Water and sanitation, collectively referred to as Water, Sanitation, and Hygiene (WASH), constitute the foundation of public health systems and national resilience. Reliable access to safe water and effective sanitation is essential not only for disease prevention, but also for economic productivity, human dignity, and long‑term state capacity. In fragile and water‑scarce environments such as Somaliland, WASH must be treated as a strategic public health and governance priority rather than a purely humanitarian concern.

Defining Water and Sanitation

Water supply refers to the provision of safe, accessible, and reliable water for drinking, food preparation, hygiene, and domestic use. Safely managed water originates from an improved source—such as piped systems, boreholes, or protected wells—that is available on premises when needed and is free from fecal and priority chemical contamination.

Sanitation encompasses the infrastructure and services required for the safe management of human excreta from containment to final disposal or reuse. Its central objective is to prevent human waste from contaminating people, water sources, and the environment. Effective sanitation systems include toilets, latrines, sewer networks, wastewater treatment, and sludge management.

Public Health Impacts of WASH

The link between WASH and health outcomes is direct and well established. Where water and sanitation systems are inadequate, the environment becomes a primary vector for disease transmission.

Improved WASH reduces the spread of fecal‑oral diseases such as cholera, typhoid fever, dysentery, hepatitis A, and intestinal parasitic infections. Diarrheal disease remains among the leading causes of mortality for children under five globally, and evidence consistently shows that improved WASH can reduce diarrheal incidence by up to 45 percent.

Beyond acute infection, inadequate sanitation contributes to chronic conditions. Repeated exposure to enteric pathogens leads to Environmental Enteric Dysfunction (EED), a subclinical disorder that impairs nutrient absorption and weakens immune function. This condition is a major contributor to childhood stunting, undermining physical development, cognitive outcomes, and future economic productivity.

WASH is also critical for maternal and neonatal health. During childbirth, unsafe water and poor sanitation increase the risk of sepsis, a leading cause of maternal and newborn mortality. High‑quality WASH services in healthcare facilities are therefore indispensable for safe delivery and postnatal care.

Socioeconomic and Productivity Benefits

The benefits of water and sanitation extend well beyond health. Reliable water access reduces the time burden of water collection—an activity that disproportionately affects women and children—thereby enabling greater participation in education and labor markets. At the national level, reductions in preventable disease lower healthcare expenditures and strengthen the overall resilience of health systems.

Protecting the “Safe Water Chain”

Public health protection depends on maintaining the integrity of the entire “safe water chain.” Even when water is safe at the source, contamination can occur during transport, storage, or household use. Effective WASH strategies therefore address multiple points: protecting water sources from runoff and fecal intrusion; promoting the use of clean, covered transport containers; encouraging safe storage using narrow‑necked vessels; and applying point‑of‑use treatment methods such as boiling, chlorination, or filtration where source quality is uncertain.

Strategic Health Cooperation and State‑Building

Following the formal recognition of Somaliland by Israel in December 2025, WASH has emerged as a strategic pillar of bilateral health cooperation and institutional development. In an arid context where health security is inseparable from water security, this partnership creates opportunities to integrate technological innovation with public health governance.

A central priority is water‑secure health infrastructure. Many health facilities in Somaliland lack consistent access to sterile water, undermining infection prevention, and clinical operations. The deployment of decentralized desalination and atmospheric water generation units at regional hospitals and the planned Somaliland Center for Disease Control can ensure uninterrupted water availability. Complementing this, small‑scale onsite wastewater treatment systems can prevent untreated medical effluent from contaminating surrounding groundwater.

Surveillance, Laboratories, and Early Warning Systems

Effective disease control requires a “One Health” approach that integrates environmental and clinical data. Wastewater‑based epidemiology, successfully implemented in Israel for monitoring COVID‑19 and polio, offers a cost‑effective method for early detection of cholera, typhoid, and other outbreaks in urban centers such as Hargeisa and Berbera. Integrated laboratory services capable of testing both clinical samples and water quality are essential to professionalize public health institutions and strengthen regulatory capacity.

Capacity Building and Emergency Integration

Sustainable impact depends on human capital. Recent training initiatives for Somaliland water professionals demonstrate the value of structured knowledge transfer. Collaborative development of professional standards for water and health officers can strengthen regulation at the point of consumption while reinforcing merit‑based governance. Integrating WASH protocols into emergency medical services training—modeled on Israel’s Magen David Adom system—can further enhance outbreak response, especially during flood‑related disease surges.

Water, Nutrition, and Health

Water management also links public health to food security. Community gardens supported by efficient drip‑irrigation systems near health facilities can improve dietary diversity and nutritional intake. This integration addresses the underlying determinants of stunting and reinforces immune resilience against waterborne disease.

Cultural Institutions and Behavior Change

In Somaliland’s oral and culturally rich society, public health interventions are most effective when reinforced through trusted cultural institutions. The National Theatre and other cultural platforms serve as conduits between scientific guidance and community practice. Traditional Somali theatre (riwaayad), poetry (gabay), and proverbs (maahmaahyo) can translate abstract health concepts into familiar narratives, reduce stigma around sanitation, and frame hygiene as a component of national strength and modern statehood.

In the Horn of Africa, water and health are inseparable. Integrating WASH into health systems, surveillance, education, and cultural life is essential for Somaliland’s public health security and long‑term national resilience. Strategic partnerships that combine technology, institutional development, and cultural legitimacy can transform WASH from a humanitarian necessity into a cornerstone of sustainable state‑building.
