Goal 6: Clean water and sanitation
Water-conscious building standards. Apply building standards to minimise water use.
Water-conscious building standards at UniSC
At UniSC, we recognise water as one of our most precious resources and are committed to minimising water use and protecting aquatic ecosystems through innovative building design and operational practices. Our approach integrates sustainability into every stage of campus development and management, ensuring our facilities contribute to a healthier environment and resilient communities.
Integrated water management
UniSC’s Sunshine Coast campus is a model of water-sensitive urban design. Located at the low point of the Sippy Downs catchment, the campus features two lakes with a combined capacity of 130 million litres, which collect stormwater, rainwater, and wastewater runoff via swales and creeks. This untreated lake water is:
- Reused for irrigation across campus grounds.
- Treated on-site to potable standards for use in cooling towers and the central energy plant, saving over 20,000 litres of mains water daily.
Rainwater harvesting and reuse
At our Moreton Bay campus, rainwater is captured in tanks with a total capacity of 435,000 litres. This water is recycled through buildings for toilet and urinal flushing, reducing reliance on mains water and supporting circular water use.
Sustainable building design
UniSC buildings are designed to:
- Maximise natural ventilation and passive cooling, reducing the need for water-intensive HVAC systems.
- Use lightweight, low-maintenance materials that reduce water use during construction and maintenance.
- Integrate landscaping with native and drought-tolerant species, minimising irrigation needs.
Smart water systems
Our water treatment plant is equipped with:
- Glass media and ultra-filtration systems to remove particulates, bacteria, and viruses.
- A PLC-controlled system integrated into the campus Building Management System (BMS) for real-time monitoring and optimisation.
- Daily maintenance and monthly water quality testing to ensure safe and efficient operation.
Summary
UniSC’s water-conscious practices are designed not only to reduce consumption but also to protect surrounding ecosystems, including the adjacent Mooloolah River National Park. Our integrated water systems help prevent pollution, support biodiversity, and contribute to climate resilience. These practices demonstrate UniSC’s commitment to environmental stewardship and climate resilience.
