The City of Winnipeg retained Associated Engineering to assess options and provide a solution to rehabilitate or replace an aging feedermain crossing - the 40-year-old, 600 millimetre diameter, North Kildonan Feedermain, which crosses the Red River. Connecting to the northeast and northwest sections of the City’s water distribution network, the feedermain is a critical component of the City’s water infrastructure.
Various options were evaluated, considering constructability, operation and maintenance, social impact during construction, sustainability, infrastructure security, construction schedule, regulations, and the environment. Based on the criteria and assigned ratings, the team recommended that the feedermain be replaced with a new pipe, installed by horizontal directional drilling.
The City accepted the recommendations, and retained Associated Engineering to provide contractor prequalification, detailed engineering, contract administration, and resident engineering for the design of the new pipeline across the Red River. This work also included connecting the crossing to the existing feedermain on the east and west sides of the river, which was completed under a separate construction contract.
