Taschenbuch. Zustand: Neu. Neuware - Improving and managing universal services of water and sanitation in a holistic manner is critical to achieving the Sustainable Development Goals, and addressing the needs of millions of people around the world. Ensuring access to water services is a key factor in working towards the SDGs, and water service delivery planning can support utilities in improving provision of these services. A service delivery plan identifies the actions required and associated costs for achieving a defined level of water services delivery over a defined period of time. This publications is a guideline or how-to manual on preparing water service delivery plans with a focus on small to medium sized organised water utilities having with approximately 5,000 to over 100,000 connections mainly in areas with limited capacity and resources. The manual is simplified enough to ensure that these utilities are able to move from a situation where they are struggling to deliver water services to where basic service levels in terms of water quality, quantity, accessibility, reliability, affordability, and acceptability are met. Meeting these basic service levels provides a strong foundation for the utility to progressively move up the ladder of delivering improved services.…

Taschenbuch. Zustand: Neu. Neuware - 'Cultural aversion to microbes, healthiness or desire for safe bathing, the applications for water disinfection are varied and the technologies used to achieve this goal are numerous.The authors looked at a simple solution to implement: the use of a reagent called performic acid. Consequently, more than two years of applied research, observations and analyzes were necessary to demonstrate its harmlessness towards the natural environment.The strength of the demonstration lies in the cross-vision of many researchers and scientists from different backgrounds who shared their studies and observations. The strength of this testimony also lies in the diversity of the application cases, including notable and sensitive receiving environments as different as the Seine, the Atlantic Ocean or the Venice lagoon.Through its intentions and results, this work is a step, moving forward the 2030 Agenda for Sustainable Development, particularly SDG 6 ?clean water and sanitation? relying on the lever of SDG 17 ?partnerships for the goals.'Denis Penouel, Deputy CEO in charge of Prospective.…

Taschenbuch. Zustand: Neu. Neuware - The case for investment in water, sanitation and hygiene (WASH) has been convincingly made. WASH is essential for protecting public health, is a human right and investing in it is compelling from a fiscal and economic point of view. While the estimated $114 billion per year of capital investments required to meet universal access to safely managed water and sanitation services by 2030 is often portrayed as a hefty price tag, current best estimates of benefit-to-cost ratios leave little doubt about its value.What is less clear is how to allocate resources efficiently. There is limited evidence on the cost efficiency and cost effectiveness of various policy and implementation choices. The underlying drivers of demand for (new) technologies and solutions are, for example, poorly understood, as is beneficiaries? willingness to pay (WTP), leading to open questions about pricing policies and sustainable business models.This is in contrast to other infrastructure sectors, such as energy and transport, where active literature on the economics and financing of services has been more helpful in defining national and international policy. Our objective with this book is to encourage the WASH sector to follow suit and start to effectively engage and research these issues.At the heart of this book therefore, are chapters which highlight some of the specificities, and challenges of conducting full economic evaluations of WASH interventions, provide a deeper understanding of potential solutions, and present new findings on costs and outcome measures, thereby contributing towards a fuller picture of WASH cost-effectiveness.In Focus ? a book series that showcases the latest accomplishments in water research. Each book focuses on a specialist area with papers from top experts in the field. It aims to be a vehicle for in-depth understanding and inspire further conversations in the sector.…
