Not new, and that is the point
Routing treated wastewater through filtration and UV disinfection into a lagoon is a well-established approach used at international parks. It is not novel, and we do not claim it is.
Standards for human contact
Water in the proposed lagoon would be treated to meet recognised safety standards for recreational human use, with continuous monitoring. Final specifications depend on engineering studies not yet commissioned.
The wider target
The campus targets solar-led supply with backup generation, and 70-90% recycled material content. These are targets, not commitments, until design is complete.
