ANSWER
Sanitation System Design for a 200-House Community in South Africa
Poor sanitation remains a major global health risk. Approximately one-third of people
worldwide lack basic sanitation, leading to preventable diseases and deaths. Safe and
reliable sanitation is essential for health, mental well-being, and environmental
protection (World Health Organization, 2018). In South Africa, waterborne sewerage is
common in urban areas; however, many rural communities depend on decentralized or
on-site systems such as septic tanks or ventilated improved pit (VIP) latrines due to
lower cost and adaptability (Still & Foxon, 2012). These systems, however, are often
