AbstractThe Region of Ottawa-Carleton chose the trenchless sliplining method to renovate its 915-mm (36?) diameter cast iron watermain under Gloucester Street, one of the busiest streets in downtown Ottawa. This paper describes the research aspect of this project, which comprises a performance assessment and implementation of performance monitoring instrumentation in the field. The performance assessment was carried out to obtain stresses under different loading and thermal conditions and service life expectancy. Both grouted and ungrouted options were evaluated and compared. Laboratory testing of specimens taken from an old cast iron pipe, a high density polyethylene (HDPE) pipe segment and grouted sliplined pipe sections were conducted. The assessment showed that a grouted pipe should perform better. The second part describes the methods for the field installation of sensors on the two pipe materials and the challenges of protecting the sensors during insertion process and completing the installation within the constraints and schedule of the contract work. A layout of the complete instrumentation, datalogging and communication system is presented.
