Mexican national water authority Conagua head José Luis Luege has called on the federal district (DF) government to increase its investment in water and wastewater treatment.
The city currently has a 40% physical loss rate along its primary and secondary potable water networks, which means entire reservoirs' worth of water are lost every day, local press reported.
The city is also treating only 6% of its wastewater, despite being obliged to treat all wastewater by a 1996 law.
"The heads of government are turning a blind eye," Luege was quoted as saying, adding that the Mexico valley area has very few wastewater treatment pants and many are not operating at full capacity.
The Conagua head highlighted cities such as Monterrey and Baja California Sur, which currently have 100% wastewater treatment, as examples of responsible water management.
