This document aims at guiding how to design biogas stove.
For two decades, solid waste components in World Bank projects have focused on collection of solid wastes, with equipment provided to upgrade operations at existing open dumps. Since early 1990, the private sector has become increasingly being involved in the collection, disposal, and treatment of solid waste and World Bank projects have placed greater priority on implementation of new sanitary landfills. The following guidance provides […]
The purpose of this document is to explain the intent and requirements of the Part 503 rule and to assist owner/operators in determining the extent to which their biosolids management operation is covered. To help clarify the intent of the Part 503 rule! this guidance document sometimes uses terms that do not appear in the rule itself and organizes information differently from the rule. For […]
“Human waste” is a term that has traditionally been used to refer only to human excrements, namely fecal material and urine, which are by-products of the human digestive system. When discarded, these materials are colloquially known as human waste. When recycled for agricultural purposes, however, they’re known by various names, including night soil (when applied raw to fields in Asia) and human manure or humanure. […]
Greening innovation and urban agriculture can bring dignity, empowerment and food sovereignty to refugee communities. Simple technologies and waste recovery make these techniques cost effective and adaptable. Both should be central to designing, implementing and sustaining both refugee camps and overcrowded urban areas. This report examines current and potential use of greening innovation and urban agriculture in refugee camps, cities and rural settlements in four […]
The report summarizes the proceedings of the ILE in Indonesia, provides technical details and input of invited resource experts as well as participants, and expands on the key discussions that made the event such a lively, useful and practical experience for all participants. It is hoped that the report will be an important element in joint global knowledge management for WinS and that it will […]

The report sets out to provide guidelines for the preliminary design of faecal sludge treatment schemes comprising solids-liquid separation and stabilisation ponds. The document is based on the results of collaborative field research conducted by the Ghana Water Research Institute and SANDEC on full and pilot-scale faecal sludge (FS) treatment plants located in Accra, Ghana. Published and unpublished documents relating to the subject were also […]
Daniela Krahl of the German Federal Ministry for Economic Development and Cooperation (BMZ) has said that: “The water strategy of our Ministry is seen as a model because it addresses the spirit of the SDGs in a holistic manner, thus going beyond SDG 6. That is what we need today and that is why I like the excreta flow diagram. It brings people from different […]
The use of a vermifilter containing Eisenia fetida to degrade human faeces in a continuous wet system was explored. This paper aimed to understand the formation of vermicompost within the system, the quality of the effluent produced, and the effect of different bedding matrices. Eight filters were constructed, utilising four different bedding materials: four of these systems were seeded with 400 g of worms (vermifilters) […]
The objective of this study was to determine if composting worms and their cocoons are able to survive in and digest faecal sludge. Eighteen vermifilters with different worm and cocoon densities were set-up, fed with faecal sludge (from portable pour-flush toilets) and ran for 38 days. Samples of the sludge, effluent and vermicompost were analysed for pH, total solids, chemical oxygen demand, faecal coliforms and […]
This manual has been prepared for use by local nongovernmental and community-based organisations (e.g. resident initiatives) and relevant persons in urban local governments. Private organisations or entrepreneurs interested in organic waste recycling may also benefit from this book. It may also help development agencies and other government sectors in planning waste management and composting programmes. It can be used as a basic source of information […]
Based on the Field Report Entitled "Sedimentation Tank Sludge Accumulation Study" Prepared by S.A. Larmie WRI (Dec. 1994).
Nitrogen is one of the principal nutrients found in wastewater. Discharges containing nitrogen can severely damage a water resource and it’s associated ecosystem. As a result, several chemical, physical and biological processes have been used to promote the removal of nitrogen. Nitrification and denitrification are two suggested processes that significantly reduce nitrogen levels in wastewater. This fact sheet will primarily focus on the nitrification process […]
Treatment wetlands are natural treatment technologies that efficiently treat many different types of polluted water. Treatment wetlands are engineered systems designed to optimise processes found in natural environments and are therefore considered environmentally friendly and sustainable options for wastewater treatment. Compared to other wastewater treatment technologies, treatment wetlands have low operation and maintenance (O&M) requirements and are robust in that performance is less susceptible to […]
This manual provides comprehensive technical information about the planning, design, construction and operation of WSPs and CWs for a wide range of applications. To understand and design WSPs and CWs requires the involvement of expertise in a variety of fields, including chemistry, hydrology, soil science, plant biology, natural resources, environmental management, ecology, environmental engineering, surveying, and project management.
The implementation of wastewater treatment plants has been so far a challenge for most countries. Economical resources, political will, institutional strength and cultural background are important elements defining the trajectory of pollution control in many countries. Technological aspects are sometimes mentioned as being one of the reasons hindering further developments. However, as shown in this book, the vast array of available processes for the tretament […]
The present series of books has been produced based on the book "Biological wastewater treatment in warm climate regions", written by the same authors and also published by IWA Publishing. In this version, the books aim at presenting consolidated technology based on worldwide experience available at the international literature. However, it should be recognised that a significant input comes from the Brazilian experience, considering the […]
