Clusia Cove is a three-hectare closed-loop water recycling system for use at the Water Playground.
The cleansing biotope serves as a natural water treatment system. The biotope consists of a series of cells containing sand beds that filter out particulate matter, as well as semi-aquatic plants which absorb excess nutrients from the water.
The water then filters through the cells into an underground ultraviolet (UV) room where it is disinfected by UV treatment before being pumped to the Water Playground. At the playground, children can experience water movements that mimic tidal patterns, surface ripples and directional currents similar to those at coastal shores.
