Tararua District Council has multiple SCADA systems for its water and wastewater treatment plants. Network telemetry is also hosted elsewhere and facilitated by the Tararua Alliance. The siloed and disparate systems lead to poor monitoring of the daily operations and control of the water and wastewater plants and networks. Compounding the operability issues of these systems, the communications network often has disruptions that result in a need for manual resetting and may lead to operational non-compliance.

Due to the vulnerability of the SCADA and telemetry system we require a new framework and architecture for the system. This should involve an evaluation and development of an improved human interface (faceplates), software, hardware and (subject to a future RFx) ongoing support through an SLA agreement.

Tararua District Council would prefer to reuse existing infrastructure as far as practical and relocation and reconfiguration of some telemetry equipment where required to fulfil reactionary needs. It is also expected that the final framework and architecture will provide for laying the foundations for an appropriate SCADA and telemetry system, that with investment, can meet the any future operational and/or regulatory needs.
