This is an ongoing compilation of statistics that shows that failure rates for water systems, latrines, and hygiene promotion campaigns are still high after decades of intervention.
- Tanzania: national mapping shows 38% of 74,331 water points are not functional, and 7% are functional but need repair (Water Point Mapping Tanzania)
- Ghana: 21% of 1,509 water points were not functioning on the day of visit (Samani, Destina and Patrick Apoya, Sustainable Water Service Delivery Project: Study Findings, 2013 Water and Health Conference, Chapel Hill, NC.)
- Ethiopia, Kenya, Sierra Leone, Uganda: In a study commissioned by Plan, nearly 5000 households in 116 villages were re-assessed according to the original open defecation free (ODF) verification criteria. If all five criteria below are applied, the overall slippage rate across the study was 92%. In all countries each household was expected to have:
- A functioning latrine with a superstructure
- A means of keeping flies from the pit
- Absence of excreta in the vicinity of the house
- Hand washing facilities with water and soap or soap-substitute such as ash
- Evidence that the latrine and hand washing facilities were being used (FH Designs, 2013)
- South Africa: an informal survey of toilets at schools that fall within four of the National Health Insurance pilot districts found that at all 17 schools the toilets were in a shocking condition (AllAfrica, 2013)
- India: In Bihar, a common practice once the pit was full was to revert to the practice of open defecation. The percentage of the population going back to open defecation was close to 90% (an educated guess as there is no monitoring of latrine usage) (Tremolet & Binder, 2013).
- Uganda:16% of rural improved water points were non-functional (MWE, Republic of Uganda, 2013)
- Uganda: Only about 7% of 377 surveyed households reported that their village hand pumps had never failed, while the rest reported that their pumps failed nearly every month (14.5%), about twice or more in a year (54%) or once a year (15.6%). Some of the non-functional water sources were considered ‘landmarks’ by the village residents (Mugumya, 2013).
- Malawi: In a service level survey of 48 villages, it was surprising to note that 66% of MALDA handpumps installed one year ago failed both pump tests and were therefore recorded as being non-functional. The proportion of fully functional MALDAs was between 29% and 50% in all age cohorts (Shaw & Manda, 2013).
- Malawi: The majority of latrines in all studied areas had no handwashing facilities available: the sample average was 44%.(evidence suggests this surrogate marker is one of the most reliable indicators of actual practice) (Shaw & Manda, 2013).
- Nepal: The National Management Information Project shows that of 40,000 gravity flow schemes, 82% are not fully functional (Mahato, RWSN e-discussion, June 10, 2013).
- Uganda: 19% of 79,413 water points are not working. Shallow wells have the highest non-functionality rates (approximately 30%), while protected springs have the lowest non-functionality rate (approximately 88%). As many as 2,303 point water sources (2.9%) are considered abandoned, having been non-functional for five or more years. (Nekesa & Kulanyi, 2012)
- Haiti:A survey of 1096 water kiosks and 2266 water fountains showed that more than half of existing water kiosks are out of service in four geographical departments: Nord (63%), Sud (60%), Grand’Anse (59%) and Artibonite (53%) and 41.6% of existing water fountains inventoried are not functional (DINEPA, 2013)
- China: World’s biggest eco-toilet scheme fails: The dry toilets in Inner Mongolia’s Daxing eco-community have been quietly replaced after three years of bad smells, health problems and maggots (The Guardian, 2012)
- Cambodia: In areas where community-led total sanitation (CLTS) methods were used to promote latrine use, only about 15% of households with a latrine use the toilet regularly, while the rest keep going to the bush for defecation (WSP, 2012).
- Honduras: Of the 106 water systems assessed across Honduras, about half were in fact rehabilitations of existing systems, taking about one-third of the total investments made in the period under review (WASHCost, 2012)
- Kenya: the construction of new school latrines actually increased health risks among girls because hygiene behavior did not improve (L.E. Greene et al, 2012)
- Sierra Leone: A comprehensive water point mapping exercise (more than 28,000 water points) in 2012 showed the rate of damage of public water points is high and rises rapidly with point age. Among points built in 2007, 31% are impaired, and 17% are broken down. Furthermore, up to 40% of protected in-use points providing insufficient water during the dry season. (Sierra Leone Ministry of Water Resources, 2012)
- Swaziland: A pilot water point mapping effort in 8 Tinkhundlas (sub-districts) beginning Nov 2010 showed that out of 2689 water points, 58.6% are functional, 11.5% are partially functional, and 29.9% are non-functional. (Government of the Kingdom of Swaziland Ministry of Natural Resources & Energy, Department of Water Affairs, Water & Sanitation Point Mapping Pilot Project Report 2012)
- Ghana: In three districts (East Gonja, Akatsi, Sunyani West), more than 30% of the surveyed infrastructure was not functional, and as little as 2% was providing the basic level of service for which it was intended (Marieke Adank, IRC, 2012).
- Tanzania: One in four public kiosks were not functional at the time of an interview of 324 residents of Dar es Salaam (Listening to Dar, 2012)
- DR Congo: Water mapping in three provinces gave these results (Hambadiahana & Tolsma, 2012. Water Point Mapping in DR Congo)
Percentages/Number Province Bas Congo Province Equateur Province Kinshasa Water Points
Non-functional or partially functional protected water points
Non-functional or partially functional boreholes

Protected water points without a water payment mechanism
Sub-Saharan Africa: In a survey of 23 European Community-funded projects in six sub-Saharan countries (European Court of Auditors, 2012):
- Overall, equipment was installed as planned and was in working order.
- However, fewer than half of the projects examined delivered results meeting the beneficiaries’ needs.
- While the projects examined promoted the use of standard technology and locally available materials: they were sustainable in technical terms, for a majority of projects, results and benefits will not continue to flow in the medium and long term unless non-tariff revenue is ensured; or because of institutional weaknesses (weak capacity by operators to run the equipment installed).
- Mali: in four municipalities, non-functionality of “modern” water points ranged from 14 to 41% (Jones, 2013)

- India: The Total Sanitation Campaign was intended to be a community-led, people-centered, demand-driven and incentive-based program to address India’s rural sanitation crisis. But outcomes were remarkably poor. 2011 census data showed 31% sanitation coverage, far from the 68% reported by the Government. “The decade has witnessed progress slowing down and the number of rural households without latrines increasing by 8.3 million.” (Hueso & Bell, 2013)
- Kenya: Of 100 water systems assessed (built between 2006-2010), 75% are still in use. 45% are affected by minor technical issues, or even serious damages, although they have the potential to be remediated. 14% of the systems are non-functional (Welthungerlife, 2011)
- Liberia: 40% of over 10,000 improved water points mapped nationally were failed or needed repair (Government of Liberia, 2014)
- Liberia: The first systematic sampling of water points and study of water quality in Monrovia found that 57% of the water points were contaminated by E. coli, which is an indicator of widespread fecal contamination. The health standard for E. coli is none present/detected. (How a City Gets its Drinking Water: A Case Study – Capital City of Monrovia, Liberia, Vincent W. Uhl, Ashish Daw and Jaclyn A. Baron, 2012)
- 100% of the unprotected hand-dug wells sampled showed the presence of E. coli.
