Aid agencies are warning that their ability to keep delivering basic services in earthquake-stricken Haiti is being stretched to the limit.
The Red Cross says aid agencies are still providing most of the clean water and toilet facilities six months after the devastating quake, which killed up to 230,000 people and left a million homeless.
Prime Minister Rene Preval has said his government does not have enough money to run and rebuild the country, the BBC reports.
The 7.0-magnitude earthquake struck the area around the capital, Port-au-Prince on 12 January, flattening homes and buildings over a wide area.
Most of those who lost their homes are still living in temporary encampments.
"We are all stretched to our capacity and simply containing a critical situation, rather than solving it," says Alastair Burnett, an operations manager with the British Red Cross.
'Staggering gap' between promises and reality
Reconstruction has been slow because of the scale of the disaster and a shortfall in humanitarian funding for Haiti.
"From this moment on, sanitation must be integrated into wider plans to rebuild Haiti and long-term solutions must be found," Mr Burnett said in a report released on Thursday by the International Federation of Red Cross and Red Crescent Societies.
Charity Medicins Sans Frontieres (MSF) has warned that frustration is growing among Haitians over the "dire reality" of their living conditions.
"There is a staggering gap between the enthusiasm and promises for aiding the victims of the earthquake in the early weeks, and the dire reality on the ground after half a year," says MSF's head of mission in Haiti.
One bright spot, however, MSF says, is that the provision of medical services to the majority of Haitians is better than before the earthquake.
