Corruption and insufficient resources, both technical and financial, are hindering the development of adequate wastewater treatment in Mexico, environmental law academy AMDA chairman Ramón Ojeda said. “The Mexican wastewater treatment experience is one of the biggest failures in Latin America. Currently, there is not one public or private water treatment plant that is working 100% correctly – in the entire country,” Ojeda said. “The culprit is corruption, which has deceived state and municipal authorities”.
Ojeda said authorities have built several facilities, but they are not enough to guarantee the adequate sanitation of water resources. “Authorities are unable to decide the kind of facility that needs to be installed, resulting in under-investment in the area. Meanwhile, big commissions are offered to the private sector to treat water, but these private facilities do not process the water adequately,” he said. “As a result, the water quality is practically the same after treatment, but private operators continue to charge. The public sector debt [from financing these projects] mounts up and the quality of water does not change,” Ojeda argued. [T]he situation is especially serious in Morelos and Puebla states, where large quantities of water resources are contaminated with oils, detergents, organic materials and even industrial residues, [he said].
In July , Mexican President Felipe Calderón launched a [2.2bn pesos (US$219mn)] national program to stimulate the construction and operation of wastewater treatment plants. [...] Of this total, 700mn pesos is to be destined to construction and rehabilitation, and 1.5bn pesos to operating and maintenance of treatment plants.
[...] In Mexico, only a little over 30% of wastewater is currently treated, in spite of the nearly 200 treatment plants that exist nationwide.
