Our recommended approach to water loss management commences with the compilation of a Water Loss Management Plan. This identifies the most cost effective and sustainable methods relevant to the specific needs of the client's water network, and provides the budgetary information necessary to implement such a plan.
The scope of the Water Loss Management Plan includes the following areas:
- Real losses - water lost from reticulation network through bursts and leaks including losses from reservoirs. Apparent loss - lost revenue through inaccurate residential metering, unmetered supplies and theft; this also leads to inaccurate calculation of annual water balance.
- Sectorisation - splitting of network into separate district metered areas (DMA's) to assist in ongoing monitoring of water loss and system performance.
- Minimum night flow monitoring - operational method of measuring water loss on a daily basis allowing for rapid response to leaks and busts, leading to substantial water savings.
- Annual water balance - calculation of net water loss using analysis of all water inputs and outputs. This is usually used for reporting purposes and should be used in conjunction with the minimum night flow analysis.
- Pressure management - control of pressure in water reticulation systems to increase asset life and reduce leakage from small leaks and weeping joints that cannot be found through available leak detection techniques.
- Active leakage management - find and fix leakage in water reticulation systems using survey techniques.
- GIS update - update of geographical information systems with correct pipe network information after thorough on-site investigation.
- Networking modeling - desktop-based study of water flows and pressures in a reticulation system to assist in planning and investigation for future system requirements.
The Water Loss Management Plan provides a major component of each water utility's Integrated Water Cycle Management Plan; it's implementation not only provides significant water savings but allows accurate provision of data for government reporting such as the Australian and State Government reporting requirements.
In addition to a Water Loss Management Plan, WaterGroup is able to provide hands-on technical assistance such as installation of flow monitoring and pressure monitoring equipment, commissioning of pressure and flow management assets, staff training and site investigation work.
Through Water Loss Management Planning and subsequent on-site work WaterGroup intends to leave a legacy of measurable and sustainable water loss systems for Australian water utilities.
