Rehabilitation of Aging Water Infrastructure Systems: Key Challenges and Issues
Publication: Journal of Infrastructure Systems
Volume 18, Issue 3
Abstract
Presented in this paper are the results of a state-of-the-practice survey on the rehabilitation of water distribution and wastewater collection systems. The survey identified several needs, including the need for rational and common design approaches for rehabilitation systems, quality assurance/quality control procedures and acceptance testing during installation of rehabilitation systems, and decision support tools for choosing rehabilitation/rehabilitation systems versus replacement. Discussed are separate issues for water and wastewater systems in terms of drivers for increased rehabilitation efforts and problems typically encountered. Also examined are the major technologies currently in use and the major issues and key challenges faced in terms of speeding rehabilitation efforts and documenting/improving the performance of the technologies used.
