The commercial success of electro‐deposition of aqueous coating is mainly concerned with the development of water‐soluble film forming polymers. The field of these water‐soluble polymer systems for surface coating application is growing rapidly and expanding vigorously and they are destined to play a leading role in the near future. This may be mainly attributed to regulations on emissions, environment and ecology. In doing so, the electrodeposition technique offers a remarkable assistance to these systems at comparatively low cost, low energy requirement and high utilization efficiency. Research workers have done work on water‐soluble alkyds, epoxies and acrylics.

The acute shortage coupled with tremendous increase in cost of various solvents used by paint industry and pollution becoming a serious concern has resulted in intensive study of water‐borne coatings. Water‐borne coatings ideally meet the needs for coating systems which do not cause atmospheric pollutions and at the same time help in conservation of precious and renewable petroleum resources. Many research workers have developed water‐soluble epoxies, alkyds and acrylics to make water‐based surface coatings.

The deciding factor for operating a governmental project either as an independent, self-supporting municipal enterprise insulated from political influence or as a special revenue fund financed by tax levies is whether the amount of revenue generated covers the operating costs of the project. Cost allocation issues play an important role in this decision since the development of an acceptable user charge requires calculations of the full-cost per unit of service. If not properly understood and applied, these issues can produce unfair rates, which in turn may lead to wars between the city government and the communities it serves.

To understand the role of cost allocation in developing fair rates for a municipal enterprise's services, this article selects the most common public unity, the municipal water and sewer services, in particular, the Detroit Water and Sewer Department (DWSD). DWSD is one of the largest municipal enterprises in the United States and many of its pricing practices are typical of those followed by many cities in the United States. After presenting and illustrating the current DWSD's cost allocation and pricing procedures to highlight the unfair pricing incidents, the article proposes a modification to the current system that avoids these unfair pricing issues.

Water soluble epoxy resins were prepared from epoxy resin, linseed fatty acids, maleic anhydride, trimellitic anhydride, maleinised dehydrated castor oil and maleopimaric acid. Pigmented coating compositions for anodic electrodepositions were prepared from water soluble epoxy resins using red oxide of iron and zinc phosphate as pigment. The electrodeposition parameters such as voltage, time, solid content and pH value were optimised. The mechanical and chemical film properties of different electrocoating compositions were studied.

The aim of this paper is to review the issues surrounding water security in terms of quantity and quality and its impact on food availability.

The research involved an examination and evaluation of existing literature so that the key elements of a water security policy model could be determined.

Water demand and availability is multifaceted and the degree of water security can be determined at a personal, national or international level. One of the key drivers of water security is the current and continued ability of water resources to meet the often conflicting needs of domestic supply, food production and amenity uses, including the requirement to irrigate food production areas in order to improve food yields and feed the growing global human population and mitigate the impact of any environmental change.

This paper provides an overview of the subject of water security and therefore will be of value to policy makers, academics or those developing environmental risk management strategies for organisations within the food supply chain.

This paper's main objective is to focus on the water-harvesting ability of plants and try to implement a solution-based method to outline a plant-inspired design framework.

The current paper aims to provide a step-by-step approach to the biological-inspired design by looking deeply at plants' mechanisms and features to harvest water and conduct a method to learn them in an organized way.

In addition to the proposed framework, the fundamental water-harvesting principles of plants including increasing condensation, reducing transpiration and facilitating transportation have been extracted by investigating several adaptable plants. The relevant factors related to each of these three principles are introduced and can potentially ease the process of bio-inspiration as it contributes to the findability and understandability of a particular biologic strategy. As a result, this framework can be used to the formation of novel designs in different disciplines. In this process, the development of an architectural design concept is presented as an example.

The current global issue about the shortage of water leads researchers to learn adaptability from nature and increase the demands of using bio-inspired strategies. The novelty of this study is to introduce a water-harvesting design path, which has been presented using a four-step-plant-to-design process. Learning from plants' water-harvesting strategies will contribute to efficiency in different disciplines. The findings of this study have important implications for developing bio-inspired water-harvesting materials and systems. Moreover, the findings add substantially to the understanding of water-harvesting architecture and play an important role in bridging the gap between theory and practice.

Water‐related diseases are a human tragedy, resulting in millions of deaths each year, preventing millions more from leading healthy lives, and undermining development efforts by burdening the society with substantial socio‐economic costs. This problem is of great significance in developing countries, where polluted water, water shortages, and unsanitary living conditions prevail. This paper presents a case study on a health‐based socio‐economic assessment of drinking water quality in Lebanon, based on relevant valuation approaches and available country‐specific data. The assessment revealed that the potential health and economic benefits due to water and sanitation improvements can be significant (0.15‐3.35 percent of GDP).

Undoubtedly, saving the environment and avoiding environmental damage is one of the major challenges facing any government. The purpose of this paper is to add to the accumulative knowledge in the field through investigating the different factors affecting the adoption of newly developed water filters by Egyptian farmers to reduce the massive air pollution resulting from burning rice straw. Such investigation will help in achieving a deep and reflective understanding of current adoption practises by Egyptian farmers.

To understand the different factors that might have an impact on the adoption of newly developed water filters by Egyptians, a survey research strategy as well as a focus groups mechanism were conducted employing triangulation methodology in which quantitative and qualitative data were collected based on a post-positives approach. This quantitative study was performed in five local councils in Al-Sharqiyah Governorate, one of the biggest governorates in rice production in Egypt, based on a questionnaire built on some parameters related to Egyptian farmers’ perceptions of clean water. Statistical analysis was performed using Statistical Package for the Social Sciences to analyse the collected data and evaluate the ability to promote the newly developed filters.

The findings indicated that the adoption of water filters by Egyptian farmers is affected by two groups of factors, namely personal factors and water-related factors. With regard to this, it was found that age, cost, farmers’ attitudes towards using water filters, farmers’ trust in the water pipes systems, and the usefulness of the filters have a positive impact on water filters adoption by Egyptian farmers. The findings also indicate that water filters adoption by Egyptian farmers has a positive impact on a farmer’s intention to buy a water filter and their intention to share a water filter with others.

The paper will provide great benefits for entrepreneurs, policy makers, practitioners, and researchers though providing a clearer view and deep understanding for the issues related to different factors affecting the adoption of newly developed water filters by Egyptian farmers.

This research adds to the relatively limited empirical research that has been conducted on water management in south Mediterranean counties. Moreover, the findings and results of this study will provide great assistance and benefit to business owners, practitioners and governmental agencies concerned with water management in south Mediterranean countries since it reveals a number of dynamics and potential scenarios that should be taken into consideration.

Presents a survey of water, water pollution and control in China. Water shortage and water pollution are two of the most important environmental problems and factors affecting the development of industry, agriculture and the economy. China has made great efforts to improve environmental quality and has issued a series of important policies and regulations since the 1970s. Water saving and waste water reuse are the most significant measures implemented for solving the water shortage and controlling water pollution. All these policies and measures are playing an important role in alleviating and controlling the extent of water pollution.

The tannery industry impacts strongly on water bodies due to the presence of chemical substances, such as chlorides, sulphates, chromium and other pollutants. This study has been carried out with a view to enhance the environmental compatibility of the Arzignano tannery district (northern Italy) which is the largest in Italy, by improving the quality of the Fratta-Gorzone River. Sediment quality, according to the driving forces-pressure-state-impact-response (DPSIR) scheme, has been developed as a significant impact indicator to be applied at basin level. The purpose of this paper is to discuss the above issues.

Data were produced during institutional monitoring and control activities carried out by ARPAV (Veneto Region Environmental Prevention and Protection Agency) according to official methods. To define the environmental impacts on the river basin, a statistical assessment was performed on water and sediment quality data to establish the degree of correlation for the main pollutants along the river stem.

In the basin considered, sediment quality presents high levels of contamination from heavy metals – in particular chromium (Cr) (III) – as well as organic pollutants. Investigation of the pressure sources revealed that the discharge from the Arzignano tannery district is the main source of Cr (III), according to background studies performed in the same area.

The quality of river sediments must be improved in order to avoid the re-suspension/solubility of pollutants; dredged materials with high polluting substances must be managed with specific precautions in order to safeguard the environment.

The river studied is currently the only significant water body in which sediment monitoring has been performed in the Veneto Region (Italy) since 2002. This study presents issues linked to the characterization of river sediment and the correlation between sediment quality and water pollution and prior and current pressure sources.
