This is an ongoing compilation of statistics to show that failure rates for water systems, latrines, and hygiene promotion campaigns are still high after decades of intervention.
- 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)
- 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

Sub-Saharan Africa: In a survey of 23 EC-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).
- 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: Of about 7000 improved water points in rural areas, 60% are fully functional, 29% are broken down, and 10.7% are working but have problems (Liberia WASH Consortium, 2011)
- 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.
- 75% of the kiosks sampled showed the presence of E. coli.
- 67% of the LWSC city water taps sampled showed the presence of E. coli.
- 52% of the protected hand-dug open wells fitted with hand pumps showed the presence of E. coli.
- 44% of the drilled wells fitted with hand pumps showed the presence of E. coli.
- Rwanda: In a baseline survey of 126 water points in the District of Kicikuro, only 41% provided enough water for the community every day of the year. 50% of the water points had been down for more than 1 day in the last month. 55% of the communities reported that they had no spare parts on hand for the water system (Water For People, 2011)
- Iraq: An evaluation of a WASH program in Iraq found no positive outcomes resulting from the hygiene campaign (NCA, 2011)

- 54% of 65,000 water points nationwide are operational; 75% of points that are only two years old.
- Nearly half (46%) of public improved water points in rural areas are not functioning.
- Almost half of all investment in rural water supply is effectively wasted.
- Up to 7.5 million rural Tanzanians lack access to clean and safe water due to functionality problems.
- Pakistan: (Asian Development Bank Independent Evaluation Group, 2009) an independent study of ADB’s assistance to rural water supply in the Punjab Province identified, among others, these major concerns:
- 20% of the subprojects are nonfunctional
- only 43% of community based organizations responsible for subprojects are functional and their capacity remains weak.
- Nepal: A study of Community-led Total Sanitation (CLTS) effectiveness showed while all but one of the communities studied had achieved open-defecation free (ODF) status, there was evidence of fairly widespread non-compliance in the form of now-hidden open defecation (WaterAid 2009)
- Timor-Leste: An assessment of all (134) rural water supply systems in Covalima district found: of 54 piped systems, 44% were fully functional, 30% partially functional, and 26% not functioning. Of the 80 hand pumps, 11 were under construction, 41% of completed systems were fully functional and 59% not functioning (Oxfam, 2008).
- India: An estimated 50% of subsidized toilets remain unused or are being used for purposes other than sanitation. (WSP. 2007)
- South Africa: In a sample of water and sanitation projects in all nine provinces, the compliance level for 1067 completed household water projects was only 2.6% – more than 97% of the projects did not comply with policy requirements, norms and standards. The compliance level for 517 completed household sanitation projects was 0% – that is, none of the completed household sanitation projects complied with policy requirements, norms and standards (CSIR, 2007).
- Sub-Saharan Africa: Figures collated by the Rural Water Supply Network in 2007 indicate an average rate of 36% non-functionality for hand pumps across 21 countries. This level of failure represents a total investment of between $1.2 and $1.5 billion in the last 20 years. (Triple-S, 2009)
- Ghana: In a study in rural areas, 60% of new latrines (0-2 years) are being used (Rodgers, 2007).
