WHO's Guidance on Water Sanitization

  • Conventional, centralized water treatment methods that use filtration and disinfection should inactivate the COVID-19 virus.

  • For effective centralized disinfection, there should be a residual concentration of free chlorine of ≥0.5 mg/L after at least 30 minutes of contact time at pH <8.0. 12 A chlorine residual should be maintained throughout the distribution system.

  • In places where centralized water treatment and safe piped water supplies are not available, a number of household water treatment technologies are effective in removing or destroying viruses, including boiling or using high-performing ultrafiltration or nanomembrane filters, solar irradiation and, in non-turbid waters, UV irradiation and appropriately dosed free chlorine.
