The Westside Irrigation Rehabilitation Project (WIRP) in Saskatchewan is projected to increase the province's GDP by $12.9 billion, create 80,000 jobs, and generate $1.3 billion in taxes. The project includes the West Side pump station, main canal, Conquest reservoir, and distribution system, with an estimated rehabilitation cost of $1 billion for 100,000 acres.

As of November 2025, design steps are underway, with major construction expected to begin in spring 2026. KPMG's analysis highlights that 40% of the economic impact will be felt outside the immediate project area.

Future expansion in food manufacturing, crop growth, and irrigation equipment purchases are identified as key GDP drivers. A planning study around Lake Diefenbaker aims to promote irrigation expansion, identifying nine zones for potential development, which may include costly infrastructure improvements to sustain agricultural operations.
