Spotted Lake located near Osoyoos, British Columbia has one of the highest mineral concentrations in the world. Appropriately named for its appearance, the unusual qualities of the lake are a result of massively high concentrations of salts, titanium, calcium, sulphates and other minerals that form “walkways” around pools.

Fog interception technology copies the function of trees and other natural features using polypropylene mesh nets. The mesh captures water droplets which trickle into a collection trough and drain into a series of tanks. The average collection is 150 to 750 litres per day but some schemes are capable of producing 2,000 to 5,000 litres per day.
