Mexican national water authority Conagua plans to invest 876mn pesos (US$71.9mn) in the construction of wastewater treatment plants and other works to clean up the Amecameca river in Mexico state (Edomex), according to a release.
Work under the authority's Amecameca river cleanup program includes treating wastewater in the river basin for reuse in local agriculture.
The first stage of work will involve construction of intakes and new water treatment plants to service ten municipalities located along the river basin. Conagua will invest 276mn pesos in this first phase, according to the release.
Wastewater generated in Chalco, Valle de Chalco and Ixtapaluca will be treated at a new 500l/s treatment plant that will be built at a cost of 600mn pesos. Additional funds will be required for pumping infrastructure and the purchase of land.
Reuse of the wastewater will reduce overuse of the area's aquifers and the consequential land subsidence, which affects local housing and drainage systems, said Conagua director José Luis Luege.
