Nevertheless, rationing of water and interrupted sanitation are ordinary incidents in small towns and rural areas. [20] Drinking water quality.
The ratio of sanitation to water tariffs of almost 1:1 is very high for Latin America and close to the ratio of the actual cost of the two services, while in most other Latin American countries sewer tariffs remain much lower than water tariffs. Water and sewer tariffs vary substantially between cities.
It is estimated that 45% of the water produced is not counted due to physical and commercial losses, which is higher than the other 40% average of Water and sanitation in Latin America.
