Description of the case study

Aiming to meet the challenges of the project and deliver smarter, innovative analytics, AGS and LNEC, alongside with the water utility Águas de Barcelos, lead the design and implementation of a pilot case study in the City of Barcelos (Northern Portugal).

The case study consists of three District Metered Areas within the city area. Network flow and pressure data are available from a SCADA system for these areas, alongside PoU telemetry systems collecting real-time water consumption data for ca. 300 households.

Case study profile:

  • Buildings & dwellings: Apartment blocks –DMA1, semi-detached and detached houses - DMA2, detached - DMA3
  • 390 water meters connected to telemetry system (oscillating piston type, nominal diameter 15-80 mm)
  • 5 flow meters connected to SCADA system (electromagnetic type, nominal diameter 50 mm)
  • Transmission type - radio, GSM/GPRS
  • Time interval between records for water meters – 1 hour with a minimum time interval of 15 minutes in specific scenarios

Overview of Portuguese case Study: a) DMA1, b) DMA 2, c) DMA 3

Specific objectives of the case study

  • Assess the contribution of telemetry systems to successful water loss control at network level (pressure management, leak detection, unauthorized consumption identification, detection of meter underegistration) and quantify the benefits in terms of billed consumption, energy saving, leaks reduction and capital investment.
  • Profiling and detection of network-level and household-level leakage events or deviations from an efficient behaviour - including defining efficient profiles, and helping the consumer to identify inefficient water usage.
  • Assess the effective benefits of changes in consumption habits in terms of water/energy management for network operation (pumping or storage deferment, viability of peak flow control).
  • Identify users or categories of users with a large potential for efficient water use (e.g., sprinkler systems), recommend specific practices to promote it, estimate the impacts of this practices in terms of billed consumption and efficient use.
  • Utilization of telemetry systems to promote new services to users (leakage alerts, promote efficient use practices, comparative consumption analysis).
