Water, sanitation, and hygiene (WASH) form the cornerstone of public health, particularly in community health practice within Kenya. Effective management of WASH practices directly influences the control of communicable diseases, especially in densely populated urban settlements and rural areas where waterborne illnesses are prevalent. Community health professionals play a vital role in educating households on safe water use, proper sanitation, and hygiene behaviors to reduce disease transmission and improve overall health outcomes. This chapter establishes a foundation by defining critical terms and exploring the main sources of water relevant to community health interventions.
1.1 Definition of Terms
Understanding core terminology related to water, sanitation, and hygiene is essential for community health workers to communicate effectively with communities and stakeholders. Precise definitions underpin policy implementation, health education, and monitoring activities in Kenya's diverse environments.
1.1.1 Water
Water is a transparent, tasteless, odorless, and nearly colorless chemical substance essential for all known forms of life. In community health, water refers to any source used for drinking, cooking, cleaning, and personal hygiene. Its quality and availability directly impact health outcomes, especially in preventing waterborne diseases such as cholera and typhoid.
1.1.2 Sanitation
Sanitation encompasses the provision and maintenance of facilities and services for safe disposal of human urine and feces. It includes toilets, latrines, sewage systems, and waste management practices that prevent contamination of the environment. Proper sanitation reduces exposure to pathogens and is a critical factor in controlling diarrheal diseases in households and institutions like schools and health centers.
1.1.3 Hygiene
Hygiene involves behaviors and practices that maintain health and prevent disease spread, primarily through cleanliness. It includes handwashing with soap, safe food handling, and personal cleanliness. Hygiene promotion is a key community health strategy to interrupt transmission of infectious agents, especially in settings such as maternity wards and child care centers.
1.1.4 Waterborne Diseases
Waterborne diseases are illnesses caused by pathogenic microorganisms transmitted through contaminated water. Common examples include cholera, dysentery, and giardiasis. These diseases disproportionately affect vulnerable populations in informal settlements and rural areas with inadequate water and sanitation infrastructure.

Chapter Summary
This chapter provided a comprehensive overview of managing water, sanitation, and hygiene practices by first defining key terms related to these areas. It examined various water sources, including rainwater, surface water, underground water, and seawater, highlighting their relevance for domestic and community use. The characteristics that define potable water were discussed, emphasizing the importance of water being free from disease-causing organisms and harmful chemicals, as well as being pleasant in taste, colorless, odorless, and suitable for domestic purposes. The chapter explored diseases associated with water, categorizing them into waterborne, water-washed, water-based, and water-related vector diseases, and outlined essential water safety measures. Small-scale water treatment methods such as chlorination, boiling, solar disinfection, and filtration were described alongside the large-scale water treatment process, which includes aeration, coagulation, sedimentation, filtration, chlorination, and storage. Water quality control mechanisms were addressed to ensure safety and compliance with health standards. Sanitation methods were differentiated into non-water carriage systems like latrines and water carriage systems such as toilets, while community-led total sanitation phases were broken down into pre-triggering, triggering, and post-triggering stages. Finally, the chapter highlighted vital hygiene practices focusing on handwashing and home and food safety to prevent disease transmission and promote public health.
