  1. An Overview of the WERF Condition Assessment Protocols Project Tony UrquhartMay 5, 2005

  2. WERF Research Project Research Priorities for Successful Asset Management, March 2002 • “Develop protocols for the assessing the condition and performance of water and wastewater infrastructure assets and develop predictive models for correlating asset condition and performance”

  3. Project Objectives • Identify and document available tools and techniques • Provide guidance on incorporating into utility management philosophy • Water & wastewater treatment, collection, and distribution

  4. Project Scope • Research available tools • Identify practices from other industries • Identify best applicable practices • Phase 1 Phase 2 • Develop a programmatic approach for condition and performance assessment (schedule, resource needs) • Provide case studies with positive cost justifications • Identify areas for future research

  5. Core Project Participants • ProjectSponsors • WERF • EPA • AWWARF • Team Members • TAG • CSIRO • E2 Consulting WERF Members • City of Bellevue • Northeast Ohio Regional Sewer District • Watercare (NZ) • Water Corporation of Western Australia

  6. Becoming a Project Participant Typical examples are: • Commitment of expertise in condition assessment • Commitment to a defined quantity of research hours • Access to case studies and condition assessment data Making a commitment to participate: • Commitment is in-kind • Written commitment defining hours, people and data is required
