Auckland Council Regional Parks WTP

Auckland Council Regional Parks was operating with outdated water treatment monitoring systems that were difficult to update and maintain. Many systems were locked to specific programmers, creating significant operational risks when issues arose — including inaccurate data, phantom alarms, and delayed response times.

At the same time, the geographic spread of remote sites across Auckland’s regional parks led to high labour costs, unnecessary travel, and operational inefficiencies. Critically, the Council needed a future-proof system capable of monitoring and controlling potable water treatment processes to ensure compliance with evolving Taumata Arowai drinking water regulations.

Council teams were faced with key operational questions:

• How could they gain real-time visibility of remote sites without relying on costly physical visits?
• How could they future-proof their systems so that code updates and maintenance were no longer dependent on individual programmers?
• How could they reduce travel, labour costs, and carbon emissions while improving response times?
• How could they ensure robust, real-time compliance with Taumata Arowai standards across all sites?

Halo implemented a network of 13 advanced monitoring and control systems across the Auckland Regional Parks network, including a solar-powered installation on Great Barrier Island. The solution provides real-time, remote visibility and management of each potable water treatment plant. Halo’s in-house programmable controllers eliminate single-party dependency, allowing for continuous system updates and adaptability. The system’s remote troubleshooting capability enables operational teams to respond faster, reduce travel requirements, and ensure regulatory compliance with Taumata Arowai standards.
