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...

Het meten van hydraulisch functioneren van rioolstelsels is inmiddels gemeengoed in Nederland. Desondanks zijn de ervaringen niet onverdeeld positief en laat de dataopbrengst nogal eens te wensen over. Bij Waterschap De Dommel is in het kader van het Kallisto-project een omvangrijk meetnet met onder meer meetopstellingen bij ruim 200 overstorten...

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...

In het project Kallisto werken gemeenten, waterschappen en universiteiten samen aan innovatieve oplossingen voor de afvalwaterketen in de omgeving van Eindhoven. Dat doen ze onder het motto "samen, slim, schoon". Om de waterkwaliteit van de rivier de Dommel te verbeteren richt Kallisto zich op sturing in de afvalwaterketen. De ecologische...

Shale gas is natural gas captured in low permeable shale formations, to be able to produce this gas the permeability of the reservoir needs to be enhanced. Hydraulic fracturing is used in low permeable reservoirs to increase the permeability and make gas production possible. Fracking fluid is pumped in the reservoir at high pressure to create...

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...

Asset management is a prerequisite for maintaining the required level of serviceability of urban drainage systems. The required asset management effort to achieve a certain level of service is unclear due to sewer systems process and structure complexity. One of the main questions of asset management is what kind of information is needed, and...
