Investigation of Küçüksu wastewater collection using smart and sustainable applications

Abstract

Infrastructure is one of the biggest problems of today. Irregular investments, inaccurate population estimates, and unplanned infrastructure are one of the leading problems, especially in developing countries. Although ISKI has focused on infrastructure investments in Istanbul in recent years, all infrastructure constructions are carried out by international standards. Istanbul is an ancient city. There are areas where sewer lines are insufficient, compound, and defected. Istanbul has been exposed to a wave of immigration since the 1960s, and all population projections for the city have been mostly inadequate. This situation has spread to the city's infrastructure, and there are problems with wastewater lines in various regions. In this context, a hydraulic investigation was carried out for the 2021 population of the wastewater collector line, which serves 5527.8 hectares of land going to the Küçüksu pre-treatment plant. As a result of the investigation, it was determined that the line was insufficient, and a new wastewater collector line was designed, which is planned to serve until 2071. For the design, four population estimation methods were examined, and hydraulic design was made by Province Bank method since it performed best in the historical period. A new hydraulic design has been made using Urbano software. The designed collector line was also added to the designed online map using ArcGIS and classified according to fullness rates. The designed online map can be used as a template for decision makers for their city development plans since pipe size and capacity calculations are based on estimated populations at certain years. Moreover, the online system can be opened for public and real estate sector for their planning, assessment and feedback. In addition, the design for the year 2071 was designed to adapt to the requirements of the modern world. In this context, BIM and GIS integration was made for the line, and all the line details were revealed. A base has been created for future studies. Wastewater design was also examined within the scope of the sustainable goals of the United Nations, and intersecting targets were determined within the 17 targets. In many aspects, the hydraulically designed collector line in our study directly coincides with the SDG 3 Good Health and Well – Being, SDG 6 Clean Water and Sanitation, SDG 9 Industry, Innovation and Infrastructure, SDG 11 Sustainable Cities and Communities. This study for the Küçüksu wastewater collector line basin can be strengthened with SCADA systems in the future to provide instant data display. At the same time, this study can be applied to other basins in the future so that more participatory, smart, and sustainable lines can be designed.
