16 Auditing Foundations 16

17 Basic Concepts 1. Utilize the Balance. 2. Separate Total Loss into Real and Apparent Loss. 3. Separate Real and Apparent Loss into their subcomponents. 4. Use metrics in units of Volume, Value & Validity. 17

20 Non-Revenue 1. put into the system that does NOT return revenue to the Utility. 2. All Loss plus Unbilled Consumption. 3. Unaccounted-for water has been abandoned as an obsolete practice (2003). 20

23 Fire Dept Usage Operational Flushing Tools for control include efficient flushing practices and awareness campaigns Unbilled Authorized Consumption Non-physical / revenue loss - slow meters, billing issues and theft Cost impacts at retail rate. Tools for control include data management, quality control policies/practices, & meter testing & repair Apparent Losses Non- Revenue Physical loss - leakage Cost impacts at wholesale rate Tools for control include leakage and pressure management Real Losses

25 AWWA M36 Audit Data Validity Scoring In computer science, data validation is the process of ensuring that a program operates on clean, correct and useful data. AWWA developed a detailed grading matrix for Audit inputs Based on the utility s policies and practices for data collection, data management, data archiving, quality control procedures, and derivation of audit inputs Provides a quantitative measure of the reliability

26 AWWA Free Audit Software (V5.0) Data Grading for each Audit input (excerpt)

27 AWWA Free Audit Software (V5.0) Guidance on Use of Audit Data, based on Level of Data Validity Functional Focus Area Audit Data Collection Short-term loss control Long-term loss control Launch auditing and loss control team; address production metering deficiencies Research information on leak detection programs. Begin flowcharting analysis of customer billing system Analyze business process for customer metering and billing functions and water supply operations. Identify data gaps. Conduct loss assessment investigations on a sample portion of the system: customer meter testing, leak survey, unauthorized consumption, etc. Begin to assess long-term needs requiring large expenditure: customer meter replacement, water main replacement program, new customer billing system or Automatic Meter Reading (AMR) system. Audit Data Validity Level / Score Level I (0-25) Level II (26-50) Level III (51-70) Level IV (71-90) Level V (91-100) Establish/revise policies and procedures for data collection Establish ongoing mechanisms for customer meter accuracy testing, active leakage control and infrastructure monitoring Begin to assemble economic business case for long-term needs based upon improved data becoming available through the water audit process. Refine data collection practices and establish as routine business process Refine, enhance or expand ongoing programs based upon economic justification Conduct detailed planning, budgeting and launch of comprehensive improvements for metering, billing or infrastructure management Annual water audit is a reliable gauge of year-to-year water efficiency standing Stay abreast of improvements in metering, meter reading, billing, leakage management and infrastructure rehabilitation Continue incremental improvements in short-term and long-term loss control interventions Target-setting Establish long-term apparent and real loss reduction goals (+10 year horizon) Establish mid-range (5 year horizon) apparent and real loss reduction goals Evaluate and refine loss control goals on a yearly basis Benchmarkin g Preliminary Comparisons - can begin to rely upon the Infrastructure Leakage Index (ILI) for performance comparisons for real losses (see below table) Performance Benchmarking - ILI is meaningful in comparing real loss standing Identify Best Practices/ Best in class - the ILI is very reliable as a real loss performance indicator for best in class service For validity scores of 50 or below, the shaded blocks should not be focus areas until better data validity is achieved.
