Key Learning Points

• The importance of
• Considering potential health risks such as
  malaria and diarrhoeal diseases
• Good coordination with local authorities
  encouraged to lead the response, where
  appropriate
• Consultation with the affected community
• There is a sequence in carrying out rapid
  assessment of flood-damaged municipal water
  treatment plants and distribution systems
• There are immediate sanitation considerations,
  especially excreta disposal. Hygiene Promotion
  and community mobilisation is a key element.
