The 2020s are challenging our urban systems with bushfires, floods and drought. Working with natural systems is a key to future planning as our current infrastructure is not designed for future challenges.
Designing at the building scale creates opportunities to address water demand, stormwater risks, waterway health, urban greening and resilience to disasters. The BASIX program in NSW relies heavily on rainwater harvesting and has shown system wide benefits that go far beyond saving water.
Using rainwater from your roof is more efficient than manufacturing water, treating it to a drinking standard, pumping it across the city and using that water to flush a toilet. Rainwater harvesting is a good example of a low cost, nature friendly solution integrated with land use planning and building frameworks.
