Moving Towards ODF Status in Cambodia: iDE Shares Findings in New Tactic Reports

3-2-iDE-Cambodia WASH DIB-PR-07_Photo by Chhom DinatSince the beginning of iDE Cambodia’s sanitation marketing initiative in 2009, we have facilitated the sale of over 325,000 latrines, while sanitation coverage has increased from 23% to over 70% in the provinces where we work. Our latest tactic reports provide new insight into how this expansion of sanitation coverage was achieved:

Reaching Open Defecation Free Status with Grassroots Partnerships

iDE is supporting the further development of a sustainable sanitation ecosystem, to and beyond Open Defecation Free status. Our Cambodia team’s Public Private Partnership Department is facilitating deeper connections between the private sector and government, while generating, sharing, and applying market data to help communities bridge the gap to ODF. 

Reaching the Poorest with Sanitation Through Targeted Subsidies

A recent World Bank report describes several common pitfalls of the delivery of WASH subsidies worldwide, including being pervasive and poorly targeted, non-transparent, expensive for implementers, and distortionary for markets. iDE developed its targeted subsidy model to address each of these issues and help poor household sustainably participate in the Cambodian sanitation market.

Addressing Fecal Sludge Management in Rural Locations

iDE is scaling supply and sales of a new type of Alternating Dual Pit product. Equipped with lime treatment service and a device to indicate when the new pit is filling, this technology allows customers to alternate pits back and forth and empty safely composted waste indefinitely. Guiding businesses deeper into the sanitation market has been a challenge, and in order to more smoothly facilitate this process iDE has increased support for businesses on ways to retain staff, provide adequate protection and equipment, and follow a cleaner, safer installation protocol.


iDE pioneered the market-based approach in sanitation, incorporating private businesses, NGOs, and government stakeholders. In 2003, iDE launched the world’s first market-based sanitation program in Vietnam, and, since then, the model has been successfully replicated across iDE’s global portfolio and by other organizations.

Faeces to fertiliser: innovations to solve the world’s toilets crisis

Faeces to fertiliser: innovations to solve the world’s toilets crisis. SciDev, July 2019.

Speed read

  • Pit latrines still best for regions without sewage systems
  • Improvements include membranes to collect faeces and dry flushes to save water
  • Community buy-in crucial to toilet innovation success

With nearly 1.4 billion people still lacking access to even the most basic toilet, researchers around the world are looking for innovative solutions, writes Inga Vesper.

First, some good news. Since the year 2000, the number of people forced to defecate in the open has fallen by more than half to an estimated 673 million. However, 2 billion people still lack basic sanitation services, with more than 700 million relying on rudimentary holes or pits, a World Health Organization (WHO) report showed last month. scidev

The problem is concentrated on around 60 high-burden countries, mostly in Africa and Asia, where water is scarce and infrastructure — such as sewer systems and water treatment plants — can be difficult to maintain. Open defecation is widely practised in some countries, but it is not a suitable alternative. It contaminates food and water through flies and can be dangerous to girls and women, as it forces them to seek out isolated spots away from their homes.

But changing toilet practices is surprisingly difficult. “It’s something quite intimate,” says Rémi Kaupp, a sanitation engineer for the UK-based charity WaterAid. “People don’t want governments or agencies to impose what kind of toilet they have in their home. What they want is someone to deal with the aftermath.”

Three things we have learned by creating shit-flow diagrams – WaterAid

Three things we have learned by creating shit-flow diagrams. WaterAid Blog, June 2019.

How do you get a full picture of how a city deals (or doesn’t deal) with its waste? Rémi Kaupp, urban sanitation specialist, swears by shit flow diagrams…

Think about your city. Hundreds, thousands, maybe millions of people, going to the toilet, every day. Do you know where it all goes after the toilet? And, crucially, do you know how much of it is treated? wateraid

In many cities where WaterAid works, the answer is: not really. Authorities might have a rough estimate of the proportion of people who have a toilet, and also know where treatment plants are, if there are any – but that’s not the whole picture.

Introducing: the shit flow diagram

To get the full view, my colleagues have been using one of my favourite tools in sanitation: the shit-flow diagram (also called SFD, or ‘excreta-flow diagram’, if you prefer). An SFD looks like the festive picture below. For a given city, green arrows represent the proportions of excreta that are ‘safely managed’ along the whole sanitation chain: from the toilet, through a pit or septic tank, via sewers or sludge tankers, to treatment stations and eventual disposal or reuse.

Peri-Urban Sanitation – Water Currents, June 11, 2019

Peri-Urban Sanitation – Water Currents, June 11, 2019.

This issue of Water Currents highlights recent studies and resources on fecal sludge management, container-based sanitation, shared sanitation, and other topics. As noted in USAID’s Water and Development Plan included in the U.S. Global Water Strategy, separating individuals and communities from human waste, properly treating fecal waste, and promoting key behaviors that lessen the risk of illness are critical sanitation and hygiene interventions that reduce diarrheal disease, child mortality, malnutrition, neglected tropical diseases, and other waterborne illnesses, such as cholera. sanergy.png

The first six studies are from the Creating Demand for Peri-Urban Sanitation (SanDem) project, which aims to better understand how to improve the quality of peri-urban sanitation using demand-side/behavior change approaches in Lusaka, Zambia.

We would like to thank staff from Sanitation and Hygiene Applied Research for Equity (SHARE) for contributing content to this issue. SHARE generates evidence to improve policy and practice worldwide to achieve universal access to effective, sustainable, and equitable sanitation and hygiene.

Female-Friendly Public and Community Toilets: a discussion about why we need them and how to design them

Public and community toilets are often dirty, poorly maintained and have not been designed to meet the requirements of women and girls. But Governments and city planners can and should improve this situation by a) including women in the planning process and b) following basic principles of universal design that ensure public and community toilets are accessible for all users, are secure and well located, include context specific menstrual health features, cater for caring responsibilities (of all genders) and are maintained for cleanliness and safety. The practical “Female-friendly public and community toilets” guide is designed to help city authorities, planners and NGOs identify areas that lack public and community toilets and check if existing toilets are female-friendly while also giving some practical guidance for non-negotiable design elements. The webinar will highlight why it is important to look at public and community toilets through a gender lens, giving time for discussion and hoping for feedback from participants.

Presenters:
Priya Nath: Equality, Inclusion and Rights Advisor, WaterAid, UK
Olutayo Bankole Bolawole: East Africa Regional Director, WaterAid, Uganda
Lizette Burgers: Senior Advisor WASH, UNICEF, USA
Sam Drabble: Head of Research and Learning, WSUP, UK

The webinar will be recorded for those that cannot attend.

The social dynamics around shared sanitation in an informal settlement of Lusaka, Zambia

The social dynamics around shared sanitation in an informal settlement of Lusaka, Zambia. Journal of Water, Sanitation and Hygiene for Development, March 2019.

This study explored the social dynamics affecting collective management of shared sanitation in the Bauleni compound of Lusaka, Zambia. In-depth interviews were conducted with landlords (n = 33) and tenants (n = 33). Elinor Ostrom’s eight design principles for the management of common-pool resources was used as a framework to analyse the data. jnl

Social capital within plots was also assessed. Pit latrines were predominantly shared by landlords and tenants on residential plots. However, unwelcome non-plot members also used the latrines due to a lack of physical boundaries. Not all plot members fulfilled their cleaning responsibilities equally, thereby compromising the intended benefits for those conforming. Landlords typically decided on latrine improvements independent of tenants.

Latrines were not systematically monitored or maintained, but punishment for non-conformers was proportionate to the level of infraction. There was no system in place for conflict resolution, nor local organizations to regulate the management of sanitation. Lastly, there were few enterprises associated with peri-urban sanitation.

Social capital was moderately high, and tenants were willing to invest money into improving sanitation. The social dynamics illuminated here provide an important basis for the development of a behavioural intervention targeted towards improving urban sanitation.

Evaluating the Potential of Container-Based Sanitation – World Bank

Evaluating the Potential of Container-Based Sanitation. World Bank, February 2019.

In the face of urbanization, alternative approaches are needed to deliver adequate and inclusive sanitation services across the full sanitation service chain. Container-based sanitation (CBS) consists of an end-to-end service—that is, one provided along the whole sanitation service chain—that collects excreta hygienically from toilets designed with sealable, removable containers and strives to ensure that the excreta is safely treated, disposed of, and reused. cbs

This report builds on four case studies (SOIL – Haiti, x-runner – Peru, Clean Team – Ghana, Sanergy – Kenya) to assess the role CBS can play in a portfolio of solutions for citywide inclusive sanitation (CWIS) services.

The authors conclude that CBS approaches should be part of the CWIS portfolio of solutions, especially for poor urban populations for whom alternative on-site or sewer-based sanitation services might not be appropriate.

Customer satisfaction with existing services is high and services provided by existing CBS providers are considered safe but have some areas for improvement. While the proportion of total CBS service costs covered by revenues is still small, CBS services are considered to be priced similarly to the main sanitation alternatives in their service areas.

Recommendations include adopting a conducive policy and regulatory environment and exploring ways to ensure that CBS services are sustainably financed. The report also identifies areas for further analysis.
