Mexico's environment ministry, Semarnat, has invested 27.2bn pesos (US$2.20bn) in water projects during 2011, according to a release.
National water commission Conagua channeled 60.8% of the investment to potable water, sanitation and drainage projects, 27.6% to the operation and development of irrigation infrastructure and 11.6% towards flood prevention.
Potable water coverage has risen to 91.3% since the start of President Felipe Calderón's administration, while wastewater collection coverage has improved to reach 89.9% of the country.
Standout projects include repairs to line II of the federal district's Cutzamala potable water system at a cost of 50mn pesos and extension of the drainage network, including ongoing works on major drainage tunnels in the capital.
During 2011, Semarnat has also invested 540mn pesos on waste management projects across 24 states, including installation of 36 sanitary landfills across the country.
