The Propelair installation resulted in an 83% reduction in water usage, saving approximately 22.5 million litres every year. By replacing 9-litre flush units with 1.5-litre technology, Cresta achieved a dramatic drop in consumption while ensuring improved washroom performance. This transformation positions the centre as a leader in sustainable water management within the retail sector.

With water consumption significantly reduced, Cresta Shopping Centre now saves more than R2.1 million annually. The investment delivered a rapid 15.6-month payback, making it financially compelling as well as environmentally impactful. Reduced maintenance requirements—due to fewer blockages, less wear, and improved hygiene—further extend the centre’s operational savings.

The installation supports Cresta’s ESG goals by reducing pressure on local water infrastructure and lowering energy-related carbon emissions associated with water treatment. The significant annual water savings translate into meaningful carbon reduction, contributing to climate responsibility, improved sustainability reporting, and enhanced overall environmental performance.
