Domestic waste water is waste that comes from the activities of everyday human life related to water usage. Disposal of domestic wastewater without a treatment process will result in pollution of the sources of raw water for drinking water, both surface water (river, lake or situ) and ground water. Wastewater management consists of treating on-site wastewater on an individual basis by providing wastewater treatment tanks or septic tanks and off-site sewage systems carried out collectively or communally through sewerage collection channels and then processed in Wastewater Treatment Plant (WWTP). Some obstacles in the centralized management of domestic wastewater systems, among others, are due to the legislation that does not yet support, the lack of community participation, highly cost in financial factors and also weak technology aspects. The construction of the WWTP unit uses a large amount of funds, so it is unfortunate if it cannot be utilized according to its function. In order to avoid all types of failures related to the non-operation of WWTP, failure analysis can be done. This analysis is expected to be an effort to support the functioning of the Central Domestic Wastewater Management System (SPALD-T) in a sustainable manner. The risk modeling that can be used is Fishbone Analysis and Failure Mode Effect Analysis (FMEA). Failure Mode Effect Analysis (FMEA) is a powerful method for identifying risks. FMEA is implemented to identify potential forms of failure, determine their impact on production and identify actions to reduce failure. The results of failure risk analysis using Fishbone Analysis and FMEA obtained 19 risks and the highest priority failure risks for the sustainability of the Centralized Domestic Waste Management System, namely: (i) maintenance of WWTP buildings, (ii) HR capacity, (iii) payment of contributions and subsidies for regional government funding . In order to minimize failures in the Central Domestic Wastewater Management System, it is necessary to (i) make the Standard Operating Procedure (SOP) for main building maintenance (IPAL), (ii) periodically clean and maintain the WWTP building, (iii) participate in System management training Centralized Domestic Waste Water Management and (iv) evaluation of financial aspects in the context of operational efficiency and maintenance of Centralized Domestic Waste Water Management Systems.
