Under the wave of the “toilet revolution” and toilet technology innovation, we started with squatting pan without trap and aimed to achieve the goal of technological innovation and saving water resources by installing water-saving devices on the existing squatting pans. The water-saving reforming device for squatting pans has a simple structure and is easy to install. And the materials used have advanced scientific features. The device can solve the problems of over much water consumption and uncleanness of existing squatting pans. This water-saving device has strong economic value and outstanding environmental performance. Compared with other water-saving solutions, this design takes into account the demands of the entire chain of stakeholders in production, installation and use. Therefore, it can be easily applied and popularized.

Abstract Establishing and perfecting the water rights system is an important way to alleviate the shortage of water resources and realize the optimal allocation of water resources. Agriculture is an important user of water in various water-consumption industries, the confirmation of water rights in irrigation districts to farmers is the inevitable requirement for implementing fine irrigation in agricultural production. In this paper, a double-level water rights allocation model of national canals – farmer households in irrigation district is established. It takes into account the current water consumption of the canal system, the future water-saving potential and the constraint of total amount control at the canal level. It takes into account the asymmetric information of farmer households’ population and irrigation area at the farmer household level. Furthermore, the Gini coefficient method is used to construct the water rights allocation model among farmer households based on the principle of fairness. Finally, Wulanbuhe Irrigation Area in the Hetao Irrigation Area of Inner Mongolia is taken as an example. The results show that the allocated water rights of the national canals in the irrigation district are less than the current because of water-saving measures and water rights of farmer household get compensation or cut respectively. The research has fully tapped the water-saving potential of irrigation districts, refined the distribution of water rights of farmers and can provide a scientific basis for the development of water rights allocation in irrigation districts and water rights transactions between farmers.

Abstract Because of the shortage of water resources, the phenomenon of groundwater over-extraction is widespread in many parts of the world, which has become a hot issue to be solved. The traditional idea of water resources management only considering blue water (stream flow) can't meet the demand of sustainable utilization of water resources. Blue water accounts for less than 40% of total rainfall, while green water (evapotranspiration) accounts for more than 60% of total rainfall. In the natural environment, vegetation growth mainly depends on green water, which is often neglected. Obviously, the traditional water resources management without considering green water has obvious deficiencies, which can't really reflect the regional water consumption situation in the water resources management. And only by limiting water consumption can achieve the real water saving. In addition, the mode of water resources development and utilization has changed from "supply according to demand" to "demand according to supply". In this background, for many regions with limited water resources, it is impossible to rely on excessive water intake for development, and sustainable development of regional can only be realized by truly controlling water demand. This paper chooses Shijin Irrigation District in the North China Plain as the research area, where agricultural water consumption is high and groundwater over-extraction is serious, and ecological environment is bad. In order to alleviate this situation, comprehensive regulation of water resources based ET is necessary. Therefore, this paper focuses on the concept of ET water resources management and includes green water into water resources assessment. Based on the principle of water balance, the target ET value of crops in the study area is calculated, and the ET value is taken as the target of water resources regulation. The actual water consumption is calculated by Penman-Monteith formula, and reduction of crop water consumption is obtained according to the difference between actual ET and target ET. The reduction in crop water consumption leads to a reduction in demand for water supply, which reduces groundwater extraction. The results of this study can provide necessary technical support for solving the problem of groundwater over-extraction and realizing real water saving.

AbstractDue to uncertainties in water supply, there is growing demand for water resource management in enterprises. In this study, we evaluated the effects of companies’ water-saving reconstruction projects. We used Hina Advanced Materials Company as a case to construct an investment decision model to (1) calculate the internal and external costs of water resources based on circular economic value analysis theory, and (2) locate the level of water resources circulation. We adopted gray situation decision analysis to identify the typical problems that occur in water resource utilization. Moreover, we demonstrated optimization plans for different potential improvements, thereby providing guidance and references for water resource cost management and the comprehensive optimization of environmental benefits. We concluded that the circulation economic value analysis model can effectively display the flow and amount of value derived from water resource flows, thereby providing guidance and suggestions for optimizing water resource flows.

This article presents a systematic approach to solving a problem with rational use of an airport’s water resources. Life cycle programming of the technological systems of wastewater purification allowed to consider comprehensively the problem of economical water consumption. The life cycle programming was adopted as the methodological basis for constructing a logical scheme of tasks of an airport’s water-saving processes. On the basis of the proposed logical tasks diagram it became possible to develop an algorithm and software for automatized control over airport’s water-saving processes. The purpose of the work is to implement a systematic approach for control over water-saving production aviation processes of the airport and representation of the developed algorithm for control. It may be concluded that the implementation of the given algorithm on the basis of computer technology will increase the efficiency of wastewater purification and significantly reduce the fresh water consumption.

Although Turkey's total agricultural land not decrease occurred over the years thanks to the presence of land brought into production economically in irrigated maize quality aquaculture operations have become widespread in Turkey. Maize in areas where watering is possible; it is a popular product in terms of aquaculture because of low labor costs, high efficiency advantage in unit area and easy access of the product market. The increase in irrigation areas in parallel production of maize; It is a product with high economic value but high water consumption. In this aspect, the aim of the study is to make analyzes about the sustainability of the agricultural activities, the solution of the problems encountered in the process from the sowing of the crop to the harvesting, and the expectations of the farmers. In the study, it was determined that agricultural operators have future concerns about input costs, storage facilities and consumption of water resources.

The article examines the problem of fresh water, since in terms of water supply from its own resources per capita and per 1 km2, the republic is 8 times behind Georgia, 2 times behind Armenia. Significant water consumption in Azerbaijan is caused by its arid territory with a predominance of active temperature and a lack of precipitation, which leads to intensive irrigation of crops. At the same time, artificial irrigation is used on 70% of the cultivated land.
