Predictors of Functional Status and Abandonment of Tippy-Tap Handwashing Technology Following CLTS Programme Exit in Traditional Authority Chiwere, Dowa District, Malawi: A Cross-Sectional Analytical Study
This cross-sectional study in Malawi reveals that the dramatic post-programme collapse of tippy-tap handwashing technology was driven not by knowledge deficits but by household labor constraints, specifically the presence of young children and smaller household sizes, suggesting that future interventions should prioritize maintenance support for these vulnerable groups over repeated sensitization.

In many rural villages across sub-Saharan Africa, a simple device known as a tippy-tap has been promoted as a life-saving solution. It is a low-cost, foot-operated water dispenser made from locally available materials like buckets, sticks, and rope. The design is clever: a person tilts the bucket with their foot to release a stream of water, allowing them to wash their hands without touching a tap that might be dirty or unavailable. These devices are central to a public health strategy called Community-Led Total Sanitation, which relies on communities to build their own sanitation infrastructure rather than waiting for outside aid. The logic is straightforward: if people have a way to wash their hands with soap and water, the spread of diarrheal diseases and respiratory infections drops significantly. Yet, a persistent puzzle haunts development workers. While these devices are often built in great numbers during the initial push of a health campaign, they frequently disappear or stop working once the external support team leaves. The question is not whether people know how to build them, but why they stop using them.
A team of researchers from the University of Livingstonia in Malawi set out to solve this mystery in the Chiwere area of the Dowa District. This region had seen a remarkable success story in 2018, when nearly every household had a tippy-tap after a sanitation campaign. However, by 2022, after the organization that helped build them had departed, the number of households with a working device had plummeted to a tiny fraction of the original count. To understand what happened, the researchers visited hundreds of homes in 2024. They did not just count the devices; they asked people what they knew about how to build and fix them, how they felt about handwashing, and what their daily lives looked like. They were looking for the specific reasons why a device that was once everywhere had become so rare.
The investigation began by checking the knowledge of the community. The researchers expected to find that people had forgotten how to make or repair the taps, or that they no longer believed in their value. Instead, they found that the vast majority of people remembered exactly how the devices worked and understood why they were important. Almost everyone could explain the construction and maintenance steps, and their attitudes toward handwashing remained positive. The knowledge was there, and the desire to be healthy was there, yet the devices were gone. This discovery ruled out the idea that the collapse was caused by a lack of education or a loss of motivation. The problem lay elsewhere.
When the researchers looked closely at the few households that still had a tippy-tap, they examined which ones were actually working and which had broken down. They found that the devices were most likely to be non-functional in homes with specific characteristics. The strongest predictor of a broken or missing device was the presence of a very young child, specifically one under the age of five. Households with a toddler were significantly less likely to have a working tap than those without. Similarly, smaller families with only one or two members were also less likely to maintain a working device compared to larger families. The researchers noted that this was not about the parents not caring; rather, it suggested that the daily demands of caring for a young child or the lack of extra hands in a small family made it difficult to find the time or labor needed to fix a broken device when it inevitably broke.
The study also considered the role of outside help. The researchers checked if households that had recently been visited by health promoters were more likely to have working devices. They found no connection between recent visits and whether a tap was working. This suggests that simply telling people to fix their devices or visiting them more often does not solve the problem. The issue is not a lack of reminders, but a lack of capacity to act on those reminders when life gets busy or when a device breaks. The structural support that existed while the health campaign was active had vanished, and without that support, the daily pressures of family life took over.
The findings paint a clear picture of a technology that failed not because it was bad or because people didn't understand it, but because the environment around it changed. The tippy-tap is a simple tool, but keeping it working requires a steady supply of time, labor, and materials. In households already stretched thin by the needs of a young child or the limited workforce of a small family, the extra effort to repair a broken tap became too high a price to pay. The researchers conclude that future health programs need to change how they measure success. Instead of counting how many devices are handed out, they should focus on keeping the ones that exist working. To do this, support systems must be designed to help the households that are most vulnerable to breakdown, particularly those with young children, rather than just repeating the same messages about hygiene to everyone. The solution is not more education, but a better understanding of the daily realities that prevent a good idea from surviving on its own.
