Mexico's Jalisco state water authority CEA has spent 690mn pesos (US$57.6mn) on building and repairing wastewater treatment plants since 2006.
A total of 50 new plants were built in 37 municipalities, benefiting some 372,955 residents, local daily Informador reported.
There are currently 258 wastewater treatment plants in the state, though some municipalities are not able to operate plants at full capacity due to the facilities' extensive energy use.
CEA has invested some 52mn pesos to address this issue, according to the report.
Some 26 treatment plants in the state are currently not in condition to operate, and four others are being built and will benefit municipalities Teuchitlán, Jesús María, Tlajomulco and Unión de Tula.
