Buffalo Pound Non-Potable Water Supply System Regina Regional Pipeline

The Buffalo Pound Non-Potable Water Supply System (BPNPWSS)–Regina Regional will supply non-potable water from Buffalo Pound Lake to industrial customers around Regina. The Regina Regional System is an extension of the existing BPNPWSS–East that currently supplies non-potable water to industrial customers in the Belle Plaine corridor. The planning of the pipeline began with utilizing GIS to show existing constraints. Once the route was chosen, hydraulic analysis was completed to determine the required pressure rating and diameter of the pipe to deliver the required water to the end users. The design of the pipeline took a unique and alternative delivery approach. The design of the pipeline was completed to 80% without a specified pipe type for procurement. A Request for Supplier Qualifications (RFSQ) pre-qualified three contractors to submit a proposal to complete the work. The proposals included the contractor’s proposed pipeline material for each section meeting the specified criteria, work plan and schedule, additional details on their previous experience, and their proposal price. Once the pipe types were chosen, the design was completed with the selected contractor’s input and construction began in May 2023. This paper will provide an overview of the planning and design process determining the pipeline route utilizing GIS, to 80% design of the pipeline, and finally to obtaining a qualified contractor and completing the design and construction. We will also discuss the challenges and benefits that this approach brought on.
