Abstract
Development Unit (UP) I Rungkut is one of the areas in Surabaya that has a high risk of sanitation problems. The causes are environmental problems arising from the disposal of domestic waste which is directly discharged into drainage channels. Therefore, the Development Unit (UP) I Rungkut Surabaya City designed a Wastewater Distribution System and a Wastewater Treatment Plant (WWTP). In this study, a shallow sewer type wastewater distribution system was used because it is suitable for areas of high population density and gently sloping ground elevations. In the WWTP, several alternative technologies are used, such as the Bar Screen, Equalization Tank, Flotation Tank & Oil Settlement Tank, Mixing Tank (Coagulation-Sedimentation Tank), Food Chain Reactor, Final Clarifier, and Sludge Drying Beds. The planning area is divided into 5 service blocks with a total population of 24,405 people. The results of the study of the technical aspects, are used WWTP with the main processing using the Food Chain Reactor unit. The planning results show that HDPE pipes with a diameter of 355-500 mm are used in the distribution system. The required investment budget is Rp. 87,832,528,386.00. The budget for operating and maintenance costs is Rp. 4,000.00/House Connection (SR) every month.
