Renewal Engineering for Wastewater Pipelines

This report presents research intended to compile and further understand the state of the technology for wastewater pipeline renewal engineering methodologies and technologies, focusing primarily on the geographic regions of the U.S. Researchers performed an extensive literature review, covering conference papers, journal articles, vendor literature, and major reports. Additionally, detailed case studies describing utility wastewater pipeline renewal engineering practices are outlined using information data mined directly from participating utilities. The information gathered through literature review and data mining is compiled and synthesized, resulting in the presentation of conclusions regarding the state of renewal engineering of domestic wastewater pipelines, recommendations for further research and industry needs, and descriptions of identified trends. Trends in technology use and practices are summarized, cost issues are discussed, and the gaps between needs and available technologies are presented. Furthermore, this report proposes a standard data structure for utilities to use for reporting purposes when performing renewal engineering efforts on wastewater pipelines. The collection of the information presented in the proposed standard data structure for utility reporting would provide the data needed to greatly improve utility operating processes and direct research toward industry needs.
