Abstract

This study aims to discover the obstacles and provide recommendations on the technical and institutional aspects of the chosen communal WWTP. The methods used in this study were field survey and questionnaire. the data were analyzed using quantitative, qualitative, and SWOT analysis. There are 11 out of 13 communal WWTPs that do not work optimally. The technical obstacle encountered in the operation of the chosen communal WWTPs is the huge building capacity that does not meet the criteria of HRT design. The recommendations for the technical problem include lowering the water level and reducing the number of baffles in communal WWTP. The obstacle faced in the operation of chosen communal WWTPs in terms of institutional and community participation aspects is that the maintenance is only known by few people. The recommendation for the aspects of institutional and community participation is for KPP to arrange a socialization on the maintenance of communal WWTP based on its maintenance module.
