CLIENT: Regional District of Okanagan-Similkameen
PROJECT DESCRIPTION:
The Regional District of Okanagan-Similkameen (RDOS) retained PRI to deliver the Naramata Water System Rehabilitation and Extension Project. Awarded in December 2016 and completed by the end of November 2017, the project involved watermain replacement across eight roads in Naramata. PRI’s scope encompassed detailed topographic survey, engineered design drawings, MMCD tender document preparation, materials testing, QC/QA, and full construction services.
CHALLENGE:
The aging water system required comprehensive rehabilitation across multiple roads simultaneously, presenting coordination challenges across a broad project area. The design needed to account for updated fire protection requirements and appropriately sized watermains determined through hydraulic modelling and calibration. Working within road allowances also required engagement with the Ministry of Transportation and Infrastructure (MOTI) as the approving authority for all proposed road and stormwater improvements. Additionally, site conditions on certain roads demanded innovative installation methods to minimize disruption to existing infrastructure and road surfaces.
APPROACH:
PRI managed all phases of the project from survey through construction. Design work included site surveys, base map preparation, and hydraulic modelling and calibration to determine watermain sizing and fire protection requirements. Coordination with MOTI was maintained throughout the design development process. PRI prepared platinum MMCD tender documents, including a detailed Schedule of Quantities and Unit Prices, and conducted materials quality control and quality assurance testing on all structural fill and pavement structure. Where site conditions warranted, innovative construction techniques were employed, including slip lining and pipe bursting to install new watermain inside existing pipes, and auguring of water services beneath Naramata Road to preserve the existing asphalt on the west side of the road.
OUTCOME:
The Naramata Water System Rehabilitation and Extension Project was completed on schedule by November 2017, delivering a modernized water distribution system across eight roads. The use of trenchless technologies such as slip lining, pipe bursting, and auguring minimized surface disruption and preserved road integrity where conventional open-cut methods would have been impractical. PRI’s full-service delivery, from survey and design through tendering, construction oversight, and materials testing, provided the RDOS with a seamless, single-point-of-accountability engagement throughout the project.
