Module 8: Innovations in Sanitation

Case Study 1: Creating Low-Cost Urban Water Supply and Sanitation

Low-income families cannot afford to invest in sewage systems. Thus, water supply and sanitation provision in urban areas and large villages should be for groups of households, not to individual households, to alleviate costs. Groups of households could form water and sanitation cooperatives. In this way, very poor households would be served by community-managed sandpipes and sanitation blocks.(1) This type of grouping helps to reduce costs. For example, in the city of Parauapebas, Brazil, significant cost savings were achieved because there was a much lower total pipe length for the public distribution network. This meant that substantially less “public” excavation was required.

However, there are views held against this. Some say that “you will not get poor households in this country to cooperate with each other” and “it could not possibly work here as our situation is so very different”. (2) There is also validity in the belief that each household should, wherever possible, have access to its own sanitation facility. A water cooperative, however, can enable member households to decide which service level they will each have. Examples of on-site systems include VIP latrines, pour-flush toilets, and ecological sanitation toilets. VIP latrine alternatives may include urine-diverting, ventilated improved vault (VIV) latrines.(3) These types of alternatives provide a cooperative, cost-effective, yet individualized option for households.

Case Study 2: The World Toilet Organization (WTO)

The World Toilet Organization (WTO) is a global non-profit organization committed to improving toilet and sanitation conditions worldwide. WTO aims to connect with poor by branding toilets as status symbol and an object of desire. WTO is building a market infrastructure where the poor demand toilets, thereby breaking the taboo about toilets and sanitation and instead making it a mainstream topic. WTO organizes successful World Toilet Summits where organizations can learn from one another. The summits address critical issues about toilets and sanitation technology, development, funding for design and maintenance, social entrepreneurship, research, and various other related topics. WTO started the first World Toilet College (WTC) to provide training in toilet design, maintenance, school sanitation, disaster sanitation, and implementation of sustainable sanitation systems. WTO was honored as an Ashoka Global Fellow for its excellence in social entrepreneurship.

Field implementation of the sanitation project began in April 2009. The purpose of the project was to initiate and strengthen behavior change activities by building on Community-Led Total Sanitation initiatives where possible. An additional goal was to reduce cost of water and sanitation components by creating upgradable latrine designs and by developing social enterprises to improve technical and business management skills. The project sought to empower households to participate in the creation and prototype development of latrines.(4)

Case Study 3: Sanitation in India and African Countries: Achieving the Sanitation Millennium Development Goal(5)

According to the UN, there is greater access to cell phones than access to toilets in India. Only 31% of the population had access to improved sanitation in 2008. “It is tragic irony to think that in India, a country now wealthy enough that roughly half of the people own phones, about half cannot afford the basic necessity and dignity of a toilet,” says Zafar Adeel. It is also important to provide education about the health dangers of poor sanitation. Cultural taboos surround this issue in some countries, preventing progress. In Africa, the number of people served must double from 350 million served in 2006.

At the current rate of progress in Sub-Saharan Africa, the sanitation MDG might not be met until 2076. Once girls reach puberty, lack of access to sanitation becomes a central cultural and human health issue, contributing to female illiteracy and low levels of education. This contributes to a cycle of poor health for pregnant women and their children.(6)

A report released by the UN offers recommendations for achieving the Sanitation Millennium Development Goal:

Case Study 4: Ikotoilet- “Toilet Here” in Nairobi(7)

Ecotact is a Nairobi-based company that aims to improve the urban landscape for low-income communities through environmentally friendly projects in sanitation and housing. Using the Ikotoilet project, Ecotact builds and operates high-quality, public, pay-per-use toilet and shower facilities on public land in urban centers. Ecotact uses a Build-Operate-Transfer model of public-private partnership, entering into long-term contracts with municipalities to secure use of public lands. In exchange for use of public land, the company agrees to cover facility construction costs, but renounces ownership of the facilities to the municipalities. The contracts give Ecotact the right to operate the toilet and shower facilities for a certain number of years and charge user fees. The company hires staff to operate and clean the units after each use, and complements the sanitation offerings with other revenue-generating products such as shoeshine services, soft drink sales and newspaper sales.

Ecotact’s facilities are creating a new standard of hygiene in target communities, reducing urban pollution from human waste, generating employment opportunities for low-income individuals, and restoring dignity to sanitation services among the urban poor. Ecotact plans to replicate its model to 200 facilities across Kenya over the next five years.

Case Study 5: SOIL(8)

Using waste transformed into soil as inspiration, SOIL transforms discarded materials and pollutants into valuable resources. SOIL has installed more than 50 public ecological toilets for schools and community groups in five of Haiti’s ten departments. SOIL is focusing on these sanitation programs:
