Abstract

New residence of local fisherman will be built in Puger Kulon Village in the District of Puger, Jember. This area is quite densely populated with a density of 376 inhabitants/ha The physical condition of this area is sandy soil, the spaces between houses are about 1-2 m, it is located near the river, approximately 200-300 m from the beach, and 1000 houses is being planned to be build on an area of 34.71 ha. On site waste water system (septic tank) is not suitable to be used in this area, because infiltration from the septic tank can easily penetrate into the soil and pollute ground water and rivers in this area. Three alternatives of wastewater pipe networks were scenario 1, scenario 2, scenario 3 then most effective and efficiencent will be selected pipeline scenario. Scenario number 1 was selected as the most effective and efficient shallow sewer pipeline system because scenario 1 has an average velocity of 0.6229 m/s, the smallest total energy loss of 0.279488, efficiency in pipe length of 47.3 % and ease of maintenance when clogging occur. The diameter of pipes in the pipeline is 75 mm. The smallest dimension for the pipelines connected to communal tanks is 100 mm, where as the biggest dimension is 250 mm. The shallow sewer system requires water as much as 0.001988 m3/s for flushing maintenance.
