UV Disinfection
Ultraviolet (UV) disinfection integration for municipal and industrial water treatment systems.
Proven, Powerful and Chemical-Free
With more than 140 years of construction and engineering expertise, Kiewit has delivered critical infrastructure projects that support safe, sustainable water systems across North America. Our teams bring firsthand experience with integrating ultraviolet (UV) disinfection into municipal and industrial water treatment systems, delivering solutions that meet strict regulatory standards and protect public health.
What is UV Disinfection?
UV disinfection is a chemical-free, highly effective solution that neutralizes harmful microorganisms without producing toxic byproducts. It operates quickly, requires minimal contact time and is effective against chlorine-resistant pathogens like Cryptosporidium and Giardia making it a vital component in modern water treatment strategies. It can be used for treating both drinking water and wastewater. For wastewater, it eliminates the discharge of chlorine into the environment and supports land application reuse.
What Should You Consider?
For drinking water, UV disinfection doesn’t leave residual pathogen protection in treated water, so systems must be properly managed to prevent recontamination and provide residual chlorine for point-of-use protection. Water clarity also matters; turbidity and suspended particles can block UV light from reaching pathogens, so pretreatment processes should be part of any UV system.
The Kiewit Advantage for UV Disinfection Solutions
As one of North America’s largest and most respected construction and engineering organizations, Kiewit delivers turnkey solutions for water treatment. From early contractor involvement through startup, we bring integrated expertise to reduce cost, risk and schedule.
Northwater Treatment Plant
Kiewit replaced an operational WTP with a new 75 MGD facility expandable to 150 MGD. It includes a new headworks facility with a hydro turbine, flocculation and sedimentation basins, anthracite media filtration with UV disinfection and more. By introducing UV into the treatment process, the need for a disinfection contact basin was eliminated and replaced by a buried, 120-inch diameter contact pipeline, which led to less overall concrete needed on the project.
