Wastewater? Water Wealth!!!

Heavy rainfall caused Rozelle Bay water logging already, because of regional limited drainage system and impermeable mode of construction. In the future, extreme weather and global climate change will stormwater issues. Polluted water will bring contamination in soil flowing into bay, cause sea water pollution, then it’s an ecosystem vicious circle. Developing storwater management design based on sponge city strategy The design is divided into three parts - Urban area (Collection and storage stormwater by green roof, permeable surface, underground water storage system), Urban waterfront (Combining rainwater journey with promenade; give back the waterfront for public; Enhancing interaction with water; reusing rainwater and Improve urban climate and storm water resilience) and Ecological area (Celebrating indigenous mangrove habitat; Reduce contamination polluting the bay). The design will focus on the advantages of creating urban and landscape infrastructure that treats, exposes and celebrates the storm water. It would enhance the residents understanding and appreciation of storm water, it would improve urban heat island impacts and would flow through a range of waterscapes to the mangroves then reach the bay. Stage 1: Infrastructure construction (pavement, permeable street, water tank underground, maritime area relocated). Stage 2: water features and tidal stair Mangrove habitat set up (people play with fresh water). Stage 3: Public activity space, healthy mangrove habitat intertidal zone, absorb contamination, clean sea water (people interacted with waterfront).
