Treatment Plant (FSTP) of Keputih in Surabaya City. The district has an area of
23.66 km2 with a population of 110.726 people. Although the sub-district has a low population density, based on government’s data in 2020, it shows that Sukolilo as the highest faecal desludging services in Surabaya. This is due to the proximity of the suction and disposal locations. So that the costs incurred are relatively affordable for the community. It is known that Scheduled Sludge Service (SFSS) system still not implemented. Meanwhile, the plant of Keputih still has an idle capacity of 75%. This study aims to see the of the Sukolilo District as the initial location for the implementation of the SFSS program in the city of Surabaya.
