This paper assessed WASH Facility interventions in Anambra State Nigeria, in other to evaluate operational status and identify issues affecting its sustainability. The study was conducted in 13 communities, from Ndemili North, Anambra East and Nnewi Local Government Areas. A mix of purposive and random sampling techniques were adopted for this study. A total of 17 facilities were purposively identified; 13 water supply and 4 toilet facilities, while random sampling was used to select 650 respondents. Data collection was done using structured questionnaire, focus group discussions and physical observations. The data collected were analysed using Likert scale rating of 1 – 5, averages, tables and charts. The findings revealed that 42% and 20% of water supply and sanitation facilities respectively were functional in the study area, meanwhile 58% and 80% were not functional respectively. Further analysis on water supply facility functionality indicators rated on Likert scale showed that 30% were in good conditions, 20% were neither in good or deplorable condition and 50% were in deplorable condition. Toilet facility functionality showed that 17% were in a very good conditions, 33% were neither in good nor in deplorable condition and 50% were deplorable condition. Evaluation of sustainability of the WASH facilities interventions revealed that only 21% of the communities have skilled artisans who can carry out minor maintenance in the event of break down. About 43% of the community members do not know how to communicate facility challenge to appropriate authorities, while 93% of the communities do not have any system of water tariff collection to provide fund for minor maintenance. Also, 86% of the communities, do not have functional WASHCom in place which are supposed to carry out monitoring activities, provide inventory of facilities with challenges and carry out awareness campaign. The analysis revealed huge gap in the WASH Facility interventions management and therefore recommended that existing WASH management practices be strengthened by providing regular training of skilled artisans, creatiing more awareness in communities, creating a self-sustaining financial system and strengthening WASHComs.
