TL;DR: This study represents the first extensive spatiotemporal investigation of water pollution in an endemic typhoid fever setting and implicates highly localized human waste as the major contributor to poor water quality in the Kathmandu Valley.
Journal ArticleDOI
Sewer asset management – state of the art and research needs
Franz Tscheikner-Gratl,Nicolas Caradot,Frédéric Cherqui,João P. Leitão,Mehdi Ahmadi,Jeroen Langeveld,Yves Le Gat,Lisa Scholten,Bardia Roghani,Juan Pablo Rodríguez,Mathieu Lepot,Bram Stegeman,Anna Heinrichsen,Ingo Kropp,Karsten Kerres,Maria do Céu Almeida,Peter M. Bach,Matthew Moy de Vitry,Alfeu Sá Marques,Nuno Simoes,Pascale Rouault,Nathalie Hernández,Andrés Torres,Caty Werey,Bénédicte Rulleau,Francois Clemens +25 more
TL;DR: Sewer asset management gained momentum and importance in recent years due to economic considerations, since infrastructure maintenance and rehabilitation directly represent major investments as discussed by the authors. But it is still a relatively new area.
Journal ArticleDOI
Partial Least Squares local calibration of a UV–visible spectrometer used for in situ measurements of COD and TSS concentrations in urban drainage systems
TL;DR: A method was applied to estimate TSS or COD concentrations at the inlet of a storage-settling tank in a stormwater separate sewer system, and compared to three other calibration methods used either for turbidity meters or UV-visible spectrometers.
Journal ArticleDOI
Calibration of UV/Vis spectrophotometers: A review and comparison of different methods to estimate TSS and total and dissolved COD concentrations in sewers, WWTPs and rivers.
Mathieu Lepot,Andrés Torres,Thomas Franz Hofer,Nicolas Caradot,Günter Gruber,Jean-Baptiste Aubin,Jean-Luc Bertrand-Krajewski +6 more
TL;DR: This collaborative work presents a comparison between five different methods used to monitor water quality in various locations, according to the Kruskal-Wallis test and RMSEs, PLS and SVM seem to be the best methods for concentration estimations.
Journal ArticleDOI
Practical benchmarking of statistical and machine learning models for predicting the condition of sewer pipes in Berlin, Germany
Nicolas Caradot,Mathias Riechel,M. Fesneau,Nathalie Hernández,Andrés Torres,Hauke Sonnenberg,E. Eckert,N. Lengemann,J. Waschnewski,Pascale Rouault +9 more
TL;DR: Developing a set of clearly understandable metrics to assess the performance of sewer deterioration models from an end-user perspective and shows a strong potential for supporting operators in the identification of pipes in critical condition for inspection programs.
