Agua de San Agustin Etla

The villagers from my home away from home, San Agustin Etla, continue to keep the water valves closed that feed the western part of the city. If you wish, look at this map to see the locations and distances involved. The people are right to protest how their land and surrounding environment are used or abused, as it is in this case. It is, however, pissing a lot of people off. As always, there are numerous solutions, but only one or two that seem just and right. What are the odds that people will end up doing what is best for the land and themselves?
