Impact/Purpose:
As U.S. utilities continue to shore up their aging water and wastewater infrastructure, renewal needs now represent over 43% of annual expenditures compared to new construction (Underground Construction [UC], 2016). New trenchless renewal technologies continue to come to market and improvements in existing technologies are ongoing. An increased understanding of these new renewal options will ultimately assist drinking water utilities to optimize their choices for reducing water loss and help wastewater utilities to optimize their choices for addressing infiltration and inflow issues in a cost-effective manner. To support information sharing, the U.S. Environmental Protection Agency (EPA) supported this research effort for the collection of case studies on the use of trenchless pipeline renewal methods. This task also created a Web-based, searchable database that utility personnel can use to obtain technology performance and cost data.
Description:
As U.S. utilities continue to shore up their aging infrastructure, renewal needs now represent over 43% of annual expenditures compared to new construction for drinking water distribution and wastewater collection systems (Underground Construction [UC], 2016). An increased understanding of renewal options will ultimately assist drinking water utilities in reducing water loss and help wastewater utilities to address infiltration and inflow issues in a cost-effective manner. It will also help to extend the service lives of both drinking water and wastewater mains. This research effort involved collecting case studies on the use of various trenchless pipeline renewal methods and providing the information in an online searchable database. The overall objective was to further support technology transfer and information sharing regarding emerging and innovative renewal technologies for water and wastewater mains. The result of this research is a Web-based, searchable database that utility personnel can use to obtain technology performance and cost data, as well as case study references. The renewal case studies include: technologies used; the conditions under which the technology was implemented; costs; lessons learned; and utility contact information. The online database also features a data mining tool for automated review of the technologies selected and cost data. Based on a review of the case study results and industry data, several findings are presented on trends in the water and wastewater renewal market and opportunities for future improvements.
