EOS’ Water Chlorinator
Clorador ADEC
EOS International’s water purification technology is a low-cost, low-maintenance solution that attaches to any rural community’s water tank and inactivates pathogens in water systems by releasing a controlled dosage of chlorine. One system can provide safe drinking water for up to 1,000 community members and requires no electricity to use.
EOS International is committed to helping realize the United Nations’ Sustainable Development Goal 6 to “ensure availability and sustainable management of water and sanitation for all.” In addition to SDG 6, EOS’ work also supports gender equality, economic growth, climate action, relieving poverty, and good health.
Evidence Shows that Water Treatment is one of the Most Cost-Effective Ways To Save Children’s Lives
The impact of EOS programs have been studied, measured, and referenced by academic researchers, departments of health, and scientific evaluations.
