A real-time web application
which efficiently identifies and targets leaks
in water distribution networks.
Sim-On™ Water combines multiple data sources and uses the latest mathematical approaches to identify leaks, so that they can be repaired rapidly, saving water.
Sim-On™ Water has been designed to cut down time, effort and uncertainty in identifying smaller leaks on water distribution networks. Separate algorithms have a focus on District Metered Areas (DMAs) and Trunk Mains. A dashboard, which is accessed via a web browser on desktops or mobiles, makes it easy for managers to see areas where leakage is high, providing valuable information for deploying field resources. It improves teams’ response time to finding and therefore repairing leaks, cutting costs and saving time and money for water companies.
Using Sim-On™ Water, operational teams can easily
- Collect, clean and analyse flow-pressure data from SCADA and loggers
- Quickly identify new leaks in the system
- Assess overall DMA performance and so allocate better search and repair efforts
- Assess water trunk main performance and determine the level of leakage in each system
- Reduce the search area for leakage via the leakage locating module
- Operate the network better via a decision support tool that helps to assess and visualise consequences of planned or emergency operations.
Key features
- Connect to a large range of data systems and loggers
Sim-On™ Water can connect directly to a large range of SCADA systems and logger data, collecting, combining and integrating data arriving from different sources. - Prompt and timely results for operational use
Sim-On™ Water runs data collection and sophisticated calculations overnight. Results are available promptly each day improving teams’ response time to finding and therefore repairing leaks. - A flexible, web-based solution
It works on any device or location. There is no need to install or manage desktop applications, making it particularly easy for IT teams to manage, and for updates to be delivered. - A user-friendly and intuitive interface
Operators will find it quick and easy to access and interrogate the system with very limited training.
Three integrated modules
Module 1: DMA flow data analysis
This module reads and analyses flow sensor data via a flexible connector that can capture and consolidate data from a large range of sources.
Sim-On™ Water uses sophisticated statistical algorithms to judge in an automated way if the flow balance has deviated from its standard trend. It can then assess how leakages have developed over time in each DMA or each Trunk Main. The results of the analyses are available promptly each day as data collection and calculations are made overnight. The leakage manager can then allocate rapidly and appropriately field resources to prioritize and tackle the most urgent tasks.
A dashboard, which is accessed via a web browser on desktops or mobiles, makes it easy for managers to see areas where leakage is high, providing valuable information for deploying field resources. It improves teams’ response time to finding and therefore repairing leaks, cutting costs and saving time and money for water companies.
Informative maps and timeseries graphs are available; these can refer to previous days of the year, enabling the user to quickly and easily view performance across the catchment over time.
Module 2: Leakage locating
This module builds upon Module 1 results. It launches a geographical search for the leakage, aiming to ascertain the most likely location. This second module requires additional data from such sources as a water model data file and real-time pressure sensors.
Module 3: Real-time what-if scenarios
This module provides a real-time what-if scenario tool that operators can use to assess the consequences of field operations such as valve closure, hydrant opening, pipe repairs, pump maintenance and so on.
This third module performs simulations via a connection to InfoWorks WS Pro (well-known modelling software).
Sim-On™ Water’s user-friendly and intuitive interface
Estimated leak trend over an extended period of time with confidence boundaries. 
A colour coded map, which shows the level of criticality of each DMA on a familiar green – yellow – red scale. 
Each DMA is connected real time to the flow measurements and the flow balance is calculated every 15 minutes. 
Each DMA is defined by a number of parameters, needed to estimate the level of leak and to calculate other strategic indicators such as leakage per km or dynamic ILI.
