This report applies the Sustainable Asset Valuation (SAVi) methodology to two infrastructure assets in Manitoba, Canada: Stephenfield Reservoir (a built asset) and Pelly’s Lake (a natural wetland). The study quantifies the economic value of the ecosystem and infrastructure services they provide and compares these to the costs of replacing those services with grey infrastructure. The findings demonstrate that both natural and naturalized built assets are significantly more cost-effective than traditional grey infrastructure for water storage, irrigation, and nutrient removal.

This fact sheet describes the application of the Sustainable Asset Valuation (SAVi) methodology to two assets in Manitoba, Canada: Stephenfield Reservoir and Pelly's Lake. The assessment compares the costs of maintaining these natural and built assets against the capital and operational costs of replacing their services with 'grey' (engineered) infrastructure, while simulating baseline and climate change scenarios from 2019 to 2050.
