Case study on constructed wetlands for a peri-urban housing area. Septic tanks are used to pre-treat the sewage. The pre-treated wastewater is transported through a small-bore sewer system.

In July 2012, a team from RTI International deployed to the Philippines to evaluate four FSM programs with the goal of reporting on best practices and lessons learned. The four cases—Dumaguete City, San Fernando City, Maynilad Water for the west zone of metro Manila, and Manila Water from the east zone of metro Manila—were chosen to highlight their different approaches to implementing FSM.

Within the BMZ (German Federal Ministry for Economic Cooperation and Development) financed project on “Advice on the Decentralisation of the Water and Sewerage Sector in Albania” the GIZ and MPWT (Albanian Ministry of Public Works and Transport) initiated the pilot constructed wetland to raise awareness for low cost, appropriate and decentralised sanitation technologies in line with EU standards. It is aimed to be used as a model treatment plant by the main actors of the sector for training, demonstration, research and replication in peri-urban and rural areas of Albania.

The underlying philosophy of phytoremediation research at UFZ (Centre for Environmental Research) is to exploit and to optimise the processes in the rhizosphere. Low-cost, simple systems will be developed to control the environmental problems of different countries in several continents irrespective of their industrial capabilities and conditions – without losing sight of the key principle of cleaning up polluted environmental media in a natural, ecologically balanced way.

Hybrid constructed wetland systems have recently been used to treat wastewaters where high demand for removal of ammonia is required. However, these systems have not been used too often for small onsite treatment systems. This study describes an experimental system for mechanically pre-treated wastewater.

Over the past three decades, anthropogenic emissions of chemical compounds into the atmosphere have caused many environmental and health problems. Some chemicals, such as chlorofluorocarbons (CFCs), are produced deliberately and end up in the atmosphere by accident from equipment or goods. Others, such as sulphur dioxide (SO2) and carbon monoxide (CO), are unavoidable by-products of burning fossil fuels. Urban air pollution, acid rain, contamination by toxic chemicals (some of them persistent and transported over long distances), depletion of the stratospheric ozone layer and changes in the global climatic system are all important environmental threats to ecosystems and human wellbeing.

Use of ion exchange processes as in the BioCon-process, make it possible to recover the phosphate as phosphoric acid, which is produced from apatite ore, thus preserving the limited apatite resources and the resources, mainly sulphur, needed for producing phosphoric acid from apatite.

The project aimed at providing safe water supply and sanitation to the population resettled – after floods – in the less flood-prone Guara-Guara region in the Sofala Province, Mozambique. Since the area is characterised by high groundwater tables, so called “ventilated double vault urine diversion dehydration toilets” (UDDTs) were implemented to not contaminate the groundwater, and thus not threaten public health (unlike pit latrines).

This manual discusses the capabilities of constructed wetlands, a functional design approach, and the management requirements to achieve the designed purpose. The manual also attempts to put the proper perspective on the appropriate use, design and performance of constructed wetlands. Furthermore, the document contains two case studies.

This case study presents a post-rehabilitation project in Bangladesh after cyclone Sidr in 2007, which included provision of 100 twin vault UDDTs in rural villages. The three main challenges were finding an adequate place on the compound for the UDDTs, the use of UDDTs e.g. daily practices and maintenance, and the reuse of dried excreta.

How important is sanitation during a humanitarian crisis? Why is it important to explore ecological and sustainable sanitation? Groupe URD looks at the case of Eastern Chad, an example of a major long-term crisis. From an acute emergency in 2003, the crisis has gone through a number of phases. The appropriateness of aid mechanisms is currently being questioned, with a particular focus on sanitation. Sustainable sanitation can help to improve the quality of life of refugees and IDPs as well as local populations. From this perspective, what lessons from Eastern Chad could be useful in other contexts?
