Abstract:

Typical processes of water purification and water treatment of water park pools are considered. The method of economic estimation of efficiency of their application is offered. The methodology is based on the introduction of a number of indicators of the quality of the water treatment process of calculating the coefficient of “efficiency criterion” of water treatment of swimming pools. The purpose of this study was to develop an innovative technology of electrolytic-cavitation water treatment for swimming pools and water parks and to create a method of comparative evaluation of the effectiveness of modern water treatment technologies. A new technological scheme of electrolytic-cavitation water purification of public water bodies is proposed. A mathematical dependence has been created, which allows to objectively assess the effectiveness of various methods of water treatment and purification using the proposed indicator called “efficiency criterion” It is established that the proposed method of electrolytic-cavitation water purification has the highest values of efficiency from the considered water purification processes. This method is based on an organic combination of the advantages of such physical methods as electrolytic and cavitation disinfection of organic and biological water pollutants. The degree of purification and disinfection provided by him reaches 97-98%.

Abstract:

ESPOCH, an Ecuadorian university with a unique underground water source, is developing a drinking water plant to serve its population of over 22,000 students and staff members. The paper explores innovative measures and technology for efficient water utilization at ESPOCH, including a secondary, untreated water line for non-potable uses and the adoption of smart water management technologies to monitor and regulate water consumption. This approach addresses the provision of safe drinking water, plastic waste reduction, and health risks linked to poor water quality. ESPOCH's innovative water management approach contributes to the broader discussion on sustainable universities' role in managing water resources. The study highlights the importance of technology and innovation in resource conservation and utilization in higher education institutions, with ESPOCH serving as a valuable example for other universities addressing water scarcity, environmental impact, and promoting sustainable practices.

Abstract:

The objective of this study was to investigate the effect of nitrogen (N) management on soil water recharge, available soil water at sowing (ASWS), soil water depletion, and wheat (Triticum aestivum L.) yield and water use efficiency (WUE) after long-term fertilization. We collected data from 2 experiments in 2 growing seasons. Treatments varied from no fertilization (CK), single N or phosphorus (P), N and P (NP), to NP plus manure (NPM). Comparing to CK and single N or P treatments, NP and NPM reduced rainfall infiltration depth by 20–60 cm, increased water recharge by 16–21 mm, and decreased ASWS by 89–133 mm in 0–300 cm profile. However, crop yield and WUE continuously increased in NP and NPM treatments after 22 years of fertilization. Yield ranged from 3458 to 3782 kg/ha in NP or NPM but was 1246–1531 kg/ha in CK and single N or P. WUE in CK and single N or P treatments was < 6 kg/ha/mm but increased to 12.1 kg/ha/mm in a NP treatment. The NP and NPM fertilization provided benefits for increased yield and WUE but resulted in lower ASWS. Increasing ASWS may be important for sustainable yield after long-term fertilization.

Abstract:

Economic theory and recent empirical evidence show that nonlinear progressive water pricing policies are the most useful tool to reduce water demand in water stressed countries. The originality of our paper is to implement Pedroni (1999) panel cointegration tests, using databases on a breakdown of two consumption blocks (a lower and an upper block) from the Tunisian water regulator over 27 years. The results reveal that increasing block tariffs have been successful in managing scarce water in Tunisia. The authors observe that, in the long-run, proportion of subscribers in the upper water consumption block decreases when price increases, while in the lower block, which is composed essentially of low-income households characterized by inelastic water demand, proportion of subscribers is less elastic to price changes and still unchanged. This paper calls for the implementation of nonlinear progressive pricing to reduce demand by large consumers in order to promote efficiency in use and to promote the access of poor consumers to the resource in order to promote equity.

Abstract:

Abstract The quantity of management systems standards (MSSs) is increasing every year. Standards are significantly associated with common requirements and differences for many providers of services as well as for manufactures. The drinking water supply management system is certainly one of the important services. The aim of this article is to introduce a basic application of management system (MS) using visual management. The standard applied in a model, defined as a complex solitaire or “singlet”, is the Water Efficiency Management Systems (WEMS) standard. Visualised model is built by creating clusters using a software program designated for Small World Networks. This phase is preceded by the compilation of Excel spreadsheets, where requirements are divided into common and specific ones. The resulting cluster of selected areas includes the context of organizations that provide services, considering the common and specific requirements of interesting parties, managing their leadership, planning, support, operation, performance evaluation and improvement. It could be very useful to extend the cluster by another standard depending on the needs of the drinking water supplier and the transport piping systems at the site. This approach to management systems intensively clarifies managerial decision-making processes related to the implementation of the WEMS.

Abstract:

In an increasingly uncertain world, water is constant and central to most things: the economy, energy, transport, agriculture, health, leisure, wellbeing, social and cultural life. The 7th Water Efficiency (WATEF) Conference 2022 was, for the first time, held outside Europe in the Caribbean, at the Faculty of Engineering, The University of the West Indies, Saint Augustine Campus, Trinidad and Tobago on 14th-16th December, 2022. Many challenges reflect the changing climate, increasingly unpredictable weather, and the efforts towards sustainable development necessary for social equity and economic growth. Proactive partnerships and collaborations across civil society is necessary to succeed in this effort. A conference on water efficiency and resilience is justified in the face of these challenges and during an energy, cost-of-living, food, and other crises. The WATEF-2022 Conference’s theme was “Water Resources Resilience for Small Island Developing States (SIDS)”. Trinidad and Tobago has a relatively high reliable water infrastructure (including desalination plants) for its population but in recent times water resources have been impacted by unforeseen climate change events. This twin-island republic was best suited for this conference, geographically and technically. Parallel with invited keynotes and feature speeches, technical presentations and panel discussions were made addressing various topics and areas associated with the conference’s theme. This paper contains a total of 28 abstracts excerpted from the Conference proceedings that address towards collaborative solutions to the water and resilience challenges faced globally and experienced more intensely by SIDS.

Abstract:

Pearl millet (Pennisitum glaucum L.) is a warm season C4 grass well adapted to semiarid climates where concerns over scarce and depleting water resources continually prompt the search for water efficient crop management to improve water use efficiency (WUE). A two-year study was conducted in the Southern Great Plains, USA, semi-arid region, to determine optimum levels of irrigation, row spacing, and tillage to maximize WUE and maintain forage production in pearl millet. Pearl millet was planted in a strip-split-plot factorial design at two row widths, 76 and 19 cm, in tilled and no-till soil under three irrigation levels (high, moderate, and limited). The results were consistent between production years. Both WUE and forage yield were impacted by tillage; however, irrigation level had the greatest effect on forage production. Row spacing had no effect on either WUE or forage yield. The pearl millet water use-yield production function was y = 6.68 × x (mm) − 837 kg ha−1; however, a low coefficient of determination (r2 = 0.31) suggests that factors other than water use (WU), such as a low leaf area index (LAI), had greater influence on dry matter (DM) production. Highest WUE (6.13 Mg ha−1 mm−1) was achieved in tilled soil due to greater LAI and DM production than in no-till.

Abstract:

The article provides an analytical review of the achieved crop yields under irrigation in experimental and production conditions. For today, the best production experience in the use of irrigated land indicates that, subject to all agrotechnical requirements, the yield of early grain crops reaches 8-10 t / ha, corn - 10-14 t / ha, oilseeds - 4-6 t / ha, vegetable crops - over 60 t / ha, which is about 90% of their productivity achieved in the experiments of scientific institutions. The comparative assessment of grain production in different climatic zones of Ukraine for the period of the most intense climatic change shows that over the past thirty years, the share of grain production in the Steppe zone has decreased from 45 to 35% of the total in Ukraine. The analysis of service cost for the transportation of water for irrigation in the southern regions of Ukraine is given. It was revealed that, despite a unified standard method for calculating the cost of water transportation, its price varies significantly by operational units of the State Agency for Water Resources of Ukraine. The main factors of fluctuations in the cost and fees for the transportation services of water for irrigation are the budgetary funding level of operating organizations, providing these services, the number of water transfers, the volume of actual irrigation on irrigated lands, the share of irrigated areas in the service area. The economic assessment of irrigation efficiency when having different water and other technological costs, taking into account the depreciation of capital investments, indicates that having a water price of 4,0-5,0 UAH/m3, the gross profit from growing the most profitable field crops is 35-40 % higher than the efficiency in rainfed agriculture. At the cost of water is 3,0-3,5 UAH/m3 and the use of the production capacity of the inter-farm irrigation network by 60-70%, financial prerequisites will be created for the effective operation of these networks.

The holistic approach to water saving projects has allowed a better understanding of the actual pay back on projects. In addition to this work, the Smart Water Fund commissioned a review of industrial ecology opportunities for Melbourne. This project was completed in 2008. The paper outlines the project outcomes and how it has been embedded in the cleaner production program at South East Water.
