The purpose of this activity was to provide an assessment of the safety of Yerevan's drinking water supply and sewage disposal system and to make recommendations for correcting any immediate health hazards (emergency actions). The consultant team was also asked to make recommendations for permanently correcting deficiencies (longer-term actions). In addition, the team made recommendations for the water and sewer systems serving other areas of Armenia. The assessment examined municipal water supply systems; municipal sewage collection, treatment, and disposal; health education/public information; household-level water and sanitation use, behaviors, and systems; and municipal solid waste.
