(author)Ondanks vele verbetermaatregelen staat de waterkwaliteit in de Dommel nog voortdurend onder druk door de effluentlozing vanuit de rwzi en de overstorten in verhouding tot de capaciteit van het ontvangende oppervlaktewater. Naast de Iwelpunten met de zuurstofhuishouding spelen vooral bij overstortsituaties in De Dommel hoge ammoniumpieken, die...journal article 2012

Stanic, N. (author), Langeveld, J.G. (author), Clemens, F.H.L.R. (author)Rioleringsbeheer is een eerste vereiste om het gewenste niveau van functioneren van de riolering te behouden. Welke inspanning op het gebied van rioleringsbeheer nodig is om een bepaald niveau van functioneren te bereiken is onduidelijk, omdat zowel de processen in als de structuur van de rioolstelsels complex zijn. Een belangrijke vraag hierbij...journal article 2012

Boogaard, F.C. (author), Van de Ven, F. (author), Langeveld, J.G. (author), Van de Giesen, N. (author)Stormwaters, flowing into storm sewers, are known to significantly increase the annual pollutant loads entering urban receiving waters and this results in significant degradation of the receiving water quality. Knowledge of the characteristics of stormwater pollution enables urban planners to incorporate the most appropriate stormwater...journal article 2014

Makris, K. (author), Langeveld, J.G. (author), Clemens, F.H.L.R. (author)Polyvinyl chloride (PVC) sewer pipes have operated for decades in a hostile environment, raising concern among sewer managers over the longevity of their drainage systems. Inspection data (CCTV and Panoramo®) reveals that severe defects have already surfaced, yet it is unknown if the material properties of PVC sewers have been affected. In...journal article 2021

Rietveld, M.W.J. (author), Clemens, F.H.L.R. (author), Langeveld, J.G. (author)Runoff (re)mobilises solids and their associated pollutants from streets and transports them via gully pots to the drainage system. As the solids negatively impact the performance of the drainage systems, knowledge on the solids loading in terms of mass and composition is essential. However, monitoring data on the solids loading, in...journal article 2021

Langeveld, J.G. (author), van Daal-Rombouts, P.M.M. (author), Schilperoort, Remy (author), Nopens, Ingmar (author), Flameling, Tony (author), Weijers, Stefan (author)Wastewater treatment plants (WWTP) typically have a service life of several decades. During this service life, external factors, such as changes in the effluent standards or the loading of the WWTP may change, requiring WWTP performance to be optimized. WWTP modelling is widely accepted as a means to assess and optimize WWTP performance. One of...journal article 2017

(author)Gedreven door ontwikkelingen zoals klimaatverandering, verstedelijking en digitalisering zien we in het stedelijk watersysteem steeds vaker oplossingen ‘buiten de buis’. Oplossingen zoals publieke pleinen met een waterbergende functie, polderdaken met een dynamische waterberging, zwembaden verwarmd met warmte uit (afval)water; het zijn allemaal...journal article 2019

Daulat, Shamsuddin (author), Rokstad, Marius Møller (author), Klein-Paste, Alex (author), Langeveld, J.G. (author), Tscheikner-Gratl, Franz (author)The prosperity of urban life is dependent on its infrastructure. Urban underground infrastructure components (assets) are aging and need regular monitoring, maintenance and rehabilitation. These assets are often placed under pavements and in close vicinity to each other. Managing them in a coordinated way is rational considering costs and...journal article 2022

Rietveld, M.W.J. (author), de Rijke, D. (author), Langeveld, J.G. (author), Clemens, F.H.L.R. (author)Urban runoff (re)mobilises solids present on the street surface and transport them to urban drainage systems. The solids reduce the hydraulic capacity of the drainage system due to sedimentation and on the quality of receiving water bodies due to discharges via outfalls and combined sewer overflows (CSOs) of solids and associated pollutants....journal article 2020

Nieuwenhuis, E.M. (author), Cuppen, Eefje (author), Langeveld, J.G. (author), de Bruijn, J.A. (author)Climate change and urbanization, as well as growing environmental and economic concerns, highlight the limitations of traditional wastewater practices and thereby challenge the management of urban water systems. Both in theory and in practice, it has been widely acknowledged that the challenges of the twenty-first century require solutions...journal article 2021

Rietveld, M.W.J. (author), Clemens, F.H.L.R. (author), Langeveld, J.G. (author)Urban runoff remobilises solids and their associated pollutants from urban-built environments and transports them to drainage systems via gully pots. This study presents an extensive monitoring campaign on the solids loading to drainage systems, including 104 gully pots as sampling locations and lasting 2 years. The solids loading is modelled...journal article 2022

(author)The shedding of pathogens by infected humans enables the use of sewage monitoring to conduct wastewater-based epidemiology (WBE). Although most WBE studies use data from large sewage treatment plants, timely data from smaller catchments are needed for targeted public health action.

van der Werf, Job (author), Kapelan, Z. (author), Langeveld, J.G. (author)To evaluate the performance of Real Time Control (RTC) of urban drainage systems (UDS) a comparison is made with the pre-RTC situation, making the RTC performance dependent on the functioning of the UDS prior to implementation. To standardise things, a generalised baseline is formulated here as the operation with optimal static settings of the...journal article 2021

Vollaers, Vita (author), Nieuwenhuis, E.M. (author), van de Ven, F.H.M. (author), Langeveld, J.G. (author)Despite being widely implemented, sustainable urban drainage systems (SUDS) do not always function flawlessly. While SUDS have been tested extensively and seem to perform well on a laboratory or pilot scale, practitioners’ experience is different: failures in SUDS occur regularly in practice, resulting in malfunctioning systems, water...journal article 2021

(author)This article explores the potential of vibro-acoustics to detect physical ageing of plastic pipes. For this purpose, two different topics are combined: the ability of vibro-acoustics to estimate the storage modulus of a plastic pipe, and the sensitivity of the estimated storage modulus to changes due to ageing. Concerning the first topic, a...journal article 2023

Meijer, D.H. (author), Korving, J.L. (author), Langeveld, J.G. (author), Clemens-Meyer, François (author)Urban drainage systems are composed of subsystems. The ratio of the storage and discharge capacities of the subsystems determines the performance. The performance of the urban water system may deteriorate as a result of the change in the ratio of storage to discharge capacity due to aging, urbanisation and climate change. We developed the...journal article 2023
