Problematic Approach
Problem
The Savannah of Bogotá has a functional and seismic vulnerability in case of a natural disaster, in which its drinking water supply systems would fail, leaving a large percentage of population affected
Problematic Approach
In case of earthquake
•More than a 40% of the buildings could fail.
• Geophysical and topographical failures would affect the water, energy and communications supply systems. • An integral plan of analysis of technologies has to be improve in institutional accommodations in case of emergency, directed by the Commission of Infrastructure, Mobility and public Utilities.
Objetives
To select commercially available technologies to supply drinking water. • Identification of typologies of institutional accommodations.
• Analysis of different scenarios proposed for an eventual case of emergency • Assessment of technologies and configurations of water production systems according to the criteria evaluated.

Drinking Water Emergencies
Normal situations: Wide range of parameters. Emergency: Parameters are readjusted Water without microbial risk should be guaranteed Minimum quantity of required water Easy accessibility Continuity of service Water treatment systems: minimum number of chemical products for its operation
