Drill core samples are taken in practice for an analysis of the material characteristics of concrete pipes in order to improve the quality of the decision-making on rehabilitation actions. Earlier research has demonstrated that core sampling is associated with a significant uncertainty. In this paper, the results of core samples are compared...

Gully pots are essential assets designed to relief the downstream system by trapping solids and attached pollutants suspended in runoff. This study applied a methodology to develop a quantitative gully pot sedimentation and blockage model. To this end, sediment bed level time series from 300 gully pots, spanning 15 months, were collected. A...

Decision-making for sewer asset management is partially based on intuition and often lacks explicit argumentation, hampering decision transparency and reproducibility. It is unknown to what extent each information source is appreciated by decision makers. Further insight into this relative importance and into implicit factors, improves...

Modelling of the integrated urban water system is a powerful tool to optimise wastewater system performance or to find cost-effective solutions for receiving water problems. One of the challenges of integrated modelling is the prediction of water quality at the inlet of a WWTP. Recent applications of water quality sensors have resulted in the...

There is still a long way to go in understanding the behaviour of solids in sewers due to the difficulties in obtaining sufficient monitoring data to be able to understand the dominant processes. Laser profilers have shown to be capable of measuring the pipe interior, with a high accuracy, which is sufficient to be able to detect and quantify...

It remains unknown how lateral house connections affect the performance of the sewer system, since the assessment of serviceability is mainly based on the state of the main sewer system. Further insight into the contribution of lateral house connections to the overall level of service provided can aid to target investments to parts of the system...

Being able to accurately determine weir discharges is of key importance in urban water management. The most common method is performing a level measurement and calculating the discharge using the standard weir equation. Since this equation is only valid in certain conditions, this can lead to large deviations from the actual discharge. In this...

The principle of structural behaviour of buried concrete pipes is fairly understood, except for how material deterioration affects structural behaviour and performance. Consequently, information on the structural behaviour of deteriorated sewer pipes will contribute to better understanding of the changes in status, which is essential for...

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...

The objective of this paper is to demonstrate the applicability of, and need for, surrogate sensors as robust sensors for water quality based RTC. For this purpose 1.5 years of level, conductivity (EC) and turbidity (TU) measurements at 9 combined sewer overflow (CSO) locations have been performed and analysed to determine the most polluted CSO...

Passend rioleringsbeheer is nodig om voldoende dienstlevering te balanceren met investeringskosten. Besluitvorming binnen rioleringsbeheer kan echter bemoeilijkt worden door gebrek aan data en interacties met verschillende actoren. Deze beperkingen zorgen veelal voor niet heldere en niet reproduceerbare besluitvormingsprocessen, die voornamelijk...

Previous research learned that the reproducibility of visual sewer inspection data is poor (Dirksen et al.). Further research by Arjan et al. showed that the applied coding system has a major influence on the reproducibility. The aim of this study was to give relevant suggestions to improve the quality by defining defects that are in the current...

Since the initiation of environmental legislation, monitoring campaigns have been done to estimate the characteristic pollutant concentrations of combined sewer overflow water. Such local campaigns are expensive due to the large number of events which should ideally be followed. This study focused on whether available concentration ranges from...

In 2010 is binnen liet KRW-innovatieproject KALLISTO onderzocht hoe op een effectieve manier de waterkwaliteit in de Dommel verbeterd kan worden, zodat een goede ecologische toestand wordt gerealiseerd. Daarvoor is een nieuw toetsingskader voor chemische en ecologische waterkwaliteit ontwikkeld. Dit toetsingskader is opgesteld om specifiek het...

De waterkwaliteit in de rivier de Dommel is onvoldoende voor het bereiken van een goede ecologische toestand. In de toekomst zijn daarom aanvullende maatregelen vereist. Onder het motto ´Samen, Slim, Schoon´ is Waterschap De Dommel met de gemeente Eindhoven en negen andere gemeenten in het stroomgebied van de Dommel daarom het project Kallisto...

Sewer systems are capital-intensive infrastructures, requiring appropriate asset management to safeguard serviceability. In the Netherlands, effective sewer asset management is described by De Leeuw’s control paradigm. Reliable data and information are key elements in decision-making for rehabilitation and renewal of the assets. Rehabilitation...
