Decentralised Wastewater Treatment Systems (DEWATS) and Sanitation in Developing Countries


Book Description

In many countries, a rapidly upcoming demand for decentralised wastewater treatment systems (DEWATS) and a demand for efficient community-based sanitation (CBS) can be observed. DEWATS is designed to be an element of a comprehensive strategy for city-wide planning and sustainable infrastructure development. In this book, not only are the technical requirements for the efficient treatment of wastewater at a given location explained, but the specific socio-economic conditions and steps for community action planning are also taken into consideration.







The United Nations world water development report, 2017


Book Description

The United Nations World Water Assessment Programme (WWAP) is hosted and led by UNESCO. WWAP brings together the work of 31 UN-Water Members and 38 Partners to publish The United Nations World Water Development Report, (WWDR) series. The annual World Water Development Reports focus on strategic water issues. UN-Water Members and Partners, all experts in their respective fields, contribute the latest findings on a specific theme. The 2017 edition of the World Water Development Report focuses on 'Wastewater' and seeks to inform decision-makers, inside and outside the water community, about the importance of managing wastewater as an undervalued and sustainable source of water, energy, nutrients and other recoverable by-products, rather than something to be disposed of or a nuisance to be ignored. The report's title - Wastewater: The Untapped Resource - reflects the critical role that wastewater is poised to play in the context of a circular economy, whereby economic development is balanced with the protection of natural resources and environmental sustainability, and where a cleaner and more sustainable economy has a positive effect on the water quality. Improved wastewater management is not only critical to achieving the Sustainable Development Goal on clean water and sanitation (SDG 6), but also to other goals of the 2030 Agenda for Sustainable Development.




Efficient Management of Wastewater


Book Description

Water reuse management is one of the challenges all water scarce countries have to deal with in the coming decades. The present book highlights non-conventional solutions within the field of wastewater treatment and reuse predominantly for professionals and decision makers. It focuses on technologies which are reliable, sustainable, low cost and suitable for rural and sub urban areas. In addition, particularly innovative on-site concepts are presented.




The Future of Water in African Cities


Book Description

Coping with increasing water demand of rapidly-growing cities in Sub-Saharan Africa will require new and innovative planning and management solutions. This book presents Integrated Urban Water Management, an innovative and holistic approach for all components of the urban water cycle to better adapt to current and future urban water challenges.

The United Nations world water development report 2019


Book Description

Access to water and sanitation is internationally recognized human right. Yet more than t wo billion people lack even the most basic of services. The latest United Nations World Water Development Report, Leaving No One Behind, explores the symptoms of exclusion and investigates ways to overcome inequalities.




Faecal Sludge and Septage Treatment


Book Description

Faecal Sludge and Septage Treatment confronts the urgent need to treat increasing volumes of faecal sludge and septage in the rapidly expanding towns and cities of the global south. It discusses the urban contexts that influence treatment requirements and the overall septage treatment processes.




Regenerative Sanitation


Book Description

This book proposes Regenerative Sanitation as the next era of sanitation management and attempts to provide a foundation for the study of sanitation on the premise that sanitation is a complex and dynamic system that comprises of social-ecological, technological and resource systems. The preconception is that sanitation will deliver maximal benefits to society only when there exists a cyclical integration of the three subsystems to enable appropriate linkages between ‘technological design’ and the ‘delivery platform’ so as to achieve optimal and sustained sani-solutions. It also calls for the rethinking of sanitation to change the narrative towards more progressive trajectories such as resource recovery and reuse rather than just amelioration. It explores the contributions to food security, livelihood support, urban regeneration, rural development and even local economies. A new paradigm, theory and ten principles for ensuring practical and effective sanitation solutions and management is presented. In addition is a unique conceptual framework applicable to both developed and developing countries, and to all stages, processes and cycles of delivering sanitation solutions that could critically evaluate, analyse and provide credible, adequate and appropriate sanitation solutions. All of which culminates in a strategic and practical application platform called ‘Sanitation 4.0’ that advocates for total rejuvenation and comprehensive overhaul with eight key strategic considerations for the implementation. Regenerative Sanitation: A New Paradigm For Sanitation 4.0 is inter and trans- disciplinary and encourages collaboration between engineers, scientists, technologists, social scientists and others to provide effective and practical user-centred solutions. It includes relevant case studies, examples, exercise and future research recommendations. It is written as both a textbook for researchers and students as well as a practitioners’ guide for policymakers and professionals.
