The 115mn peso (US$6.16mn) contract was granted to the company by federal water authority Conagua on October 12, reported Reforma.

The Contracorriente PTAR was built in 1987 with the objective of sustaining water levels in the Nabor Carrillo lake and contributing to the protection of Texcoco lake. Operations at the PTAR have been halted since 2003 due to a structural fault.

Aqualia will be in charge of building and equipping a new treatment system at the plant that can process at least 120 liters of wastewater per second, as well as laying a pipeline to distribute water to the future airport's construction site.

Aqualia put in the lowest offer for the tender, according to Reforma, and will now have 11 months to complete the works, in addition to a 90-day trial operation period before turning the plant over to Conagua.

The Mexican government is carrying out various waterworks to improve infrastructure in the area in which Mexico City's future airport is being constructed.
