Capability Statement & Policy

Water Loss Management Business Cases

The Water Loss and Pressure Management Team is able to use the latest software developed by Water Services Association of Australia (WSAA) using the techniques recommended by the IWA Water Loss Task Force to assist water authorities to identify an appropriate water loss management strategy for your town or city.

This approach will assist clients to develop and justify appropriate capital investment programs to fund the implementation of water loss and pressure management projects based on sound business investment approaches.

Using best practice software applications the WLPM team is able to accurately model:

• Economic and financial savings from the implementation of best practice water loss programs.
• Burst frequency savings from the implementation of pressure management.
• Water loss savings both in network and post meter.
• The economic level of leakage for your network and circumstances.

The team is also able to use these tools to undertake post program implementation reviews which will enable clients to accurately measure program benefits and ensure long term sustainability of water savings.



District Meter Area/Pressure Managed Zones

Water Loss and Pressure Management (WLPM) team has extensive experience in water demand management, including:

     DMA Establishment & Optimisation

• Divide, plan/model, optimize and design network sectors for future District Meter Areas (DMA) or Pressure Management Zones (PMZ).
• Flow meter specification and engineering design
• Identification and engineering design of any needed augmentation.
• Identification of data logging monitoring points (average zone point, inlet and critical points).
• Site work including:
  - Boundary valve integrity testing
  - Flow and pressure logging
  - Zero pressure test
  - Fire flow testing

• Implementation of pressure management schemes including:
  - PRV sizing & specification
  - Identification of areas suitable for pressure management
  - Communication Management

     DMA Management

• Daily monitoring and reporting of flow and pressure data
• Reporting on physical losses on DMA, water supply zone and utility levels
• Assessment of Minimum Night Flows to determine potentially recoverable excess losses and target setting for individual DMA’s
• Informing utilities of data continuity issues, such as flat logger batteries and communication problems
• Calculation of Top Down and Bottom Up Water Balance
• Calculation of Infrastructure Leakage Index (ILI)
• Economic Level of Leakage (ELL) definition and evaluation
• Operational Manual and Handover reports

Leak Detection Survey

WLPM team has international and national experience of more than 20 years in leak detection surveys with projects conducted in UK, Malaysia and Australia-wide. Its accuracy and report quality are well known in the water industry.

The team is fully equipped with the latest leak detection equipment (listening stick, correlator, ground microphone etc) available 24/7 to conduct routine or emergency surveys.

Water Network Modelling

WLPM’s senior modelling engineer has more than 10 years of experience with international and national projects, including:



• Pressure and leakage management zone planning and design, including business case and cost benefit analysis
• Bulk water and reticulation network planning and design, including Priority Infrastructure Plans
• Network analysis and optimisation
• Development application water (and sewerage) network capacity assessment
• Network model development, creation, updating & calibration
• GIS data development, creation and mapping
• Development of water consumption demand/profiles and service supply standards
• Preliminary design and costing of network augmentations and upgrades

Bulk Meter Audit

WLPM’s engineers performed several bulk meter audits for bulk water supply companies and utilities as well. These audits included:



• Bulk flow meter installation, using a standardised questionnaire developed by WLPM
• Bulk flow meter size analysis
• For installations where significant flow rate variations occurred, the meter flow history and the flow meter envelope were analysed
• Flow interruption analysis
• Bulk flow meter records review to assess compliance with manufacturer’s guidelines
• Flow meter compliance with national regulations
• Bulk flow meter renewal priority plan and project management

Revenue water meter audit

WLPM’s members have performed revenue water meter audits in Australia and Indonesia, with excellent results in terms of apparent losses reduction and billed consumption increase. The audit consists of:



• Domestic and commercial revenue water meter installation and renewal procedures study
• Installation of flow loggers at the commercial meters to assess against the meter reading and the meter envelope
• Standard meter’s flow analysis by location (possibility of different water quality) and customer type
• Water meter test bench analysis and results compared with existing renewal policies
• Meter renewal priority plan and project management

Communication Management

Management of the communication process is an essential function in any project. Effective identification and engagement of stakeholders combined with the design and execution of communication procedures are critical in ensuring project success.

WLPM has extensive experience in the development, approval and implementation of Communication Management Plans for Demand Management Projects.

SCADA/Telemetry

WLPM has considerable experience in integrating pressure and leakage management infrastructure with their client's SCADA and telemetry systems. In recent projects WLPM have project managed the design, tendering, construction and commissioning of 80 radio telemetry sites for Logan Water and 63 mobile data network telemetry sites for Gold Coast Water.

A typical DMA/PMZ installation includes a Kingfisher telemetry RTU that communicates via radio or 3G/4G to a ClearSCADA control room application. The telemetry system and SCADA interface provide the operator with real time alarm events and data on network performance. The flow modulated pressure management control logic is programmed into the local RTU however the operator can remotely change settings or override the operation of the PRV control valve.

WLPM will manage the design and specification of a reliable and cost effective telemetry system to support the implementation of flow modulated pressure management systems. This will ensure that accurate and complete system performance information is available for current operations and future planning requirements.

DMA/PMZ Data Management

WLPM has access to a DMA data management & analysis database (developed by Water Systems Optimisation, a UK based company) which is ideally suited to any utility operating DMA’s. It is a web based system (so anyone with an internet connection can view it) which imports flow and pressure data from DMA’s and can then be used as a data viewer, alarm system (for missing data and for exceptions outside of the expected 24 hour flow & pressure profile) and report generator. It allows utilities to convert the raw DMA data into information upon which strategic operational decisions can be based. It can be configured to provide a daily calculation of whether their DMA’s have reached an economic level of intervention which would then require Active Leakage Control.

training

WLPM’s team has had extensive experience in training and capacity building in all areas of water loss and asset management. This unique blend of international operational experience, strong technical knowledge and IWA Water Loss Task Force update makes WLPM the natural choice for training local and international delegates.
