Suppliers make progress implementing critical treatment barriers

The Water Services Authority - Taumata Arowai, has been monitoring the progress of 29 council and two government drinking water suppliers as they’ve developed funded plans to implement critical drinking water treatment barriers by December 2025.

In October and November last year, Taumata Arowai advised suppliers with supplies lacking protozoa, bacterial, or residual disinfection treatment barriers of its expectation that by 30 June 2024 they provide a funded plan for implementing these barriers.

Since then, these suppliers have sought to identify cost-effective options to get these drinking water treatment protections in place.
