Rainwater filtration System

Through a network of tubes and pipes, sanitary rainwater is transported throughout the building to the bathrooms, the washing machine, the local circular bio-based material production unit of the Knotfactory, and the garden. Blue and white lines on the floor and ceiling trace the paths that water takes throughout the building. Sanitary rainwater is represented by medium-blue colored lines, city water is represented by white lines, and unfiltered rainwater is represented by dark-blue lines. Roughly half of the water used in Timelab’s building is now sanitary rainwater. In Timelab’s Waterlab, there is a gold sink with a faucet for drinkable rainwater and a second faucet for sanitary rainwater. Visitors are welcome to drink the drinkable rainwater and wash their hands in the sanitary rainwater.

Sanitary rainwater is made by filtering rainwater through activated carbon, limestone, and UVC light.

Drinkable rainwater is made by filtering rainwater through activated carbon, limestone, UVC light, an ultrafiltration membrane with extruded activated carbon, and reverse osmosis.

Wastewater from the filtration system is pumped to Timelab’s garden and the city sewer system. From the garden, the wastewater infiltrates into the groundwater or plants transpire it back into the atmosphere. From the city sewer system, it goes to the Ossemeersen Wastewater Treatment Plant, then into Gent’s canals, the Schelde River, the North Sea, and ultimately the Atlantic Ocean.
