In response to the challenges outlined above, the Federal Government, the State of Mexico and the Federal District initiated a US$2.8 billion Water Sustainability Program in 2007. Additionally water price was substantially reduced for low consumption users since 1996.[16]. The volumes stored in the system are dependent on previous years’ rainfall. [6] All works on the tunnel system are expected to be completed in September 2012, at an expected cost of MXP 13 billion (approx.

[6], Leaks in the distribution system are a major cause of concern for drinking water quality. Drought conditions now cover 85% of Mexico, and residents of the nation's central region said Thursday that lakes and reservoirs are simply drying up, including the … We are primarily working with associations of microfinance institutions in Mexico. However, this layer has fractured due to land subsidence. Furthermore, it is estimated than 1/3 of the water connections in the region are informal and therefore this consumption is not billed. Both plans aim at reducing non-revenue water. Cecilia Tortajada: Water Management in Mexico City Metropolitan Area, in: International Journal of Water Resources Development, Vol. [9] Currently, the metropolitan area generates 40 m3/s of wastewater; however capacity is only built to handle 10 m3/s. These measures together, if successful, would reduce groundwater abstraction in Greater Mexico by 10% and the overdraft by 25%. Papers included in this volume describe the groundwater resources of Mexico's Yucatan Peninsula, approaches to managing groundwater in Mexico and governmental and scientific institutions concerned with water resources.

Crops to be grown using wastewater are restricted to crops not eaten raw, but these restrictions are difficult to enforce and farmers also grow vegetables using wastewater. [27], Untreated wastewater is also disposed of in surrounding rivers that run to the sea, but this runoff water polluted with untreated waste water is also used for irrigation as farmers have found that the high concentration of nitrogen and phosphorus nutrients effectively fertilize their crops and increase crop yields. Under the contracts the number of metered connections increased from virtually none in 1994 to up to 1,264,500 in 2002, reaching more than 90% of all users. [6] Recharge of the aquifer is about 31.6 m3/s compared to abstraction of 59.5 m3/s, resulting in an overdraft of about 28 m3/s. About.
