Solar water disinfection (Sodis)  is a practical option for the treatment of domestic water that is available and easily manageable.  Clean containers are exposed to sunlight which treats microbial contaminants transmitted by water, through the use of combined antimicrobial effects of UV rays and heat of the sun together. This will provide one of the most economical and simplest method of water disinfection, especially in small communities and rural geographic conditions countries like Iran, where more than seventy to eighty percent of the year are sunny days. Limitations of solar disinfection systems include access to water containers and other required materials, lack of sunlight for disinfection, potential problems in water treatment with high turbidity and the availability of simple methods for reducing water turbidity before solar treatment, lack of residual disinfectant to protect water during handling and storage.Potential objections to the technology because of the long time required for water treatment (several hours or more) may protest the controversial flavor and odor that is leaking water from plastic bottles. But despite these limitations, solar disinfection in clear plastic bottles, one of the most promising and most extensively tested methods for disinfection of household water stored in containers. SODIS can provide pure drinking water every day for people living in remote areas without access to safe drinking water. Once installed it is entirely sustainable, needing only the energy from the sun to operate effectively. Households can therefore get pure drinking water with no running costs. In 2011 one billion people did not have direct access to safe drinking water.

Rural and small communities in Iran. SODIS  will be located all around the world where safe drinking water problems are. It will take place in isolated areas and near salt and/or brackish water. The solution was developed for rural environment where the people haven’t a direct access to safe drinking water. The proposed solution can be located anywhere.

Inspired by the natural water cycle, solar disinfection technices of desalination of water used to treat polluted  water or brackish water as well as any non-potable water (water analysis on request). This technique works for a long time with low performance and no industry.

Sodis is very low cost… The SODIS  will be produce safe drinking water over 10 years. The WaterPOD lies in the distillation process by solar energy inside a robust wooden structure, 100% free standing, with no running costs, to produce a greater volume of pure water than is available from small systems currently available.
As well, the environmental impact will be very skinny because of raw materials. Wea mainly use ecological materials.

All products developed by The Source SODIS Company are made to change water consumptions.
SODIS  could be produce 4 to 6 liters of pure water every day, and that for more than 20 years.
We will expect to provide a sustainable access to safe drinking water for each human people all over the world. In 2011 one billion people did not have direct access to safe drinking water.

SODIS  can provide pure drinking water every day for people living in remote areas without access to safe drinking water.This solution could work in sunny areas such as Africa,Asia or Oceania with salt or brackish water areas near of communities (households, tribes,…). Especially in small communities and rural geographic conditions countries like Iran, where more than seventy to eighty percent of the year are sunny days. The project must be supported both politically and financially by regional collectivities and governments.

SODIS commitments are:
- Provides safe drinking water for isolated persons all around the world and fight the pandemic water diseases.
- Social and environmental responsibility: Analyze envaronmental practices with a view to reducing the ecological impact of our activities.
