Better Water Information

In the sprawling urban slums of Asia and Africa, a hidden crisis unfolds daily: children living in dense, unplanned settlements often have no access to clean water or basic toilets, turning schools into epicenters of disease. While rural water projects dominate headlines, the unique challenge of urban poverty—where space is scarce, infrastructure is fragmented, and populations are highly mobile—demands a different solution. This is the niche that Splash has carved out with surgical precision, focusing exclusively on children in urban environments across eight countries. By installing robust water filtration systems, handwashing stations, and delivering hygiene education directly in schools, Splash aims to break the cycle of diarrheal disease and absenteeism. But does this targeted urban strategy offer the value and longevity that donors seek? Let’s dive into a comprehensive analysis of this A-ranked project.

Technology & Methodology

Splash’s approach is a tightly integrated, three-pronged model designed for high-traffic institutional settings. The core technology is a point-of-use water filtration system, typically installed at a central tap or drinking water station within a school. They utilize advanced hollow-fiber membrane filters (often from partners like Pentair), which are highly effective at removing 99.99% of bacteria, parasites, and protozoa without requiring electricity or complex plumbing. These filters are paired with durable, child-friendly gravity-fed water dispensers that ensure a constant supply of safe drinking water.

The second pillar is the installation of group handwashing stations. These are not simple buckets; they are purpose-built, low-cost, foot-pedal-operated or tippy-tap systems placed near latrines and cafeterias. The design promotes water conservation and reduces the risk of recontamination. The third, and arguably most critical, component is hygiene behavior change education. Splash trains teachers and local “WASH champions” to deliver a standardized curriculum covering critical handwashing times (after using the toilet, before eating) and safe water storage practices. This methodology ensures the hardware translates into sustained health outcomes, not just temporary infrastructure.

Cost-Effectiveness & Sustainability Analysis

With a cost per person of just $25 and an expected lifespan of 10 years, Splash presents a compelling value proposition. To put this in perspective, the cost is roughly equivalent to a single clinic visit for a child with severe diarrhea. Over a decade, that $25 investment provides daily access to safe water and hygiene facilities. The annualized cost is a mere $2.50 per child per year.

However, the sustainability model requires scrutiny. The 10-year lifespan is contingent on the filter cartridges being replaced every 6-12 months (a recurring cost not fully covered in the initial $25). Splash addresses this by establishing local supply chains and training school management committees to collect small maintenance fees from parents or local government. Their “urban focus” actually aids sustainability: schools in cities are easier to monitor, have better access to replacement parts, and are less likely to be abandoned than remote rural wells. The risk lies in long-term ownership—if the school administration changes or funding dries up, the system can fall into disrepair. Overall, for a school-based intervention, the cost-efficiency is excellent, but it is not a “set-and-forget” solution.

Regional Impact: Asia & Africa

Splash’s work is concentrated in the urban belts of India, Ethiopia, and Nepal, three countries with stark contrasts in water challenges but a shared struggle with urban slum growth.

India: In cities like Kolkata and Mumbai, Splash targets municipal schools serving families from informal settlements. The impact is profound—reducing waterborne illness allows children, especially girls who often miss school during menstruation due to lack of clean facilities, to stay in class.
Ethiopia: In Addis Ababa, rapid urbanization has overwhelmed water infrastructure. Splash’s filtration systems are a lifeline in schools where tap water is often contaminated. The handwashing stations are critical here, as hygiene practices are often limited by water scarcity.
Nepal: In Kathmandu Valley, post-earthquake reconstruction and groundwater contamination make Splash’s interventions vital. The program’s emphasis on earthquake-resilient infrastructure (like flexible piping) shows adaptation to local risks.

The insight that Splash “has less rural reach” is accurate but not a weakness—it is a strategic strength. By focusing on high-density urban schools, they achieve a high number of beneficiaries per installation, lower maintenance costs, and easier monitoring than a dispersed rural model.

WASH Expert Assessment

Overall Rating: A

Splash earns its A-rating through exceptional cost-effectiveness, a robust and proven technology stack, and a clear, scalable model tailored to a specific, underserved niche: urban poverty. The integration of hardware (filters, stations) with software (hygiene education) is textbook WASH best practice. The primary limitation is the dependency on the school ecosystem—if the school closes or the community disengages, the infrastructure is orphaned. However, the 10-year lifespan and $25 cost-per-person represent one of the highest returns on investment in the sector. For donors seeking to maximize impact in urban slums and improve child health outcomes, Splash is a top-tier, evidence-based choice.
