- Re: Nice and quick overview about constructed wetland's historical developments, by David AUSTIN, USA - by: F H Mughal December 21, 2014That is a nice brief publication on wetlands' history. I think, USEPA has been instrumental in the use of wetlands. The attached publication, a joint publication of National Oceanic and Atmospheric Administration, Environmental Protection Agency,Army Corps of Engineers, Fish and Wildlife Service, and Natural Resources Conservation Service, is a guide on […]
- Re: Pathogen concentration in untreated fecal sludge - by: SusannahSoilet December 21, 2014I wonder if we need to take a step back from 'counting pathogens' and look at the 'overall transmissibility and outcome of exposure' to these biological entities. For a pathogen/parasite to successfully infect a new host through fecal sludge, it must surmount several steps: 1: gain contact 2: retain infectivity - i.e. have enough vitality […]
- Re: Closed loop recycling of flush water through ABR and Constructed Wetland? - by: canaday December 21, 2014Dear Dennis and Detlef, Dennis, the idea would be to treat this blackwater just as well as if we were dumping it into the environment, only never dump it into the environment, so maybe somewhere between 0 and 200 fecal coliform bacteria per 100 ml. It would be key to eliminate any smell or color, so users do not enough notice the difference. Detlef, thanks f […]
- Re: Pathogen destruction in biogas plant vs ABR (Anaerobic Baffled Reactor) - by: KeithBell December 20, 2014Other than clostridium botulinum, another pathogenic clostridia of concern in biogas is clostridium perfringens. High concentration of Clostridium perfringens found at 45 days reveals a risk to use the digested slurry on the arable land. Some Clostridium spp. may cause infection in animals e.g. blackleg (Clostridium chauveoi), malignant (Clostridium septicum […]

In Sub-Saharan Africa sanitation needs of the majority of the urban population are met by onsite sanitation technologies such as pit latrines. As part of the SPLASH sanitation research programme the FaME (Faecal Management Enterprises) and U-ACT Project researched innovative solutions to increase access to sustainable sanitation services. Building on this research Sandec/Eawag has recently started the SEEK Project (Sludge to Energy Enterprises) researching co-processing of faecal sludge and other urban waste streams into fuel pellets and with these electricity through gasification.

The first book dedicated to Faecal Sludge Management (FSM) has been published recently by IWA Publishing. The book ‘Faecal Sludge Management, systems approach for implementation and operation‘ as well as the individual chapters can be downloaded from this page. Damir Brdjanovic, Professor of Sanitary Engineering and Mariska Ronteltap, Senior Lecturer of Sanitary Engineering at UNESCO-IHE have edited the book, together with Dr. Linda Strande, director of the Excreta and Wastewater Management group at EAWAG (the Swiss Federal Institute of Aquatic Science and Technology). The book is funded by the Bill & Melinda Gates Foundation and the Swiss Agency for Development and Cooperation.
The appropriate and adequate management of faecal sludge deriving from onsite technologies is imperative for the protection of human and environmental health. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of this rapidly evolving field, and presents an integrated approach that includes technology, management and planning. It addresses the planning and organization of the entire faecal sludge management service chain, from the collection and transport of sludge and treatment options, to the final enduse or disposal of treated sludge. In addition to providing fundamentals and an overview of technologies, the book goes into details of operational, institutional and financial aspects, and provides guidance on how to plan a city-level faecal sludge management project with the involvement of all the stakeholders.
Despite most residents of African and Asian cities depending on non-sewered sanitation, only a handful of sanitation authorities have addressed the management of faecal sludge from these systems. This Practice Note describes the launch of a faecal sludge management (FSM) service in the peri-urban area of Kanyama, in Zambia.

Issue 153 | July 11, 2014 | Focus on Fecal Sludge Management
This issue focuses on studies, reports, and other materials that have been published so far in 2014 on fecal sludge management (FSM). Included is a just-published and comprehensive guide on planning and organizing the entire fecal sludge management service chain. A WASTE report evaluates FSM methods in emergency situations, and a Water and Sanitation Program report examines FSM in 12 cities.
3rd International Faecal Sludge Management Conference, Jan 18-22, 2015, Hanoi, Vietnam. (3rd Conference Link) | (2nd Conference Presentations)
Building on the success of the two previous International FSM Conferences in Durban (2011 and 2012), FSM3 will bring together world-class research and science and donors, cities, utilities, investors, consultants, governments, service providers, and industries with the aim of fostering an effective dialogue on solving the problem of dealing with human waste.

Emergency Sanitation: Faecal Sludge Treatment, 2014. J Spit, WASTE. (Link)
This research aims to expand the knowledge of possible simple fecal sludge treatment technologies that could be rapidly deployed in the event of an emergency and are effective under challenging physical conditions such as unstable soils, high water tables, and flood-prone areas. Three fecal sludge sanitization methods—lactic acid fermentation, urea treatment, and hydrated lime treatment—were investigated by undertaking small scale field trials with pit latrine sludge in Blantyre, Malawi.
Facilitation Manual: Sanitation Entrepreneur Training, 2014. Water and Sanitation Program (WSP). (Link)
A WSP team felt there was a growing need for a standard reference for implementing sanitation entrepreneur training and developed a training program and guide that could be replicated and carried out independently by interested stakeholders.
The iDE Sanitation Marketing Scale Up (SMSU) project operates in seven Cambodian provinces. It started with a pilot project in 2009 and scaling-up began in September 2011. So far total latrine sales including the pilot is 118,000.
The average latrine coverage in the seven provinces where the project is taking place inceased by 11% to 40% over the two years since scale up began. Coverage for the poor increased 6% overall. In Kandal province alone, 18% of project-linked sales went to poor households, nearly doubling poor coverage in that province from 15% to 29%.
The three-year SMSU project is funded by the Bill & Melinda Gates Foundation and the Stone Family Foundation, and technically supported by the Water and Sanitation Program (WSP) of the World Bank. The project is supported by the Ministry of Rural Development.
For every latrine sold through a small business trained by iDE, another latrine is sold through a non-connected business, creating a ripple effect. The average latrine sells for US$ 41.50.
SNV has produced a short video on the harsh reality of current urban sanitation practices in Bangladesh. Of course they want to change this. That is at least the intention of SNV’s recently launched “Modernising urban sanitation in Southern Bangladesh” project focussing on market-based solutions.
In 2014 and 2015 UNESCO-IHE is offering a 3-week course on Faecal Sludge Management.
This course is designed for sanitary, civil / wastewater and environmental engineers. It will introduce findings from the ongoing research from the Pro-Poor Sanitation Innovations project funded by the Gates Foundation.
