Drinking water companies in the Netherlands do special projects worldwide to improve the quality of installations but also support the local engineering. In Kabatini, Kenya, a well field with eight boreholes, nearly all with high maintenance cost, needed to be analyzed for replacement with high efficiency pumps. This project was important for both the village and the investors to create a base ...

Manager, Hydrogeology, 5 Shoreham Drive, Downsview, ON M3N1S4 Tel:416-661-6600×5369 [email protected] Key Personnel: Dirk Kassenaar and E.J. Wexler Working for the Toronto and Region Conservation Authority (TRCA), Earthfx provided key surface water and groundwater analysis components of the Humber River Watershed Plan. The ...
Project Summary Project DTK Hydronet Solutions, an advanced water distribution and storm and sewer network modeling company, was retained by the Public Health and Environmental Engineering Department (PHED) of West Bengal and the Asian Development Bank to provide water distribution services to Bankura. ...
In this study, the potential economic and hydraulic benefits of utilizing variable speed pumps (VSPs) in water supply systems are reported. A simple water distribution network simulation is carried out by EPANET and Bentley HAMMER models to examine variable speed operation. It was found that using VSPs could control and ...
The increasing use of plastic materials has modified several aspects of design and management of water distribution systems. With reference to the numerical modeling of transients, the definition of a correct rheological model of the pipe material is receiving an increasing interest. In this paper the behavior of the ...
Nutrient fluxes in stream basins need to be controlled to achieve good water quality status. In stream basins with intensive agricultural activities, nutrients predominantly come from diffuse sources. ...
This paper examines the hydraulic behavior of leakage from water distribution systems under condition of cavitation. For this purpose, an experimental model featuring small (i.e., a fraction of a millimeter) orifice openings was designed and built to simulate idealized cracks in defective pipes. During the tests, water was ...
The effects of different dosages of sodium hexametaphosphate and sodium orthophosphate on corrosion inhibition and water quality in two model water distribution systems, and the corrosion inhibition mechanism on pipe walls were investigated. Results show that adding sodium hexametaphosphate and sodium orthophosphate can not ...
Event-based rainfall–runoff models are useful tools for hydrologic design. Of the many loss models, the ‘initial loss-continuing loss’ model is widely adopted in practice. ...
In water distribution network calibration of quality models, bulk and wall decay coefficients are considered to be the adjustable parameters. ...
External water intrusion during low or negative pressure transient events in urban water supply systems may cause pollution and health problems. ...
Modern distributed water-aware technologies (including, for example, greywater recycling and rainwater harvesting) enable water reuse at the scale of household or neighbourhood. ...
The household biosand filter (BSF) is a highly utilized point-of-use water treatment tool. The effect of ambient temperature on the ability of the BSF to remove microbes from water is unclear. Model filters were distributed among different temperature-controlled laboratories and dosed daily with surface water ...
Sustainable management of water distribution networks (WDNs) requires effective exploitation of available data from pressure/flow devices. ...
The blind source separation theory was introduced and the trend and amplitude (TAA) model was established in order to overcome the shortcomings of some traditional global leakage discharge analysis models in water distribution systems (WDS). The TAA model considers the leakage discharge as one part of the ...
The hydraulic analysis of water distribution networks (WDNs) is divided into two approaches: namely, a demand-driven analysis (DDA) and a pressure-driven analysis (PDA). ...
Water demand is the driving force behind hydraulic dynamics in water distribution systems. ...
Chlorine-based disinfection agents are known to favor the production of disinfection by-products (DBPs), whose concentrations are restricted by international guidelines to ensure a safe consumption of drinking water. Hence, it is important to understand the behavior of DBPs within water distribution networks (WDNs) to avoid users' exposure to ...
Subsequent to the least cost design problem of water distribution systems (WDSs), optimal operation is probably the most explored topic. ...
