Abstract In this paper information from Water Authorities in the USA, Europe, Middle East and Australia that have purchased permanent monitoring leak detection equipment is reviewed and the findings are presented in a structured format that covers the following: Justification for permanent monitoring Evaluating the different product offerings Selecting the deployment zone Installation challenges Collection and validation of the data Handling false Alarms Managing the change in operational procedures Calc...
Unique Danish partnership against global water losses - Leakman, Denmark - Case Study
Nine Danish partners have formed a consortium with the objective to demonstrate the use and effect of integrated high-end solutions within Leakage Management based on Danish technologies and know-how. The nine partners represent leading technology providers, consultants, water utilities and the Technical University of Denmark. The project – named the LEAKman project – is initiated to demonstrate Danish solutions for reducing urban water loss and pave the way for new technological developments. It...
Hydraulic simulation of perforated pipe systems feeding vertical flow constructed wetlands
For successfully operating a vertical flow constructed wetland, the uniform distribution of wastewater on the surface of the soil filter is essential. In research, however, this aspect is often overlooked. This study presents a methodology for assessing discharge uniformity from perforated pipe systems via hydraulic modeling. First, the requirements and conditions for the simulation of perforated pipe systems are investigated and the model basics are explained. Then the whole process of model build-up, calibration,...
An assessment of sub-standard water pressure in South African potable distribution systems
Sub-standard residual water pressures in urban water distribution systems (WDS) are a prevalent phenomenon in developing countries – South Africa being no exception. The phenomenon of sub-standard pressure is poorly understood, with intermittent supply ultimately resulting when there is no residual pressure left in the system. This research addressed the prevalence and extent of sub-standard pressures by using hydraulic models of potable WDS for 71 South African towns, located in 17 different South African...
HydroMP – a computing platform for hydrodynamic simulation based on cloud computing
Modern water management decisions are increasingly dependent on efficient numerical simulations of multiple scenarios with multi-models. In this paper, a service mode for the hydrodynamic simulation based on cloud computing is proposed, and the relevant frameworks of the Hydrologic/Hydraulic Modeling Platform (HydroMP) are designed and implemented. Various hydro-models can be integrated into HydroMP dynamically without the need of program recompiling, since it achieves the scheduling of computing resources to...
