Transcription de la présentation

  1. SUBJECT: Health Concerns in Small Remote Villages Due to Lack of Safe Drinking Water and Sanitation Facilities. Need: 1.2 billion people in the developing world have no access to safe drinking water. OBJECTIVE: Provide one or more water taps in small remote villages where potable water is available for drinking, cooking, washing, and bathing, and provide essential sanitation facilities for the village. 3 billion people do not have access to sanitation facilities. Result – 3 million children under age of 5 die each year from water related diseases.

  2. CURRENT SOURCES OF DRINKING WATER: Water Sources – Wells, Springs, Streams, Rain Water. Water Supply - Available, Adequate, Treatable. Quality of the Water – Potable, Nonpotable, High turbidity. Analyze the Water For Contaminants.

  3. FOCUS ON CAUSES OF DISEASE: Phase 1: Acute Health Problems (Short Term Effects). Phase 2: Chronic Diseases (Long Term Effects). Microorganisms – Diarrhea, dysentery, typhoid, cholera. Evaluate health effects of other contaminants that exceed MCLs. Chemical – Methemoglobinemia, Blue-baby syndrome, Nitrates >10 mg/l Turbidity – Carrier of Bacteria, Viruses, and Cysts

  4. REMOVAL OR REDUCTION OF CONTAMINANTS • Prevention and Treatment • Prevention of contamination, less expensive than treatment. • Desirable Characteristics of Water Treatment System • Simple • Low cost • Utilize local resources • Low maintenance

  5. Treatment Technologies Available • Turbidity Reduction • Filtration - Using sand or other available materials • Destroying Microorganisms • Disinfection – Chlorination, Ultraviolet Radiation (UV) • Reduction of Chemical Contaminants • Reduce nitrates by ion exchange • Construct Latrines for Sanitation • Training for Maintenance and Water Testing

  6. IMPLEMENTATION - COLLABORATION OF AVAILABLE RESOURCES Water For People Water For People – Canada Projects Rotary International U N Agencies Task Force Safe Water Plus Project
