Why is the water quality so low in Mexico?

    The main problem with water quality in Mexico lies with the supply of the water, not pollution.  Mexican water is treated for polluted at a central decontamination center before being pumped into homes and businesses.  But because water in Mexico is scarce, it is only pumped into each part of the city for a couple of hours a day.  Each structure in Mexico is built with a large cistern in the basement which fills up while this water is pumped.  Each house is also built with a water tank in the roof, which supplies the water pressure for it to pump out of faucets.  Between the cistern and the tank, the water stays stagnant for up to 22 hours a day, which allows for bacteria.
