Isolated areas" study: Identify households in need of water, not connected to the network

As part of the PROTEGE programme, the government of New Caledonia wished to Identify off-grid residential areas that are experiencing water shortages, to quantify the problem of water shortage in New Caledonia.

In New Caledonia, the population’s water supply is managed by the municipalities. They have no obligation to connect a home if it is not connected to a distribution network if the location of the house(s) is not consistent with their urbanization objectives. In New Caledonia, many households manage their water supply.  However, lack of water is considered a strong health risk. Access to water is a health determinant.

The intermediate results of the study show that in 2022, out of 26 communes, i.e. about 30% of the inhabitants and households of New Caledonia :

-93.4% of households are supplied with water by communal services;

-5.7% of households are supplied privately (catchments, boreholes, etc. on private property);

-0.9 of households are in a water shortage situation.


Among these people in a water shortage situation:

508 inhabitants (0.6% pop for 26 communes) are waiting for an existing water supply project carried out by a commune.

323 inhabitants (0.4 % pop NC for 26 communes) are without a public water supply project.


Finally, the report points out that many actions still need to be taken. These include:

-Finalizing the inventory with the remaining 7 communes;

-Creating support tools;

- Prioritizing the areas of households in a water shortage situation;

 -Evaluating the evolution of the situation throughout New Caledonia;

-Identifying partners to support the projects of municipalities and individuals;

- Reaching the 2019 PEP objective of providing 150 litres of drinking water per day per inhabitant.


A need was identified by the Department of Health and Social Affairs (DASS) of the New Caledonian Government. A study conducted by EAU NC SARL and funded by the European Union through PROTEGE.
