Groundwater is accessed 02. Water is used in toilets, sinks and for cleaning 03. The used water - a combination of grey and black water, is collected in two 19,000 Litre anoxic tanks, located underground. Here, “naturally occurring microbial organisms use the wastewater as food. They digest ammonia, phosphorus, nitrogen, potassium, and many other substances in the water.” (Omega, 2019) 1 03.a Biogas (a waste bby product of the anerobic processes that breakdown waste materials) is siphoned from the anoxic tanks. This is fed to a generator onsite to produce energy for the pavilion 04. From the anoxic tanks, the water flows to four man-made wetlands. Approximately 900mm deep, lined with rubber and completely filled with gravel. Wastewater flows about 5cm under the surface, stopping evaporation. Microorganisms and native plants, including cattails and bulrushes “reduce biochemical oxygen demand, remove odorous gases, continue the denitrification process and harvest nutrients such as phosphorus.” (Omega, 2019) 1 05. Two aerated lagoons, containing four cells each and about 3m deep, utilise tropical plants as filters. “At this stage, the water looks and smells clean, but it's not safe to touch. The plants, fungi, algae, snails, and other microorganisms convert ammonia into nitrates and toxins into harmless base elements”. (Omega, 2019) 1 06. The final treatment stage uses a recirculating sand filter. Here, sand and microorganisms absorb and digest remaining fine particulates and nitrates that may be present. At this stage the treated water is drinkable standard, without using any chemicals. 07. Testing of the water quality is done at this stage to ensure it is in the best possible condition before being released into the groundwater table 08. Water is taken back through the purification process if it does not meet standards at the testing point. 09. The purified water is released back into the groundwater table, where the process can begin again. 01 09 Diagram _ Closed-loop water treatment system 20 20 17.5 1. Omega. (2019).
