Urban water management in Monterrey, Mexico
In 1995 the population of the San Juan watershed was 5m inhabitants, of which approximately 4m 
were in Metro Monterrey (MAM) and the population is expected to increase to 8.4m inhabitants by 2020. The population of MAM is located within 360 km across nine municipalities (Apodaca, Garcia, Escobedo, Guadalupe, Juarez, Monterrey, San Nicolas, Santa Catarina and San Pedro). Taking discharge and aquifer recharge, current population and average hydrology into account, the watershed possesses a water availability of 484 m per inhabitant per year and would be reduced to 230 m per inhabitant per year by the year 2020. The watershed therefore ranks amongst the poorest regions in regards to per capita water availability with countries such as Syria, Israel, and Saudi Arabia. Per capita water use estimates, including domestic, commercial, municipal, and industrial supplies, approach 290 liters per day per inhabitant for MAM. More specifically, the MAM receives 60% of their water supply from surface water while the remaining 40% comes from an extensive network of groundwater wells.
