Cities can re-use treated greywater for toilet flushing, irrigation, and cleaning. This eases pressure on municipal supplies and extends the lifespan of critical infrastructure. Developers adopting these systems early are future-proofing their assets and gaining ESG traction.

Industries require large amounts of water for cooling, processing, and cleaning. By implementing water re-use systems, industries can significantly reduce their freshwater intake, lower operational costs, and minimise their environmental footprint.

In regions facing chronic water stress, treated wastewater offers a stable irrigation alternative. Its nutrients can even improve soil health, reducing the need for synthetic fertilizers. Smart reuse also ensures water availability during drought periods, increasing agricultural productivity sustainably.

Power plants, particularly those reliant on cooling cycles, are large water consumers. By integrating reuse systems, these facilities can reduce their intake of freshwater by up to 50%, making them more sustainable and less vulnerable to regional shortages.
For years, onsite water reuse systems were sidelined, because South Africaâs regulatory framework hadnât caught up with global innovation. Decentralised systems, despite meeting rigorous international standards, were treated as fringe solutions in a country still tethered to centralised infrastructure models.
That has officially changed.
This is a game-changing development. It means that decentralised water reuse systems are now a legitimate, approved pathway for meeting water needs legally and sustainably. It unlocks the door for widespread implementation in estates, commercial developments, industrial facilities, and agricultural zones.
But recognition is only the first step. The urgency to adopt has never been greater.
Waiting is no longer an option.
We now have the regulatory clarity, the proven technology, and the operational models in place. The responsibility shifts to developers, property owners, and decision-makers to act, not only to ensure water security but to build sustainable, future-proofed assets.
