The main goal of the Non-Revenue Water Management system is to monitor and manage of water distribution system.
System is used to detect and calculate non-revenue water basing on following cascade approach:
- Real time detection
- Area balancing
- Field inspections.
Real time detection is based on signals received from sensors installed at crucial distribution network elements. Sensors measure and send information about flows and/or pressure. Data is received by IT solution, analysed and visualized for network operators who undertake remedial actions in a case of leakage detection. To manage this process of real time detection the SCADA class system is provided. Number and location of sensors are proposed by SCADA system vendor.
is done by calculate of area balances of water input, output water volume and area consumption. Balance structure can be changed in a case when new metering point is established, or existing metering point is removed from operation. Balance structure is multilevel which support top down analysis to provided different point of view. Time horizon and balancing frequency are adjusted to reading schedule of metering points from balanced area.
In a case when calculated imbalance water volume is exceeding control thresholds then system should trigger warning message and allow to start investigation tasks for field inspection.
This step of leakage detection is supported by dedicated software components which allow to gather readings from SCADA solution and support metering data acquisition from end customer metering devices.
