Water Distribution

One critical issue for a water distribution network is water leakage from the piping. Yokogawa provides water loss management solutions based on the International Water Association (IWA) methodology to minimize losses from the network to reduce non-revenue water.

Overview of OpreX Water Loss Management System

Yokogawa provides a total water loss management system, OpreX Water Loss Management System, “OW-LS” (hereinafter abbreviated as OW-LS).
It’s a software product that detects water leakage occurrences at the District Metered Area (DMA) level, calculates the percentage of Non-Revenue Water (NRW), and provides optimized pressure management.
OW-LS measures the flow and pressure at the inlet of DMAs and send them through remote terminal units (RTU), to SCADA systems and OW-LS on the water distribution network.

Overview of water loss management

OW-LS consists of below three functions.

  • Water balance function
  • Night flow analysis function
  • Pressure management function

Features

  • Simple operation
    You can quickly access the required information using a simple operation via the browser and dashboard.
  • Integration with other systems
    You can manage various types of information by connecting to the billing system and CI server

Resources

Overview:
  • To bring the customer a real-time monitoring and management capability, Yokogawa installed STARDOM (FCJ), flow meters, and transmitters at key points throughout the distribution network.
  • The STARDOM FCJ controllers achieved an accurate water loss management system while keeping the running costs to a minimum.
Overview:

The Metropolitan Cebu Water District (MCWD) needed to improve its water supply system to keep up with the growing demand.
Yokogawa installed field instruments at a total of 143 locations in MCWD’s water distribution network and a SCADA system with water leakage management software at the main office to reduce non-revenue water and improve stability of water supply.

Overview:

Supervising and control water flow over the geographically distributed area is important to prevent fluid loss and disaster for fiscal and safety reasons.
