Decentralised Wastewater Treatment Systems (DEWATS) such as disseminated by the Bremen Overseas Research and Development Association (BORDA) are increasingly being recognized by decision makers across the world as an option for service delivery in densely populated low-income areas. This thesis investigates full-scale anaerobic reactors of communal DEWATS implemented in tropical regions in order to consolidate the basis of future design and support monitoring, operation and maintenance procedures. Special focus is laid on the operation of the Anaerobic Baffled Reactor (ABR) as the core technology of DEWATS.
EThekwini Municipality, in common with other municipalities in South Africa, are faced with the increasing challenge of providing housing and infrastructure to the population of the city. The city therefore looked to the DEWATS approach as a possible sanitation solution for future housing developments. The document looks at the technical lessons learnt from the evaluation of the DEWATS process under different operating conditions.
This Global Practice Scan of relevant practices, experiences and lessons from sanitation and other decentralised sectors was conducted to inform and inspire the research team and collaborators. We used a governance framework that is new for the sanitation sector as our lens for the scan, separating day-to-day operational responsibilities from the institutional arrangements that help or hinder successful operation. Four key governance domains emerged: sustaining demand, effective management, sustainable financing, and functioning technology.
This guidebook is addressed to Urban Service Providers or National and local governments as well as to academic institutions, international NGOs or local community-based organizations. The guidebook not only explains technical requirements for efficient treatment of wastewater in locations with a special geographic focus in developing countries. It also includes socio-economic conditions and steps for community action planning.
EVI has been commissioned by Bill & Melinda Gates Foundation for carrying out a technical and financial analysis for opportunities and obstacles associated with various FS to energy processing options. The project's focus is on urban India.
This factsheet emphasises the need for climate change mitigation and adaptation measures in the area of sanitation. In addition, it provides an overview of the possibilities of using sanitation systems for renewable energy production, nutrient recovery and it explains the financial benefits that emission trading can bring.
In 2002, a group of technicians with strong interest in the link between environmental protection and human well-being, started to implement household biogas digesters for sanitation purposes in Maseru/Lesotho. Since then, biogas systems for decentralised wastewater treatment (or Biogas DEWATS) were constructed for individual households especially in urban and peri-urban settlements and at institutions like schools, orphanages, prisons and holiday resorts countrywide. This document gives an overview on the technology as it is implemented in Lesotho.
China plays a leading role in the development and dissemination of household biogas technology. One of these technologies is the 4-in-1 biogas system, which has been promoted and implemented in colder regions of China. A survey on the acceptability of 4-in-1 biogas systems in two townships in Liaoning Province was undertaken in July, 2010. The purpose of the survey was to clarify the status of 4-in-1 biogas systems and to learn more about people’s attitude and behavior towards them.
Anaerobic treatment units as part of an on-site decentralised or semi-decentralised wastewater treatment system are an alternative to centralised wastewater treatment systems due to their energy and soil conditioner production capacity, low-tech components and adaptability. It is also an excellent technology for organic sludge treatment, collected from septic tanks, holding tanks, dry toilets, settlers or from aerobic wastewater treatment systems.
