How does it work ?
To gain a better understanding of how a DMA and Smartrek work, let’s consider an example. When there is a small amount of water leakage within a large water supply system, it can be challenging to pinpoint the leak’s location precisely. However, if it appears in an area of typically low demand, the leak will likely be noticed, enabling corrective measures to be taken.
District-metered areas (DMAs) are widely used in some water systems to monitor any unusual demands commonly caused by leaks. A DMA works by isolating a certain portion of the system and taking note of all inflows, outflows, and variations in tank volumes.
In order to gain a deeper understanding of water loss and locate places to apply resources, it is essential to evaluate water flow through the system by installing flow meters and dividing the system into DMAs. By doing so, DMAs that appear to suffer from water loss can be more vigilantly monitored and incorporated into water loss reduction programs.
Smartrek’s role is to take real-time flow and pressure measurements at the DMAs at regular intervals. This data is then compared to water consumption data from an Advanced Metering Infrastructure (AMI) system and water flows from drinking water plants. If a plant detects a high-flow spike, Smartrek can determine which sector the flow is heading to and send a team to inspect for a possible water main break. Lastly, comparing data allows Smartrek to calculate the municipality’s total water losses accurately.
