iDE Launches New Toilet Project
Lack of access to sanitation is a major problem affecting the developing world. Poor sanitation is a major cause of diarrheal disease, lost labor productivity for adults, missed school days for children, and additional financial burdens for families requiring medical treatment. In Cambodia alone, diarrheal diseases account for 17 percent of deaths in children under five. The World Bank recently estimated the annual economic loss due to poor sanitation there to be $448 million a year, which is equivalent to 7.2 percent of GDP.
Existing markets for rural sanitation in the developing world are woefully underdeveloped. Low demand and weak supply chains hinder the availability of sanitation products and services. Publicly funded sanitation projects often make extensive use of hardware subsidies with disappointing results; typically, only a fraction of the subsidy reaches the intended target group, and recipients often do not use or maintain their latrines over time.
For a number of years now in Asia, iDE has been at the forefront of Sanitation Marketing developments to address these challenges. iDE recently completed a pilot project in Cambodia that exceeded expectations by enabling 9.6 percent of the rural population to purchase sanitary latrines in eleven target districts over a 16-month period.
Now, a grant from the Bill & Melinda Gates Foundation has made it possible to expand these achievements on a national scale, improving the sanitation conditions of tens of thousands of rural households while stimulating vibrant and sustainable sanitation markets. Over a three-year period, the Cambodia Sanitation Marketing Scale-Up Project will build on the original pilot project by working directly with some 90 local enterprises, encouraging them to invest their own resources into addressing the demand for sanitary latrines.
The project will enable 115,000 households in 60 districts of Cambodia to purchase affordable sanitary latrines. Other outcomes include:
• Improved latrine designs for two “challenging environments”
• Sanitation financing mechanisms for consumer households and supply chain enterprises
• A research and training center to become a global dissemination platform for Sanitation Marketing experience
The total cost of the project is estimated at $6,942,199. The Bill & Melinda Gates Foundation has awarded iDE a grant of $3,987,717. Other key partners in the project include the Stone Family Foundation, the World Bank Water and Sanitation Program, PATH, and the Royal Government of Cambodia.
Sanitation Marketing has emerged as a highly effective approach for rapidly and sustainably improving rural sanitation at scale by connecting consumers with products that they want and can afford. Evidence from a number of recent projects demonstrates that stimulating private enterprises to address the untapped rural sanitation market can have a revolutionary impact on the uptake of sanitary latrines—with associated health and financial gains for rural households.
The Sanitation Marketing model leverages the advantages of private sector entities, civil society, and government to reach large numbers of rural households in short time frames. Donor funds are not used to provide direct subsidies for hardware or installation. Instead they are invested in laying the foundations for demand-driven, self-financing market systems.
Broadly, Sanitation Marketing applies iDE’s market-based poverty alleviation approach to the related problem of inadequate sanitation. First, we develop a deep understanding of the target group’s needs and aspirations, and adapt or design affordable technology options to meet those needs. We strengthen the capacity of local enterprises to manufacture and deliver the technologies, conduct social marketing campaigns to encourage the purchase and proper use of the technologies, and coordinate with NGOs, microfinance institutions, and government agencies to extend scale and to reach poorer households.
