Safe drinking water is essential for human health and sustainable development. When water is consumed without adequate disinfection or treatment, it may contain harmful microorganisms that cause serious water-related diseases. Worldwide, contaminated drinking water remains one of the leading causes of preventable illness, particularly in regions with limited access to reliable water treatment and sanitation infrastructure.

The following document provides an overview of common water-based diseases and explains how they are transmitted through unsafe drinking water. These diseases include bacterial, viral, and parasitic infections that can lead to acute illness, long-term health complications, and in severe cases, death.

Understanding the health risks associated with undisinfected water is a critical step toward prevention. According to the World Health Organization, effective water disinfection is one of the most important measures to reduce waterborne diseases and protect public health.

This document is published to raise awareness and to underline the importance of reliable water treatment solutions as a foundation for health, resilience, and economic stability.
