Cresta Shopping Centre in Gauteng sought a strategic solution to reduce escalating water usage across its high-traffic washrooms. Traditional 9-litre toilets were driving excessive consumption and high utility bills. In 2024, the centre installed 114 Propelair toilets using only 1.5 litres per flush. This shift immediately reduced water usage by 83%, saving an estimated 22.5 million litres annually and delivering more than R2.1 million in yearly cost savings with a rapid 15.6-month payback period.
Client Profile
Cresta Shopping Centre is a major retail destination in Gauteng, accommodating thousands of visitors daily. As a large commercial building with extensive public washrooms, water efficiency plays a crucial role in reducing operational costs and maintaining environmental responsibility. With increasing pressure on South Africa’s water infrastructure, Cresta required a sustainable, reliable solution that would strengthen its long-term ESG performance.
Challenges / Pain Points
Before adopting Propelair, Cresta Shopping Centre faced several operational and financial challenges associated with high water usage caused by outdated 9-litre flush systems. These inefficient toilets significantly inflated water bills and placed unnecessary strain on municipal supply. As a busy commercial environment, the centre also experienced typical commercial washroom issues, including increased maintenance requirements, hygiene concerns, and vulnerability to blockages and downtime. Rising utility costs, sustainability expectations, and the need for long-term cost control added further pressure. A modern, efficient, and low-maintenance upgrade was essential.
The Propelair Solution
To address these challenges, Cresta Shopping Centre installed 114 Propelair high-performance toilets across its washrooms. Propelair technology uses a powerful air-assisted flush, allowing each unit to operate with only 1.5 litres per flush, a significant improvement from the previous 9-litre systems. Key features—such as triple hygiene protection, reduced splashback, and lower aerosolization—enhanced user safety and cleanliness. The system’s robust engineering is designed for commercial environments, ensuring durability and consistency during peak footfall. Installation was straightforward, requiring minimal disruption thanks to Propelair’s retrofit-friendly design. This upgrade equipped Cresta with a sustainable washroom solution that reduces consumption while improving operational efficiency.
