Natural disasters, community clashes, armed conflict, and other related issues have led to the loss of lives and properties in Nigeria, this has generated a large number of internally displace persons across the country, especially in the northern part of Nigeria and also the middle belt region. These camps usually have poor living conditions relating to water, sanitation, and hygiene (WASH). These poor living conditions have led to the inadequate supplies of facilities and equipment as relating to the issues of water, sanitation, and hygiene. This study, therefore, seeks to assess the state of water, sanitation, and hygiene of Heipang IDP camp in Plateau State, Nigeria. Durkheim‟s (1917) theory of change served as the framework for analysis. The case study research design was adopted for the study and the RCC Heipang IDP camp was selected due to the massive influx of displaced persons to the camp and the population of the camp which is officially pegged at 3,026 people. A total number of 7 In-Depth Interviews (IDI) and 3 Key Informant Interviews (KII) were carried out on purposively selected respondents. The respondents included 7 members of the camp executives who are representative of the IDPs as well as 3 camp officials. Furthermore, two Focus Group Discussion (FGD) was conducted with camp inhabitants. The FGD population was evenly distributed to accommodate 6 men in the first FGD and 6 women in the second FGD. To deepen the discuss, non-participant observation was carried out by the researchers. Thus, a cursory observation of WASH facilities and interventions in the Heipang camp was carried out by the researcher. Data gathered from the field was translated, categorised and themed in line with the study objective. Findings show that the state of WASH facilities in the camp is below the acceptable standard of living as water is inadequate and there are insufficient sanitation and hygiene facilities. These harm the health of the IDPs and poses threat to their human security challenges bordering around personal security, health security, environmental security, and community security. Therefore, stakeholders such as the Federal Government, State Government, NEMA, SEMA, INGOs, NGOs, and other individuals should prioritise the provision of WASH facilities, in line with global best practices, to improve the living condition of the IDPs while sanitation and hygiene sensitization campaign should be calibrated .
