Oak Harbor Clean Water Facility EI&C Design and SCADA Integration and Programming

When the City of Oak Harbor set out to build a new water reclamation facility, it faced a unique challenge: the selected site was Windjammer Park, one of the community’s most cherished public spaces. The project needed to do more than deliver high-quality wastewater treatment, it had to preserve scenic views, maintain public access, and blend seamlessly into the park environment, all while providing long-term operational reliability.

Carollo partnered with the City to provide a comprehensive suite of services that included electrical, instrumentation, and control (EI&C) design, SCADA integration and programming, and development of a fully networked system designed for both efficiency and durability.

The facility features a smart power system that enables real-time energy monitoring by process and asset, allowing operators to make more informed decisions to optimize performance. The electrical design also supports proactive maintenance through a data-rich configuration that helps identify emerging issues before they lead to equipment failure or costly downtime. To support secure and reliable operations, Carollo procured, tested, and installed the plant’s core networking racks, connecting PLCs, SCADA, business systems, fire alarms, and security features via a high-speed fiber network.

Throughout the project, Carollo worked closely with the City and the broader design team to integrate the new facility into the park’s layout without disrupting the character of the space. The result is a treatment plant that quietly supports public health and environmental stewardship while respecting the park’s recreational value and natural landscape.

By combining technical excellence with thoughtful site integration, the City of Oak Harbor and Carollo delivered a solution that serves both the utility and the community. The result is a high-performing facility that enhances the resilience of Oak Harbor’s infrastructure while contributing to the vibrancy of its public spaces.
