WONE®

water optimization for network efficiency

A GLOBAL SOLUTION TO A GLOBAL WATER CHALENGE

The WONE® system is based on the implementation of district metered areas (dmas) and analysis of their flow and pressure data, which allow the user to combine processes and integrate relevant information for network management and control water losses.

The implementation of WONE®, within an active leakage control strategy, has reduced levels of Non-Revenue Water (NRW) in Lisbon Distribution Network from 23.5% in 2005 to 8% in 2015, positioning EPAL amongst an elite worldwide group of the most efficient water utilities.

Potential Users?

Water Management Utilities
WONE® is devoted to a strategy focused on efficiency, reducing losses and optimization of the supply system, with important results in economic, social and environmental terms.

WONE® Methodology

WONE® is supported by a software application that automatically undertakes the integration of DMA monitoring data. The WONE® application includes DMA performance indicators, ranking them based on total daily consumption, minimum nightline values, estimated recoverable water losses and enables trend analysis along with generating intervention alerts.

The system includes the following phases:
1. Network Analysis and sectorization planning
  • Field Validation and analysis of alternative DMA boundaries
  • Confirmation of operability and integrity of the zones
  • Analysis of GIS information
2. Sectorization and continuous monitoring of the supply network
  • DMA Planning and implementation | Including creation of measurement and telemetry points, validation of the design and boundaries as well as tests for DMA implementation
  • Continuous monitoring | Including flow and pressure control systems with passive telemetry registering data every 15 minutes and daily communications along with active alarms pressure
3. Integrated Analysis of permanent and systematic data from different systems
  • Customer Telemetry System, AQUAmatrix®, SCADA, GIS, G/Interaqua GIS, Automatic Meter Reading (AMR)
4. Planning of field interventions and quantification of recoverable water volumes
5. Interaction with leak repair teams

Differentiating Factors

  • User-friendly interface via Internet with cloud technology
  • Allowing multiple users simultaneously
  • Responds to the needs of different areas of the utility
  • Statistic & KPI calculation, attractive graphical presentation
  • Integration of alarms and alerts
  • Easy adaptation and development

Results

  • Proactive leak detection and water loss reduction
  • Improved planning of repair interventions and cost reduction
  • More efficient use of scarce water resources
  • Decreased “ecological footprint” and reductions in energy consumption, reagents use and CO2 emissions

WONE®

Proven to be successful, adaptable and universally applicable.
Can support any utility manager to reduce water losses and increase efficiency.
Developed and tested by EPAL, the oldest and largest water utility in Portugal.
