Borden Park has served the Edmonton community for over a century. While the grounds have hosted a pool since 1924, the recent update gives Canada its first chemical-free public swimming facility. The basins use a combination of natural filters that include stone, gravel, and sand along with an ecosystem of plants and microorganisms to create living water. Comprised of a children's pool, a deep pool, a sandy beach, and picnic areas, the recreation pavilion is contained by dark limestone gabions. These rocky barries also form a pool house that includes outdoor showers and changing rooms. While its low profile resembles the site's existing mid-century buildings, it also allows for views of the tree canopies above, enhancing the experience of swimming in the middle of nature.
