Bertin is the biggest slum in the town of Carrefour and is located 5 miles west of the center of Port-au-Prince. The neighborhood is very poor and ill-serviced and has an estimated population of over 400,000 people. International Action installed 10 chlorinators between 2006 and 2007 and has been working with local water board members to maintain chlorinators and distribute de-worming pills.

Last March International Action visited a school with no community water distribution kiosks access causing the students and teachers to suffer. International Action installed a 150-gallon water tank to provide water.
