Faeces Waste Treatment Design in Household with Narrow Land Area

Recently, the distance of wastewater infiltration from septic tank and clean water source is not suitable because developers build houses with narrow land area so that the house price is affordable. This research aimed at analyzing faeces waste treatment design in household with narrow land area, using experimental design. The variables were Coliform bacteria and turbidity of wastewater that passed the treatment design in the distance of 0, 5, 7, 9, 11, and 13 meters. The obtained data was analyzed using Anova. Domestic wastewater treatment design with narrow land area needed at least 3 m². It could reduce Coliform bacteria until 13 meters in 74 colony/100 ml, meanwhile, the turbidity in the distance of 0 meter was qualified into the determined requirement with the average of 19.49 NTU. It could reduce either Coliform bacteria or turbidity significantly in every distance and in the distance of 13 meters, the percentage of decrease was 88.42% for Coliform bacteria, meanwhile, 98.14% was for turbidity.
