Mexico's federal district (DF) government plans to concession two wastewater treatment plants, according to information published in the official gazette.
One of the plants, located in the southern suburb of Coyoacán, is currently being operated by city water utility SACM following the expiration of the previous concession in 2006.
The operation, maintenance and administration of the 300l/s plant will be concessioned to allow the utility to concentrate its efforts on other projects.
The second plant to be concessioned is located in Santa Fe district and has a capacity of 280l/s. The plant is currently treating 180l/s and one of the requirements of the concession will be to increase operating capacity.
The plant has been renovated several times, most recently in 2009, and the new concession holder will be expected to "optimize operation, conserve the installations and increase the amount of treated water."
