The natural swimming pool in Borden Park in the Canadian metropolis of Edmonton in the province of Alberta has become a new summer attraction with its completion. The friendliness and hospitality of Canadians is as impressive as the natural landscape in the nearby Rocky Mountains. A great family pool with very clear shapes and structures. The dark Limestone-granite combined with the steel gabions of the wooden decks makes for a beautiful aesthetic-technical look. Surrounded by a beach, a large lounge with sunbeds and umbrellas are laid in the two separate swimmer and non-swimmer pools. The inlet section is formed by the entry building, which has been kept entirely in the gabion/steel look of the Neptune filter.

The water is heated with a local heating system. Edmonton’s continental climate causes average temperatures to fluctuate between 28.6 °C throughout the year between the warmest month of July and the coldest month of January. Therefore, special measures to protect the pipelines against frost in winter had to be taken into consideration during the planning phase. There were also several rounds of consultations with the Canadian health authorities, as Borden Park was the first public outdoor pool with man-made biological water treatment in the North American area at that time.

UV lamps for hygiene purposes were used as an additional feature to our standard aquaculture and Neptune filters.

The technical water treatment

The water treatment for the public swimming pool in Edmonton is based on the German FLL guidelines for natural swimming pools. The nominal number of daily swimmers at the Borden Park Pool is about 1000 people.
The water treatment works with gravel filters and planting zones fed in closed water circuits to remove suspended solids, germs and phosphorus. Phosphorus removal is a basic measure to reduce the growth of algae and weeds.
The pool water is taken out of the pool through an infinity edge. From here, the water runs into the used-water shaft. From this shaft, two pumps deliver water to the various water treatment units.
The pool water pumps, located in the technical building, deliver the water into the Neptune filter. There, the water is distributed over the filter surface via nozzles and then filtered through a gravel filter bed. On the surface of the gravel there is a living biofilm that binds algae and germs, thus purifying the water.

Today, Polyplan monitors the system through the DANA platform and provides on-site background services to pool operators.
