Water Supply And Sanitation

Drinking-water supply and sanitation services are essential for human health, but their technologies and management systems are potentially vulnerable to climate change. An assessment was made of the resilience of water supply and sanitation systems against forecast climate changes by 2020 and 2030. The results showed very few technologies are resilient to climate change and the sustainability of the current progress towards the Millennium Development Goals (MDGs) may be significantly undermined. Management approaches are more important than technology in building resilience for water supply, but the reverse is true for sanitation. Whilst climate change represents a significant threat to sustainable drinking-water and sanitation services, through no-regrets actions and using opportunities to increase service quality, climate change may be a driver for improvements that have been insufficiently delivered to date.

This document proposes a methodology for assessing the quality of water distribution service in the context of intermittent supply, based on a comparison of joint results from literature reviews and feedback from drinking water operators who had managed these networks, with standards for defining the quality of drinking water service. The paper begins by reviewing and proposing an analysis of the definition and characterization of intermittent water supply (IWS), highlighting some important findings. The diversity of approaches used to address the issue and the difficulty of defining a precise and detailed history of water supply in the affected systems broadens the spectrum of intermittency characterization and the problems it raises. The underlined results are then used to structure an evaluation framework for the water service and to develop improvement paths defined in the intermittent networks. The resulting framework highlights the means available to water stakeholders to assess their operational and management performance in achieving the improvement objectives defined by the environmental and socio-economic contexts in which the network operates. Practical examples of intermittent system management are collected from water system operators and presented for illustration purposes (Jeddah, Algiers, Port-au-Prince, Amman, Cartagena, Barranquilla, Mexico, Cancun, Saltillo, Mumbai, Delhi, Coimbatore …).

Given that the quality of water supplied to hot water supply systems must meet drinking water requirements, it is also important that the water preparation process is of great importance. The quality of that water is also important in terms of preventing the formation of heat in hot water systems. It is known that the main cause of the formation of water is the presence of calcium and magnesium cations and bicarbonate and sulfate anions in water. The traditional methods for preventing the limescale include the combination of calcium and magnesium cations from the water and replacing them with cations that are not easy to resolve at high temperatures. The quality of water treated by these methods does not meet drinking water requirements. Taking these into account, the Cl-anionizationprocess of drinking water has been developed in high-tech anionite technology. According to this technology, the first water from the city water gridis processed through anionite and activated carbon filters, which are mechanically charged with high anionite. The treated water is then cleaned out of microbes and bacteria through the ultraviolet disinfection equipment and delivered to the operator according to the quality requirements for drinking water. In the chlorine-anionization process, most of the sulfate and bicarbonate anions in water change to chlorine anions and their solidity remains constant. Thus, the density of the limescale-forming anions in the water decreases sharply and it meets the quality indicators of drinking water. High-grade anionite in the filter (8÷12) is regenerated by NaCl solution. The filtration rate of the solution from the anionite is determined depending on the concentration of calcium cations contained in the salt given for regeneration. Regeneration mode is such that the CaCO3 combination does not crumble when the anionite layer is formed. It is known that the temperature of the heated water in the hot water supply system does not exceed (60÷70)°C. In this case, the decomposition of limescale at Hc<2 mg-eq/l (carbonate hardness) is not observed. As carbonate hardness increases to 4 mg/l, the thin layer in the system shows a collapse. The basic element of the proposed technological schemeCl-anionite filter was applied at ADA University in Baku and positive results were obtained. Early observed collapse of pipes has been prevented and the working regime of hot water heaters has improved. A high-performance anionite such as A200EMBCl, which is a major ingredient of the UK's Purelite, and then the Russian-made AB-17-8 high-anionite anions have been used on the device.

Water Supply And Sanitation

The European Water Supply and Sanitation Technology Platform (WSSTP) is an industry driven organisation aiming to strengthen the potential for technological innovation and the competitiveness of the European Water Industry. In response to global challenges and regional demands a strategy has been proposed to ensure safe, secure and sustainable water and sanitation services for the benefit of industry, the society and the environment. Integrated Water Resources Management is used as a guiding principle. Water supply, wastewater treatment (sanitation), river basin management and concerns of regulators, financing institutions and the civil society are the key elements of a system to be sustainably managed. Decision makers of the private and the public sector are to understand that investment in research, technology development and implementation of innovation is an important element in the process of securing economic prosperity, social stability and functioning of the ecological systems which we as human beings are a part of. A hierarchic, practice oriented structure is proposed to organize and govern research and technology development in Europe. Research will be organized within the framework of thematically designed pilot programmes containing a distinct number of implementation cases to execute close-to-reality research.

Water Supply And Sanitation

A green economy specifically considers the welfare of the environment and is closely aligned with sustainable development—in both, the use of natural resources should be less than their natural production. In this article, the concept of a green economy is discussed from the viewpoint of water services, a crucial part of a sustainable society, with the objective of enhancing knowledge about sustainable and resilient water services that will meet society’s future demands. Drawing from a literature review and a stakeholder workshop attended by 68 experts, it seeks to answer three research questions: (a) What are appropriate and sustainable urban water supply and sanitation policies for a society that is adopting the basic principles of a green economy? (b) What should be the role of water supply and sanitation in a green and circular economy and what are the current challenges to meeting this objective? and (c) What actions are needed in the Finnish water and sanitation services (WSS) sector to effectively meet the requirements of a green and circular economy? The results are applied to the specific case of Finland, and recommendations and conclusions for the Finnish society and its water services are presented.
