An Application of the Sustainable Asset Valuation (SAVi) Methodology to Pelly's Lake and Stephenfield Reservoir, Manitoba, Canada

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.

• The SAVi analysis of Stephenfield Reservoir indicates that maintaining the existing reservoir is significantly more cost-effective than building new grey infrastructure to provide the same water storage and irrigation services. The capital cost for new grey infrastructure is estimated at CAD 5.3 million, whereas the cost of maintaining the reservoir is CAD 256,000. Additionally, the maintenance cost for a new built asset would be approximately CAD 300,000, which exceeds current reservoir maintenance costs.
• Stephenfield Reservoir provides irrigation and water storage services that enable economic activity with a cumulative discounted value of CAD 6.07 billion by 2050.
• Pelly's Lake provides ecosystem and infrastructure services with a cumulative discounted valuation of approximately CAD 60 million between 2019 and 2050. The primary drivers of this value are nutrient removal (CAD 47,497,559) and carbon sequestration (CAD 11,925,298).
• Under climate change scenarios for Pelly's Lake, the value of flood protection increases significantly, with a discounted valuation rising from CAD 743,279 in the baseline to CAD 1,064,505, representing a 43.22% increase. However, rainfall volume has little effect on other services such as carbon sequestration, nutrient removal, and cattail harvesting.
