SODIS - Burkina Faso

SODIS (Solar Water Disinfection) is a simple and effective method used in Burkina Faso and many other countries to purify drinking water using sunlight. This topic discusses the implementation of SODIS in Burkina Faso.

Solar Water Disinfection (SODIS)

• SODIS is a low-cost and environmentally friendly method to make drinking water safe by using sunlight.

Key Steps in SODIS

• Filling: Collect water from a trusted source and fill transparent plastic bottles to about 75% full.
• Sun Exposure: Place the bottles in direct sunlight for at least 6 hours on a sunny day (if cloudy, expose for 2 consecutive days).
• Pathogen Inactivation: Solar UV-A rays and heat from the sun inactivate harmful microorganisms, making the water safe to drink.

Advantages of SODIS in Burkina Faso

• Simplicity: SODIS is easy to understand and implement, making it accessible to rural communities with limited resources.
• Cost-Effective: It requires only transparent bottles, sunlight, and time, making it affordable for the population.
• Safe Drinking Water: Effectively kills pathogens, reducing the risk of waterborne diseases.
• Environmental Friendliness: SODIS does not involve the use of chemicals or fuel, making it eco-friendly.

Challenges in Implementing SODIS

• Weather Dependency: SODIS effectiveness depends on sunlight, which can be inconsistent in some regions.
• Education: Ensuring that communities are educated about the proper SODIS technique is essential for its success.
