Standard For Decentralised Faecal Sludge Treatment In Developing Countries. Water Online, November 8, 2016.
TÜV SÜD has started developing a private technical standard for decentralized treatment plants. The aim is to promote innovations for safe and environmentally friendly sanitation in developing countries. The work is funded by a grant from the Bill & Melinda Gates Foundation.
“Our experience proves the value of standards in promoting new technologies”, says Dr Andreas Hauser, Director of Water Services at TÜV SÜD. “Establishing common guidelines is a key step towards fostering next-generation faecal sludge treatment plants as well as engaging commercial interests”. The standard will refer to technologies that can convert waste into beneficial outputs, like electricity, biomass, water for irrigation and ash – in accordance with the resource-oriented sanitation approach.
They are operated on a commercial basis and serve up to 10.000-100.000 people improving hygiene, living conditions and creating economic opportunities. For them to become accepted and adopted essential criteria need to be met concerning for example functional safety, treatment performance, occupational health or emission values.
The private technical standard is to define these criteria. It is a follow-on project within the Gates Foundation’s Omni-Processor program. Beginning in November 2015 TÜV SÜD has been examining and evaluating the various requirements and possibly relevant standards for decentralized, community scale faecal sludge treatment solutions.
Developing a standard now takes this work to a new level. Dr Andreas Hauser: “A private technical standard for decentralized faecal sludge treatment plants will benefit the entire value chain towards a resource-oriented sanitation approach.”

Targeting urban sanitation – looking behind aggregated city-level data. World Bank Water Blog, Oct 31, 2016.
In our previous blogs – Fecal Sludge Management: the invisible elephant in urban sanitation, 5 lessons to manage fecal sludge better, and A tale of two cities: how cities can improve fecal sludge management – we outlined the neglect of Fecal Sludge Management (FSM) and presented new tools for diagnosing urban sanitation challenges and how they can be used.
Today, on World Cities Day, we are looking more deeply into a city – Lima, Peru, to shed light on how cities around the world can meet opportunities and address challenges of urbanization including providing improved sanitation for a rapidly growing number of urban residents.
The city-wide sanitation picture
To apply one of the better known FSM tools – the fecal waste flow diagram (SFD) – we use data to provide a city-wide picture of sanitation services at the household level, and how the fecal waste flows through the ‘sanitation service chain’: removal and conveyance from the household containment or WC, to treatment and final disposal or reuse.
SFDs provide an easy to understand and visual representation of where fecal waste and the associated pathogens and pollution end up. This enables decision-makers and technical staff to understand and discuss the priority sanitation issues requiring attention in their city.

4th International Faecal Sludge Management Conference, 19 – 22 February 2017, Chennai, India
Worldwide, 2.7 billion people rely on onsite sanitation. Yet, there is still typically no management system in place to deal with the resulting faecal sludge (e.g. septage and pit latrine sludge). The result is that the waste typically ends up being dumped directly into the urban environment, with significant health and environmental implications. Creating faecal sludge management (FSM) infrastructure and public services that work for everyone, and keep faecal sludge out of the environment is a major challenge for achieving universal sanitation access.
To address this challenge, a global platform for discussion of FSM was created in 2011 by leading global sector organizations. The aim was to share and brainstorm potential solutions, to formulate policy recommendations that promote best practices, and to identify lessons learned in how to make FSM an integral part of sanitation service delivery. Building on the success of the first three International FSM Conferences in Hanoi (2015) and in Durban (2011& 2012), FSM4 aims to bring together professionals working in the sector, including utilities, service providers, cities, governments, academics, scientists, consultants, donors and industries, to support the global initiative of disseminating sustainable solutions for FSM.
FSM4 will be held in Chennai, Tamil Nadu, where the State Government has recently initiated measures to address FSM with regard to policy, regulatory changes, innovative solutions, and pilots. FSM4 will focus on innovative and practical solutions that can be scaled up, including three tracks: research, case studies, and industry & exhibition.

In this blog, we’ll share some lessons learned from the city-specific case studies and analysis to highlight key areas which need to be addressed if the non-networked sanitation services on which so many citizens rely are to be effectively managed.
Lesson 1: Fecal sludge management must be included in national policy and legislation
On-site sanitation is often the only sanitation option for poor households, and may account for the majority of all sanitation, in many middle income and poor countries. However, the construction and servicing of on-site facilities is typically left to the unregulated informal sector.
There can even be legal barriers to developing on-site sanitation, although integrated urban water management may identify the provision of clean piped water, with systematic FSM, as a cheaper, more effective solution than city-wide sewerage access. The formal recognition and regulation of on-site sanitation and FSM is therefore critical.

Fecal sludge management is the elephant in the room, but we have developed tools to help | Source: World Bank Water Blog, July 6, 2016 |
Recently developed Fecal Sludge Management tools to help address this important, but often-ignored, urban sanitation issue.
In the rapidly expanding cities of the developing world, sanitation is of ever growing importance – more people mean more exposure to fecal pollution, and therefore a greater risk to public health. The widely accepted solution, taught to sanitary engineers worldwide, is to flush human waste into sewers which take it to large, centralized treatment facilities.

This requires expensive infrastructure, a plentiful water supply, skilled operators and a substantial and reliable stream of operating funds. This means that in most low- and middle-income country cities, the sewerage service is only available to a small and decreasing proportion of the population, as investments cannot keep up with the explosive urban growth.

Market-based Approaches to Sanitation, 2016. PSI.
Market-based approaches can be applied to deliver a number of products (such as household, shared, or public toilets, using various designs and materials), services (like installation or waste removal and treatment) and forms of service delivery (free or pay-for-use).
This review focuses on models for household pit latrine construction and fecal sludge management.
