Besseling, Roos (author), van Marrewijk, Josine (author), Slokker, Marloes (author), van der Zwet, Ilse (author)In many places in Uganda, people do not have a connection to the drinking water supply system and there is a lack of treated water supply, meaning that people only have access to water a certain part of the day. As a result many people rely on springs, handpumps, rivers or lakes, of which the quality cannot be monitored or controlled. <br/><br/...student report 2023

Houben, Georg J. (author), Collins, Sarah (author), Bakker, M. (author), Daffner, Thomas (author), Triller, Falk (author), Kacimov, Anvar (author)Horizontal wells play an often overlooked role in hydrogeology and aquifer remediation but can be an interesting option for many applications. This study reviews the constructional and hydraulic aspects that distinguish them from vertical wells. Flow patterns towards them are much more complicated than those for vertical wells, which makes their...journal article 2022

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

Sarisen, Dondu (author), Koukoravas, Vasilis (author), Farmani, Raziyeh (author), Kapelan, Z. (author), Memon, Fayyaz Ali (author)Intermittent water supply (IWS) is widely used around the world, and with the increase in population and predicted future water scarcity, IWS applications seem to continue. While most of the existing studies on water supply concentrate on continuous water supply (CWS), the research focused on the IWS is now becoming mainstream. Hydraulic...review 2022

Ophof, Oscar (author)The historic inner-cities in The Netherlands are largely known for their iconic channels and their accompanying quay walls, of which a significant number were constructed over 100 years ago. Due to the limited available space in the sub-surface of the urban environment, a high number of utility lines (i.e. potable water pipes and sewer systems)...master thesis 2021

Verboeket, Rik (author)The Volkerak-Zoommeer is a former estuary located the Rhine Meuse Delta in the southwestern part of the Netherlands. After the completion of the Volkerakdam, Philipsdam and Oesterdam as part of the Delta Works, this estuary was cut of from the Oosterschelde and a fresh water lake was formed in a sea water environment. This new lake became the...master thesis 2021

Nguyen, T (author)This MSc thesis is a contribution to the African Water Corridor (AWC) project that gains insight into the future of water supply systems in the Sub-Saharan African small towns. The future water demand in these areas constitute a great challenge in the effort to provide safe water for everyone. Unfortunately, there are high uncertainties in the...master thesis 2021

Verbart, Joost (author)This thesis proposes a novel design approach for a monitoring system that can detect hidden leaks in intermittent water supply (IWS) systems. Cities with IWS conditions in their drinking water network, such as Nairobi and Harare, often have a high percentage of non-revenue water (NRW) in their system. Estimations of the amount of NRW in these...master thesis 2021

Versteeg, Niki (author), Hermans, L.M. (author), Ahrari, Sara (author), van de Walle, B.A. (author)Most water and development interventions aim to contribute to long-term sustainable impacts. Given the uncertainties involved in these longer-term water development projects, adaptive planning approaches hold promise to connect planning, implementation and evaluation. Recent innovations report promising results, but find limited wide-spread...journal article 2021

Loen, S.S. (author)Securing fresh water supply on the Dutch Caribbean islands, former colonial overseas territories of The Netherlands from the 17th century, always has been, and still is, a challenge. Between 1904 and 1915 the cartographers Werbata and Jonckheer drew the first topographical maps of the islands. Detailed data was needed for the (re-)development of...conference paper 2021

(author)Background: There is increasing recognition of the complexity underlying WASH conditions in developing countries. This article explores the complexity by assessing the vulnerability of a specific area to poor WASH conditions using a qualitative approach. Methods: We present our findings for the district of East Sumba in Indonesia. This area...journal article 2021

Daniel, D. (author), Prawira, Julivius (author), Djono, Trimo Pamudji Al (author), Subandriyo, S. (author), Rezagama, Arya (author), Purwanto, Aries (author)The sustainability of the water supply program in developing countries is influenced by many inter-linked and dynamic factors, suggesting the need to analyse the system behaviour of the water supply program. However, no study analyses factors influencing the sustainability of rural drinking water supply programs holistically, and this study...journal article 2021

Al-Washali, T.M.Y. (author)Water utilities worldwide lose 128 billion cubic meters annually, causing annual monetary losses estimated at USD 40 billion. Most of these losses occur in developing countries (74%). This calls for a rethinking of the challenges facing water utilities in developing countries, foremost of which is the assessment of water losses in intermittent...doctoral thesis 2020

Guo, Cheng (author)In Bangladeshi rural areas, the groundwater may get contaminated with chemical contaminants. Aiming at removing chemical contaminants, piped water supply(PWS) systems were built. However, due to insufficient water quality tests, a lack of households' participation with the monitoring and maintenance of the PWS system, together with a lack of an...master thesis 2020

THOMAS, NAYANTARA (author)When we think about the fact that 70% of the earth is covered by water, it may be easy to assume that water is abundant and that it would never have to be an issue in terms of having a constant supply to drink. In reality, it is a very complex matter for everyone to be able to access and drink safe water. Water is essential to maintain life on...master thesis 2020

Keshav, S. (author)Big data sources can play an important role in revolutionizing the field of water resources research. Time series data with high temporal and spatial dimensions encapsulates with itself numerous factors essential for coming up with robust decisions. In this thesis, we assess one such big data source for efficient water management in the Oum Er...master thesis 2020

Huang, Hongjie (author)Water is one of the long-standing problems in Sint Maarten. Water supply is scarce while water demand is high. Water pollution and incomplete infrastructure also needs to be tackled. How can a cluster scale decentralized water management system solve water challenges in the hurricane-prone environment of Sint Maarten is the research question....master thesis 2020

den Dekker, Pieter (author)In this thesis, I develop and evaluate a demand-side approach to transition from an intermittent to a continuous water supply using a district metered areas approach in Accra, Ghana, an urban metroplex of 4.0 million persons in western Africa. Intermittent water supply (IWS) is inherently inefficient. These systems foment health hazards and are...master thesis 2020

Sakomoto, Takuya (author), Lutaaya, Mahmood (author), Abraham, E. (author)Intermittent water supply networks risk microbial and chemical contamination through multiple mechanisms. In particular, in the cities of developing countries, where intrusion through leaky pipes are more prevalent and the sanitation systems coverage is low, contaminated water can be a public health hazard. Although countries using intermittent...journal article 2020

Loen, S.S. (author)Cities worldwide currently face freshwater shortages. Forecasts predict that demand will outstrip naturally renewable and available water supplies by 40% by 2030. This poses a serious threat to livability in cities and urban areas that are already struggling with water-related issues like floods and land subsidence. Water insecurity, in...book chapter 2020
