Solar Water Disinfection (SODIS)¶

Disinfection & Chlorination • Est. CapEx: Low-cost / Locally fabricated

Technical Overview¶

A simple, low-cost method that uses sunlight to kill pathogens in water. Suitable for households in developing regions with limited access to clean water.

Key Specifications & Engineering Parameters¶

Parameter	Specification
Category	Disinfection & Chlorination
Capital Cost	Low-cost / Locally fabricated
Primary Mechanism	Clear plastic or glass bottles filled with contaminated water are exposed to full sunlight for at least 6 hours (or 2 days if cloudy). UV-A radiation and increased temperature work synergistically to inactivate bacteria, viruses, and protozoa.
Target Scale	Household / Village Cluster
Standard Lifespan	10 - 20 Years
