Noman Cole UV Disinfection Project Featured in TPO Magazine

The change to UV disinfection is expected to improve operations in several ways, including greater safety for workers and the community, reduced labor and maintenance costs, and less use of chemicals.

Hazen uses HoloBuilder which enables users to create immersive 360° virtual tours that resemble Google Street View. Using HoloBuilder’s Job Walk app, users can annotate 360° photos with relevant documents and close-up images of equipment.

Plant operators and engineers wearing 3D Oculus goggles experienced three-dimensional views of the work spaces before construction. This enabled modifications that could save money or reduce future maintenance. It was the first public works project in the county to use the technology.

(FAIRFAX, VA - February 8 2021) - The UV disinfection project at the Noman M. Cole Jr. Pollution Control Plant in Fairfax County, VA was recently highlighted in the latest issue of TPO (Treatment Plant Operator) Magazine.

The change to UV disinfection is expected to improve operations in several ways, including greater safety for workers and the community, reduced labor and maintenance costs, and less use of chemicals. Although the process will require more electricity, the plant’s carbon footprint will be reduced if carbon reductions from chemical manufacture, transportation and storage are counted.

County staff worked with the designers (Hazen and Sawyer) and the construction contractor (Ulliman Schutte Construction) in a construction-management-at-risk project delivery method that encourages collaboration and teamwork. The method allows early input from the construction manager, and in this case that led to some design improvements and an increase in salvageable material.

Another innovation in design for the UV system was the use of mixed-reality technology. Holographic images of new elements were superimposed on existing spaces to help the design team better understand the work environment being created.

Plant operators and engineers wearing 3D Oculus goggles experienced three-dimensional views of the work spaces before construction. This enabled modifications that could save money or reduce future maintenance. It was the first public works project in the county to use the technology.

The new disinfection system is expected to go online in March. The project previously earned a 2019 Envision Gold Award for Sustainability from the Institute for Sustainable Infrastructure.
