Mexico) Data refers to wastewater collected in the public sewer network. The wastewater that does not reach the public sewer is not included.

Costa Rica) Total wastewater generated is estimated by multiplying the volume of water billed to users by 0.75. Break in series in 2015 due to the use of more complete information (data is therefore not comparable to previous years). WWTP effluents do not include runoff rainwater, since the mixing of these 2 types of waters is prohibited. During the period 2008 to 2014, only the generation and treatment of waste water from users of the main public water supply operators (ISIC 36) was reported.
