The disinfection of water using solar energy (SODIS) is a simple and inexpensive purification technique. The system has feast through the emerging world and is in everyday usage across over 50 nations both in Asia, Latin America, and Africa. Over an estimated 5 million people sterilise their intake water using solar disinfection (SODIS) method. Well water disinfection using solar energy (radiation) in Wukari town, the technique consists of placing water into transparent plastic or glass containers (normally 1 L PET beverage bottles) which are then exposed to the sun. Exposure times vary from 10am to 6pm depending on the intensity of sunlight and sensitivity of the pathogens. Its bactericidal outcome is built on the mutual effect of warm air heating of solar sunlit and UV radiation. It has been repeatedly shown to be effective for eliminating microbial pathogens and reduce diarrheal morbidity including cholera. Beginning from 1980 to date, report has shown that, much research has been conducted to explore the mechanisms of solar radiation induced cell death in water and conceivable improvement techniques of making it faster and safer. This report was on practical attempts to revise all relevant knowledge about solar disinfection from microbiological issues, laboratory research, solar testing and including real application studies, limitations, as well as examining the factors influencing adoption of the technique and health impact.
