An escalation of violence between rival gangs in Martissant and Grand Ravine has led the IAWater team to reevaluate where they are installing chlorinators. More than forty people were killed and twenty houses burned in ongoing gang fighting. The team has decided to install four chlorinators in Trousable until the security situation in other areas improves. It has also identified several sites for installations: two in the hills above Pétion-ville, one in Delmas 33, one in Cite L'eternal and several in Cité Soleil.
One of the displaced-persons camps in Port-au-Prince, called Martissant 2A, has developed into a sprawling shantytown of 35,000 people and also gained the nickname “the lawless zone,” due to how under-served its residents are. In July of 2011, DINEPA (the Haitian government’s water agency) undertook the responsibility of building five water stations around the area, with the aid of the International Organization for Migration and the International Red Cross.
