Resumen:

Cities must provide services and resources in optimal conditions for their inhabitants to live in harmony. The primal ones are the lifelines systems that furnish services such as water, energy, transportation, etc. If the territory is heavy populated these systems are composed by complex networks that comprise extended distances hence making them more vulnerable to many different kind of risks, particularly the natural ones. The water system is one of the most fundamental lifelines and it is often subjected to natural hazards, especially flooding and earthquakes. Mexico City, being one of the most populated cities in the world requires a colossal water network that is often subjected to seismic forces. Moreover, the complex soil conditions in the basin and the problem of regional subsidence, make the system more vulnerable. This paper presents a brief background of the water system in the city and its damage during the 1985 Michoacan Earthquake and the 2017 Puebla-Morelos Earthquake. It also compiles the measures taken after these earthquakes to restore the system. The extent of damage and the geotechnical conditions are described. The fundamental of seismic vulnerability and some countermeasures that can be implemented to turn the Mexico City water network into a more resilient system are discussed, as well the challenges that large urban water supply systems have to deal to overcome their vulnerability to seismic hazards and increase its resilience.
