Access to piped water supply in Brazil stood at 77% and access to improved sanitation also at 77% in 2006. Coverage is significantly higher in urban areas, where 84% of the Brazilian population live. Urban coverage is 96% for water and 83% for improved sanitation, including 53% access to sewerage, the remainder being accounted for by on-site sanitation. Coverage in rural areas, where 16% of Brazil’s population lives, is much lower. It stands at 57% for improved water supply and only 37% for improved sanitation. Geographically coverage is lowest in the country’s poorest regions: particularly in predominantly rural North, Northeast, and Center-West.
Filling the gaps in drinking water distribution infrastructure, with atmospheric water vapour processors (atmospheric water generators) can be a useful alternative. The water-from-air resource is plentiful in much of Brazil as shown by the Water-from-Air Resource (WFAR) annual indices for nine Brazilian sites tabulated here:
Excellent: Index is greater than or equal to 1.00
Good: Index range 0.76 to 0.99
Fair: Index range 0.51 to 0.75
Poor: Index range is less than or equal to 0.50
Water-from-Air Resource charts are now available for nine Brazilian cities: Belem, Goias, Iguatu, Manaus, Parana, Porto Alegre, Recife, Rio de Janeiro, and Sena Madureira. The charts show the monthly variability in the water-from-air resource.
