Abstract
In this study, the potential utilization of sediments deposited in pluvial sanitation systems for engineering applications was investigated using the pluvial sub-basin occupied by the town of Puente Aranda for residential, commercial, and industrial land use in Bogotá city as a case study. The sediment samples were collected at different locations during three different climatic seasons to assess their physical and chemical characteristics. All samples contained more than 70% silt. The highest content ruthenium oxide, phosphorus oxide, potassium oxide, and titanium oxide corresponded with residential land use. Silica and calcium oxide dominate in areas of commercial land use. The results of this study demonstrate that sewer sediments can be used to manufacture Portland cement and pozzolans; however, the addition of calcium carbonate is necessary to increase the lime content in the extracted solids.
