Thinking Outside the Pipe: Comparison of Non-invasive, Non-destructive Condition Assessment Technologies

Objectives

• To provide utilities with a better understanding of the benefits and limitations of low-cost, non-invasive pipeline condition assessment technologies and how they may be applied to make better distribution pipeline renewal/replacement decisions.
• To examine “false positives” and “false negatives” in estimating the limitations of these technologies.

Research Approach

• The research team that provides the best approach to this subject (within budget constraints) will be selected. The following tasks are suggested for consideration:
  • Critically review published literature and research reports, including literature provided by the technology companies, particularly validation studies.
  • Prepare a test pipeline matrix composed of pipe segments with variable conditions to test how readily differences can be detected across pipe diameters and materials.
  • Arrange for comparative field testing of low-cost, non-invasive pipeline condition assessment technologies, ideally in various geographical areas of the country representing different burial, soil, and service conditions.
  • Validate positive findings of anomalous conditions identified by application of these technologies at various water utilities:
    • Excavate the pipeline at the anomalous condition and other location(s) to compare results.
    • Compare the results from these technologies with results from reliable high-resolution methods performed on the same pipelines.
    • Compare the results to historical maintenance data, such as previous repairs.
    • Any other innovative methods to validate findings.
  • Prepare a study report that summarizes the research, findings, and suggestions for application and limitations (particularly resolution) of each technology, as well as future research.

Funding Information

• The maximum funding available from WRF for this project is $250,000. The applicant must contribute additional resources equivalent to at least 33% of the project award. For example, if an applicant requests $100,000 from WRF, an additional $33,000 or more must be contributed by the applicant. Acceptable forms of applicant contribution include cost share, applicant inkind, or third-party in-kind that comply with 2 CFR Part 200.306 cost sharing or matching. The applicant may elect to contribute more than 33% to the project, but the maximum WRF funding available remains fixed at $250,000. Proposals that do not meet the minimum 33% of the project award will not be accepted.
• The anticipated period of performance for this project is 24-36 months from the contract start date

Expected Outcomes

• Final report summarizing the findings of the project and suggestions for future research.
• Webcast to share project outcomes with water utility professionals.

Eligibility Criteria

• Proposals will be accepted from both U.S.-based and non-U.S.-based entities, including educational institutions, research organizations, governmental agencies, and consultants or other for-profit entities.
• WRF’s Board of Directors has established a Timeliness Policy that addresses researcher adherence to the project schedule. Researchers who are late on any ongoing WRF-sponsored studies without approved no-cost extensions are not eligible to be named participants in any proposals.
• WRF encourages participation from water utilities and other organizations in WRF research. Participation can occur in a variety of ways, including direct participation, in-kind contributions, or in-kind services.

Evaluation Criteria 

• The following criteria will be used to evaluate proposals:
  • Understanding the Problem and Responsiveness to RFP (maximum 20 points)
  • Technical and Scientific Merit (maximum 30 points)
  • Qualifications, Capabilities, and Management (maximum 15 points)
  • Communication Plan, Deliverables, and Applicability (maximum 20 points)
  • Budget and Schedule (maximum 15 points)
