TEPATEPEC, Mexico — For more than 100 years, most of what gets flushed down Mexico City’s toilets has resurfaced two hours to the north in the rivers and reservoirs of the rural Mezquital Valley. A massive new water treatment plant is about to change this.
But rather than welcoming the prospect of cleaner water, angry farmers are demanding the government honor an 1895 presidential decree granting them the right to the capital’s untreated sewage, which they see as fertilizer-rich, if foul, irrigation water.
It’s a standoff that pits public health concerns — not just for valley residents but for the Mexicans elsewhere who eat the crops — against fears that family farms will go under if they lose access to the raw sewage after the $530 million Atotonilco plant in Hidalgo state, billed as the largest of its kind in Latin America, goes online.
