Province: In May this year, the 23rd session of the 13th People’s Congress of Hebei Province approved the Regulations on Water Conservation in Hebei Province (hereinafter referred to as the “Regulations”). The Regulations emphasize giving priority to water conservation, implementing the strictest water resources management system, and establishing a rigid framework of constraints on water resource use throughout the entire process of water extraction, as well as in all sectors and areas of economic and social development. They focus both on addressing existing problems and on achieving set goals. The Regulations emphasize that industrial enterprises should strengthen internal water management, establish water-saving management systems, promote water-saving technologies and processes such as efficient cooling, washing, water recycling, reuse of wastewater, and the replacement of water-intensive production methods, in order to build water-saving enterprises. Industrial enterprises are encouraged to appoint water managers to strengthen water use management. The National Development and Reform Commission and the Ministry of Water Resources have issued the **Water Conservation Action Plan**. In order to implement the spirit of the Party’s guidelines, to promote water conservation across society, to improve the efficiency of water resource utilization, to foster a water-conserving pattern of production and lifestyle, to ensure **water security**, and to advance high-quality development, the National Development and Reform Commission and the Ministry of Water Resources have issued the **Water Conservation Action Plan** (hereinafter referred to as the \"Plan\"). The Plan states that efforts should be made to advance industrial water-saving renovations. Improve the water supply and consumption metering system as well as the online monitoring system, and strengthen the management of production water. Vigorously promote water-saving processes and technologies such as efficient cooling, washing, recycled water use, reuse of wastewater, and the replacement of water-intensive production processes. Enterprises are supported in carrying out water-saving technological upgrades and recycled water reuse improvements; key enterprises should regularly conduct water balance tests, water use audits, and efficiency benchmarking. Enterprises that exceed the water withdrawal quota standards shall undergo water-saving renovations in a classified and phased manner within a specified time frame. Strengthening water management is an important aspect of water conservation in industry. Only by strengthening enterprise water management can water resources be used rationally to achieve both increased production and water conservation. Industrial enterprises must have in place water use plans, water conservation goals, water-saving measures, and water management systems. (1) Conduct regular water balance tests. Water balance testing is an important fundamental task for enterprises to implement planned water use, promote water conservation, and allocate regional water resources in a rational manner. Through water balance testing, the current water usage situation of the enterprise is determined, and the various water volumes used by different water-consuming equipment or processes within the enterprise are identified ； Identify the weak points in a company’s water usage and assess its water consumption level ； Uncover the water-saving potential of enterprises to provide a basis for formulating water-saving measures and rationalizing water use quotas. Jinma Company adheres to actual data measurement; by using balance of water tests management software, it systematically analyzes the problems present in various water usage stages. Based on the available information and collected data, it conducts scientific calculations, analyses, and evaluations of relevant technical and economic indicators related to water use, identifies weak points, explores potential for water savings, and provides reasonable recommendations for the company’s water usage ； Increase the reuse rate of water while meeting various water demands, thereby achieving water conservation. (2) Conduct regular pipeline leakage inspections. By carrying out regular checks on buried pipelines for leaks, it is possible to identify leak points promptly and take corrective actions. This not only helps to reduce economic losses caused by pipeline leaks but also eliminates safety hazards, contributing to safe production in enterprises. Over the years of carrying out leak detection tasks, Jinma Company has employed non-destructive testing methods and relied on advanced detection technologies to gain extensive experience in this field. It has been able to assess the current situation of leaks in water supply networks, accurately locate the source of leaks, determine the amount of water leaking from each site, identify patterns in these leaks, analyze their causes, and thereby reduce water losses.
