At the 2025 AWA NSW Conference, Emma James, Segment Lead, Recycled Water, Growth & Development at Sydney Water, presented the outstanding results achieved from the RegenAqua Facility at Picton, developed in partnership with Pacific Bio.

🌿 Over 30 months of operation, RegenAqua delivered proven, nature-based treatment performance:

✅ 99–100% removal of Ammonia-N
✅ 95–98% removal of Soluble Reactive Phosphorus
✅ Oxidised Nitrogen reduced to near-zero in longer-residence-time ponds
✅ 90–95% reduction in microbial indicators (E. coli, Enterococci, Faecal Coliforms)
✅ 40–80% removal of key metals (residence-time dependent)

RegenAqua is low-energy, chemical-free, and circular, a scalable, sustainable approach to tertiary wastewater treatment that protects sensitive waterways and ecosystems.

This extended Sydney Water deployment shows how utilities can achieve high-performance nutrient removaland enable future water reuse through a nature-based solution.

🌏 Proven in Australia. Deployable globally.
