Systems Rehabilitation

  Corroded Pipe

The application of infrastructure repair, renewal and replacement technologies in an effort to return functionality to a drinking water or wastewater system or subsystem. The decision-making process for determining the proper balance of repair, renewal, and replacement is a function of the condition assessment, the life-cycle cost of the various rehabilitation options, and the related risk reductions.

Research Questions

  1. Can merging and innovative sewer system rehabilitation technologies, for both sewer and non-sewer assets, include service laterals, be identified and demonstrated in field settings to improve our understanding of their cost-effectiveness, technical performance and reliability?
  2. Can approaches and methods be developed for determining the long-term performance and life-cycle cost effectiveness of various system rehabilitation technologies, including new and existing materials?
  3. Can guidance be provided for establishing a comprehensive system rehabilitation program, including rehabilitation of non-sewer assets, selection of pipe and rehabilitation materials, and testing and quality assurance of field installation and application of rehabilitation technologies?
  4. Can guidance be provided for collection system operation and maintenance programs, including procedures to assess and optimize maintenance practices that reduce the need for rehabilitation?
  5. Can sewer and collection system design guidance based on lessons learned from system rehabilitation be developed to enhance long-term performance and system integrity and to allow for easier inspection, maintenance and rehabilitation?
  6. Can a sound, risk-based, decision-making process for selecting optimal system rehabilitation technologies and methods be developed based on long-term effectiveness, system performance, structural integrity, consequence of failure, and life-cycle cost?
  7. Are decision-making processes for selecting optimal system rehabilitation technologies and methods cost-effective and do they adquat4ely address relevant factors?
  8. Can emerging and innovative pressure system rehabilitation technologies, be identified and demonstrated/verified in field settings to improve our understanding of their costs-effectiveness, technical performance and reliability?
