Waiari Water Treatment Plant

Challenge

McKay began by conducting a thorough assessment of the project requirements and specifications provided by Fulton Hogan, on behalf of Tauranga City Council. They then formulated a detailed plan to address each aspect of the electrical system and solar installation.

For the electrical supply, McKay installed 500kVA mains, 400V 1600A dual redundant MGE Main Switchboards along with DOL/VSD Sub Services. They also implemented a 750kVA Backup Generator with an Automated Transfer System to ensure uninterrupted power supply.

To meet the requirements of the water treatment plant, McKay provided the necessary infrastructure for water and sludge storage, pumping systems, HVAC Sub Services, and process measurement and control. They also installed the required equipment for chemical storage, dosing, and analysis.

For effective control and automation, McKay employed an Allen Bradley Controllogix Main PLC with Festo Integrated Remote IO & Pneumatics. They also implemented a Dali Automated Lighting Control system, Galaxy Wifi Emergency Lighting, Assa Abloy Automated Windows based on McKay Design, as well as the Integriti Site Access Control System and CCTV cameras for security.

In addition to the electrical components, McKay designed and installed a solar package for the water treatment plant. They carefully selected the appropriate solar modules and panel racking/support structures to create a 120kW capacity photovoltaic system.

Outcome

By successfully executing the project, McKay ensured the Waiari Water Treatment Plant had a reliable, efficient, and secure electrical supply and control system. The installation of the solar photovoltaic system added a sustainable source of renewable energy, reducing the plant’s reliance on traditional power sources.

The comprehensive electrical infrastructure, including the backup generator, ensured uninterrupted operations during power outages or emergencies. The control systems, lighting automation, and access control system provided enhanced security and streamlined operations.

Overall, McKay’s expertise in electrical system design, installation, and implementation, coupled with the integration of a solar photovoltaic system, contributed to the successful completion of the water treatment plant project. The Waiari Water Treatment Plant now plays a crucial role in providing clean and reliable water supply to the Bay of Plenty area, showcasing the positive outcome of McKay’s work in the community.
