It integrates high-resolution in-sewer measurements of flow rate, water level, flow velocity and water quality parametres (COD, TSS, temperature), complemented by laboratory analyses of discrete grab samples. Water quality parametres were monitored using an in situ UV\/VIS spectrometer installed on a floating pontoon. Additional locally calibrated COD values derived from laboratory measurements are included. The in-sewer data were acquired at 1 or 3 min intervals depending on flow conditions. Flow rates, water levels and overflow discharges were monitored using radar and ultrasonic sensors. Three nearby tipping-bucket rain gauges provided time-stamped precipitation increments, enabling the detailed reconstruction of wet-weather dynamics. A hydrodynamic SWMM model of the catchment, including geospatial information and dry-weather calibration, is included to support modelling applications. This combination of long-term measurements and a calibrated hydrodynamic model supports the development, testing and validation of process-based, statistical or data-driven approaches for simulating combined sewer system behaviour and pollutant dynamics.<\/jats:p>","DOI":"10.3390\/data11030045","type":"journal-article","created":{"date-parts":[[2026,2,26]],"date-time":"2026-02-26T13:58:03Z","timestamp":1772114283000},"page":"45","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Dataset on Continuous Sewer Hydraulic and Pollutant Concentration Observations from 2008 to 2011 Including Precipitation Data, Laboratory Analysis and a Hydrodynamic Model"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8101-2163","authenticated-orcid":false,"given":"Markus","family":"Pichler","sequence":"first","affiliation":[{"name":"Institute of Urban Water Management and Landscape Water Engineering, Graz University of Technology, 8010 Graz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Hofer","sequence":"additional","affiliation":[{"name":"Institute of Urban Water Management and Landscape Water Engineering, Graz University of Technology, 8010 Graz, Austria"},{"name":"IKK Group GmbH, 8020 Graz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1087-4620","authenticated-orcid":false,"given":"Valentin","family":"Gamerith","sequence":"additional","affiliation":[{"name":"Institute of Urban Water Management and Landscape Water Engineering, Graz University of Technology, 8010 Graz, Austria"},{"name":"Department 15 Energy, Housing, Technology, Office of the Styrian Provincial Government, 8010 Graz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9153-1373","authenticated-orcid":false,"given":"G\u00fcnter","family":"Gruber","sequence":"additional","affiliation":[{"name":"Institute of Urban Water Management and Landscape Water Engineering, Graz University of Technology, 8010 Graz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,26]]},"reference":[{"key":"ref_1","unstructured":"Hochedlinger, M.
