Courtyard water storage
26,000L of rainwater storage will sit beneath the central courtyard, collecting water from the rear roofs and through the soil. The excavated site is lined with plastic, filled with modular polypropylene units and covered with geofabric, then sand and soil. All three elements have 100% recycled content. The water will be used for garden irrigation and swimming pool top up. The installation of this water storage will be completed this afternoon and once covered, will be fully trafficable (though in reality, only foot traffic will pass over it when the building is complete).
There will still be another 46,000L of rainwater storage beneath the front driveway dedicated to household supply.
