Description
This unit describes the skills and knowledge required to conduct a water use audit for a ‘process’. In this unit a process could be an organisation, a significant part of an organisation or part of the value chain. This unit applies to managers, operational or technical experts or others who are required to quantify water use from all sources, compare actual with theoretical (optimal) usage and recommend improvement strategies. This unit applies to any organisation. No licensing or certification requirements exist at the time of publication. Relevant legislation, industry standards and codes of practice within Australia must be applied.
Notes
Elements and Performance Criteria
1. Identify all sources and uses of water in process
  • 1.1 Define the scope and parameters of process to be audited according to regulatory and/or organisational requirements
  • 1.2 Identify all external and internal sources of water relevant to process and categorise by quality
  • 1.3 Identify all uses of water by process steps and related plant and equipment and quality of water used
2. Calculate theoretical use of water
  • 2.1 Calculate theoretical net use of water for each process step
  • 2.2 Calculate overall water balance for process
  • 2.3 Evaluate the need for water consumption and water quality by process compared to alternative processes
3. Measure actual use of water
  • 3.1 Calculate actual net water use for overall process
  • 3.2 Calculate actual net water use for each process step
  • 3.3 Calculate difference between theoretical and actual water use by process step and overall
  • 3.4 Determine current and optimal water quality for each process step
4. Develop strategies for improving water usage
  • 4.1 Rank process steps by difference between theoretical and actual water use
  • 4.2 Rank process steps by actual water use
  • 4.3 Identify process steps using higher quality water than required
  • 4.4 Prioritise process steps with potential for significant water usage improvements
  • 4.5 Develop strategies for improvements in priority process steps
  • 4.6 Determine expected improvement in theoretical water consumption and/or water quality usage for each strategy
5. Recommend water usage improvements
  • 5.1 Consult with key stakeholders to confirm or amend strategies
  • 5.2 Identify strategies related to regulatory and/or organisational requirements
  • 5.3 Rank strategies by cost-benefit ratio
  • 5.4 Short-list preferred water usage improvement strategies
  • 5.5 Write report to present audit outcomes and recommendations for improving water usage
