SODIS (Solar Water Disinfection)¶
Sand Dams & Civil Works • Est. CapEx: $0 USD • Lifespan: 7–15 Years
Technical Overview¶
SODIS is a simple, low-cost household water treatment method that uses solar energy to disinfect microbially contaminated drinking water. It is recommended by the WHO and suitable for low-income communities and emergency settings.
Key Specifications & Engineering Parameters¶
| Parameter | Specification |
|---|---|
| Category | Sand Dams & Civil Works |
| Capital Cost (CapEx) | $0 USD |
| Power / Energy | 100% Gravity / Zero Power |
| Target Scale | Household (5–10 people) |
| Standard Lifespan | 7–15 Years |
| Technology Maturity | Commercially Available |
| Primary Mechanism | Microbially contaminated water is filled into transparent PET bottles and exposed to full sunlight for at least 6 hours. Solar UV-A radiation damages pathogen DNA, while increased water temperature creates synergistic disinfection effects, inactivating bacteria, viruses, and some parasites. |
