Mexico's national water authority Conagua plans to spend over 1tn pesos (US$85.3bn) in the next 20 years under its 2030 water plan, the authority said in a release.
This amount represents an annual investment of 23bn pesos and is double the previous government's spending on water and sanitation, according to Conagua director José Luis Luege.
The 2030 plan, presented by President Calderón in March 2010, focuses on cleaning rivers, stabilizing water basins, flood relief, and reaching universal potable water coverage.
Projects include the Atotonilco wastewater treatment plant, preservation work for the México valley, the Querétaro II potable water pipeline, the El Realito dam, suburban sanitation work in Guadalajara and Jalisco's El Zapotillo dam, among others.
Of the country's 635 aquifers in the country, 101 are currently overused. The average availability of water per capita has decreased by four times in the past 60 years, according to Luege.
