Methodology of functionality selection for water management software and examples of its application
When developing new software products and adapting existing software, project leaders have to decide which functionalities to keep, adapt or develop. They have to consider that the cost of making errors during the specification phase is extremely high. In this paper a formalised approach is proposed that considers the main criteria for selecting new software functions. The application of this ...

Salinity and miniDOT
The miniDOT and other optical dissolved oxygen sensors measure oxygen within a special plastic material that has the property of changing its fluorescence in response to the amount of oxygen present. Oxygen arrives within this material by diffusion from the surrounding environment, which is usually water. The miniDOT determines oxygen concentration in water dissolved oxygen by optically ...

The extension of EPANET source code to simulate unsteady flow in water distribution networks with variable head tanks
This paper describes the modifications applied to EPANET, a public-domain water distribution system modelling software package, that does not correctly compute the hydraulics of a water distribution network (WDN) with variable tank heads in (slow) unsteady flow conditions. Firstly the methodology adopted to extend the Global Gradient Algorithm (GGA) implemented in the original EPANET source ...

Experiences and lessons learned from practical implementation of a software-supported Water Safety Plan (WSP) approach
The Water Safety Plan (WSP) is considered the preferred approach to ensure drinking water safety by the World Health Organization (WHO). This approach ideally requires extensive scientific and technical input from a multidisciplinary team of experts. However, in small- and medium-sized municipalities in Austria, financial and personnel resources are usually of very limited availability. ...

Establishing the First Validated Dataset of North American Water Utility Water Audit Data
The American Water Works Association‟s (AWWA) Water Loss Control Committee (WLCC)assembled in 2011 an initial dataset of Water Audit data from 26 water systems from the United States and Canada. This effort represents the initial phase of a project that ultimately aims to establish North American water industry benchmarks for water loss control, while promoting the use of standardized water ...

Online Ground Water Monitoring for the Olympic Games 2008, China
Reference Project: Online Ground Water Monitoring for the Olympic Games 2008, China During the 2008 Olympics the rowing, canoeing and marathon swimming competitions took place at the Shunyi Water Park, which is situated in the northeast of Beijing. The artificial lakes within the Shunyi Water Park are partly supplied with ground water from surrounding wells. In cooperation with their Chinese ...

Drinking Water Resource Protection, Germany
Reference Project: Drinking Water Resource Protection, Germany In the catchment area of a major drinking water supplier in western Germany increasing nitrate concentrations were noticed within a deep water-bearing layer. Although high nitrate concentrations, resulting from regional intensive application of fertilizers, were known from shallow layers in the area, they were new to the deep ...

Water Technology: Five advantages of implementation
Water technology has gone from being an idea of the future to a real need. The current global water situation requires intelligent solutions which can tackle the challenges that lie ahead. Against this backdrop, the use of ad-hoc software multiplies the efficiency of water utilities. By water technology, we refer to innovative solutions designed to improve the management of all or part of the ...

Characterisation of water–oil drainage process through a reservoir rock sample by digital core analysis
Oil–water relative permeability and capillary pressure of a water–wet digital core are computed using the finite–volume/volume of fluid method and mimicking traditional laboratory steady–state experiments carried out on a water saturated sample. Commercial software is used for immiscible multiphase fluid flow simulations, carried out on a low–cost multicore workstation, and the pore–scale data ...

Integrating water distribution system efficiency into the water conservation strategy for California: a Los Angeles perspective
Improving water management in California requires a transition from imported to local water resources used efficiently. To assess this transitional capacity of water retailers in metropolitan Los Angeles County, we focused on a key water management metric: the water distribution efficiency. We traced the evolution of water loss reduction policy and practices globally with emphasis on ...

Spatiotemporal groundwater level forecasting and monitoring using a neural network–based approach in a semi arid zone
Forecasting the groundwater level (GWL) of an aquifer is one of the most important tasks in hydrogeology. Such forecasts prove vital to develop better exploitation strategies of water resources and to carry up–to–date groundwater monitoring. In this paper, an artificial neural network (ANN)–based approach, which was based on linear regression model, is presented to simulate and predict both ...

Valencia: sun, sea and Digital Twins
Defining a Digital Twin Valencia is perhaps better known for its arts, sciences, sandy beaches and futuristic structures rather than hosting one of the most advanced water software systems. Yet, underpinning the Spanish port city is a sophisticated ‘Digital Twin’ that demonstrated the model long before the term became fashionable. Before looking into the history and operation of ...

A practitioner’s perspective on the uses and future developments for wastewater treatment modelling
The modern age of wastewater treatment modelling began with publication of the International Water Association (IWA) Activated Sludge Model (ASM) No.1 and has advanced significantly since. Models are schematic representations of systems that are useful for analysis to support decision-making. The most appropriate model for a particular application often incorporates only those components ...

The importance of security in water infrastructures and the water sector
A thwarted attack against a water treatment plant in Florida in 2021, a failed attempt against pumping facilities in Israel in 2020, or a massive attack against the water supply of the Swiss city of Ebikon in 2018 through thousands of malware requests increased concerns within the water sector. While water infrastructures are not attacked as much as other utilities, they are vulnerable due to ...
