Impact of Pipe Cover on Drinking Water Temperature

Drinking water temperature is an essential parameter for water quality related to the physical, chemical and biological processes in water. However, in many countries, the drinking water temperature has not been taken seriously and was excluded from water quality standards. For example, in the Netherlands, the temperature of drinking water...

Quantification and modelling of organic micropollutant removal by reverse osmosis (RO) drinking water treatment

Reverse osmosis (RO) is the most promising membrane technology in organic micropollutants (MPs) removal of drinking water treatment. For 78 MPs, passage and removal were evaluated with an ESPA3 RO membrane and the robustness of RO against MPs was studied. The MPs were classified according to their charge and hydrophobicity. The results showed...

Drinking water temperature around the globe: Understanding, policies, challenges and opportunities

Water temperature is often monitored at water sources and treatment works; however, there is limited monitoring of the water temperature in the drinking water distribution system (DWDS), despite a known impact on physical, chemical and microbial reactions which impact water quality. A key parameter influencing drinking water temperature is...

Potential impact of a large-scale cascade reservoir on the spawning conditions of critical species in the Yangtze River, China

Dam building and reservoir operations alter the downstream hydrological regime, and as a result, affect the health of the river aquatic ecosystem, particularly for large-scale cascade reservoirs. This study investigated the impact of the Gezhouba Reservoir (GR) and the Three Gorges Reservoir (TGR) on the spawning conditions of two critical...

Nighttime cooling of an urban pond

One of the processes by which open water cools the air during hot summer days is by storing the heat and increasing its own temperature. This heat is then released at night. The aim of this paper is to analyze this cooling process by quantifying the magnitude of turbulent, latent and sensible, heat fluxes in comparison to radiative and ground...

Influence of an Extended Domestic Drinking Water System on the Drinking Water Quality

Drinking water and fire safety are strongly bonded to each other. Actual drinking water demand and fire flows are both delivered through the same network, and are both devoted to public health and safety. In The Netherlands, the discussion about fire flows supplied by the drinking water networks has drawn fire fighters and drinking water...

Assessing the Accuracy of Water Temperature Determination and Monitoring of Inland Surface Waters Using Landsat 7 ETM+ Thermal Infrared Images

This research evaluates the potential of thermal infrared (TIR) remote sensing to determine and continuously monitor the horizontal water temperature distribution of inland surface water bodies. Usually, monitoring temporal and spatial variability of surface water temperature takes place by measurement networks of in-situ gauges, but these...

High resolution temperature observations to identify different runoff processes

Headwater catchments are important contributors to streamflow. They are small, but all combined they influence river flow significantly. To be able to make proper runoff predictions under different climate conditions and changing land use, it is important to have detailed understanding of the discharge processes in the headwater catchments. In...

Klimaatbestendigheid van de drinkwatervoorziening in Nederland gebaseerd op oppervlaktewater

Deltares werkt momenteel in opdracht van RWS-Waterdienst aan de opzet van het project "Klimaatbestendigheid van Nederland Waterland". In dit project wordt onderzocht wat de klimaatbestendigheid is van het hoofdwatersysteem van Nederland. In het project staan twee vragen centraal: 1. Waar liggen de omslagpunten die leiden tot een ander...

De invloed van warmtelozingen op de watertemperatuur van de Rijn

Waterkwaliteit van de Rijn en de Maas bij (extreem) lage afvoeren

De zomer van 2003 werd gekenmerkt door aanhoudend hoge temperaturen en lage rivierafvoeren. De effecten van deze droogteperiode op de waterkwaliteit zijn tot op heden niet diepgaand onderzocht. De algemene indruk is dat de effecten wel mee zullen vallen. In de "Evaluatienota Waterbeheer Aanhoudende droogte 2003"(Min. V&W, 2004) wordt ook met...
