Abstract: According to microbiological pollution pattern, distance between infiltration against clean water source is at least 10 m in order to prevent water or soil pollution. Qualifying distance requirements according to pollution pattern is contrary with land ownership in urban areas which on average; urban people have narrow land. This research aims to analyse the effectiveness of infiltration in tripikon type and spiral type based on the decrease of BOD level, TSS level, Ammonia and Coliform level. This research was an experimental research by using one group pre and post-test design. The sample in this research was household liquid waste and measured the decrease of BOD level, TSS level, Ammonia level and Coliform level as an indication of pollution minimization. The result, infiltration in spiral type was more effective in reducing BOD, TSS, Ammonia and MPN Coliform parameters rather than infiltration in tripikon type. When it was compared to septic tank outlets, the infiltration in either tripikon type or spiral type could reduce the level of BOD, TSS and MPN Coliform but could not reduce ammonia parameters. This was occurred because system that was occurred in infiltration was anaerobic, thus, the ammonia levels increased after being through the infiltration.
