This manual and the free downloadable costing tool is the outcome of a project identified by the Water, Sanitation and Health Programme (WSH) of the World Health Organization (WHO) faced with the challenge of costing options for improved access, both to safe drinking water and to adequate sanitation. Although limited in scope to the process of costing safe water supply technologies, a proper use of this material lies within a larger setting considering the cultural, environmental, institutional, political and social conditions that should be used by policy decision makers in developing countries to promote sustainable development strategies. Costing Improved Water Supply Systems for Low-income Communities provides practical guidance to facilitate and standardize the implementation of social life-cycle costing to "e;improved"e; drinking-water supply technologies. These technologies have been defined by the WHO/UNICEF Joint Monitoring Programme for Water Supply and Sanitation, as those that, by the nature of its construction, adequately protect the source of water from outside contamination, in particular with faecal matter. The conceptual framework used has also been conceived to be applied to costing improved sanitation options.To facilitate the application of the costing method to actual projects, a basic tool was developed using Microsoft Excel, which is called a water supply costing processor. It enables a user-friendly implementation of all the tasks involved in a social life-cycle costing process and provides both the detailed and the consolidated cost figures that are needed by decision-makers. The scope and the limits of the costing method in a real setting was assessed through field tests designed and performed by local practitioners in selected countries. These tests were carried out in Peru and in six countries in the WHO regions of South-East Asia and the Western Pacific. They identified practical issues in using the manual and the water supply costing processor and provided practical recommendations.

Source Separation and Decentralization for Wastewater Management sets up a comprehensive view of the resources involved in urban water management and the potential of source separation and decentralisation to provide viable alternatives to sewer-based urban water management.

The overall objective of Reservoir Eutrophication: Preventive Management is to present the environmental and anthropogenic factors associated with the process of eutrophication and algal blooms in the Rio Verde reservoir and propose lake use and management technologies in order to minimize the problem. Eutrophication process in Rio Verde reservoir with the occurrence of intense algal blooms is a consequence of the interconnection of different climatological, hydrological, morphological, physico-chemical and biological factors, which occur not only in the watershed but also in the reservoir. Reservoir Eutrophication: Preventive Management compiles the information gathered from the development of a broad research program in Rio Verde watershed, from 2008 until 2010. Rio Verde reservoir, which was built in 1976, is located in the Metropolitan Region of Curitiba, capital of the state of Paran in South Brazil. This reservoir is mainly used for supplying water to one of PETROBRAS Refinery. However, the reservoir is to be used for supplying drinking water to the population and that is why better understanding this system dynamics is a great concern. The book is the result of an interdisciplinary research program, which has involved more than 150 researchers, with the aim of defining a watershed management preventive system in order to prevent eutrophication processes. This way, the book combines academic rigor with practical applicability and is of interest for both researchers and technologists working in watershed management.Reservoir Eutrophication: Preventive Management is of interest to researchers and technologists that wish to examine specific characteristics of tropical climates. It is of specific interest to developing countries and for researchers interested in knowing the developed methodology adapted for temperate conditions.

This study increases our current understanding on the degradation/ageing mechanisms occurring on porous membranes used in the water and wastewater industries. Accelerated membrane degradation was obtained through both static and consecutive ageing protocols on the pilot-scale, and a range of carefully selected characterisation and analytical techniques was used to characterise the nascent changes faced by the membrane material. The report covers four interrelated sections:Critical assessment of characterisation techniquesStatic accelerated ageingConsecutive accelerated ageingConsecutive ageing of industrially-aged membranes.This final report summarises the aims, objectives, outcomes and limitations of the individual work packages, along with some recommendations for future work.This book is co-published with Water Research Australia.

Helminths: Handbook for Identification and Counting of ParasiticHelminth Eggs in Urban Wastewater is the result of several studies that the public entity for sanitation and wastewater treatment in Murcia Region (ESAMUR), has undertaken regarding the presence of helminth eggs in both urban wastewater and reclaimed water, and their behavior in the Waste Water Treatment Plant (WWTP) processes. The handbook is a useful tool for anyone who is involved in preserving water quality. The identification of parasitic helminth eggs has been simplified with an easy identification key and specific identifying sheets in order to achieve the highest standards within this indicative parameter in water quality. The treatment and disinfection of urban waste water, before its release into the river system or re-use for agricultural or industrial purposes, has been one of the greatest advances within the field of health. The control and study of possible pathogenic parasites that exist in water is an important aspect of the work undertaken at the Waste Water Treatment Plant (WWTP), to guarantee water quality and its safety for release into the river system or for re-use as regenerated water. This handbook has been produced as a result of the information gathered by ESAMUR (Regional Entity for Sanitation and Wastewater Treatment in Murcia Region) and can be used for teaching and as a useful reference source when preserving water quality. Helminths: Handbook for Identification and Counting of ParasiticHelminth Eggs in Urban Wastewater is a valuable handbook for managers of Wastewater Treatment Plants (WWTP), university teachers, laboratory managers, qualified operators, responsible for the reuse of reclaimed water, and general staff involved in related wastewater treatment processes.Author: Carlos Lardin Mifsut, ESAMUR, Murcia, Spain and Silveria Pacheco Ballarin, TCNICA Y PROYECTOS S.A., Murcia, Spain

Advanced wastewater treatment processes and novel technologies are adopted to improve nutrient removal from wastewater so as to meet stringent discharge standards. Municipal wastewater treatment plants are one of the major contributors to the increase in the global greenhouse gas (GHG) emissions and therefore it is necessary to carry out intensive studies on quantification, assessment and characterization of GHG emissions in wastewater treatment plants, on the life cycle assessment from GHG emission prospective, and on the GHG mitigation strategies. Greenhouse Gas Emission and Mitigation in Municipal Wastewater Treatment Plants summarises the recent development in studies of greenhouse gases' (CH4 and N2O) generation and emission in municipal wastewater treatment plants. It introduces the concepts of direct emission and indirect emission, and the mechanisms of GHG generations in wastewater treatment plants' processing units. The book explicitly describes the techniques used to quantify direct GHG emissions in wastewater treatment plants and the protocol used by the Intergovernmental Panel on Climate Change (IPCC) to estimate GHG emission due to wastewater treatment in the national GHG inventory. Finally, the book explains the life cycle assessment (LCA) methodology on GHG emissions in consideration of the energy and chemical usage in municipal wastewater treatment plants. In addition, the strategies to mitigate GHG emissions are discussed. The book provides an overview for researchers, students, water professionals and policy makers on GHG emission and mitigation in municipal wastewater treatment plants and industrial wastewater treatment processes. It is a valuable resource for undergraduate and postgraduate students in the water, climate, and energy areas; for researchers in the relevant areas; and for professional reference by water professionals, government policy makers, and research institutes.
