Lunner Municipality Adopts AI for Smarter Wastewater Treatment – Powered by Guard Technology

Using a cloud-based system powered by artificial intelligence, the municipality can optimize wastewater treatment processes in real time. Developed by Sandefjord-based Guard Automation, the technology analyzes wastewater composition and automatically adjusts chemical dosing according to actual treatment needs.

”Ensuring clean water for people and the environment is a fundamental responsibility that we take very seriously. That is why we are investing in smarter solutions that improve operations while reducing costs,” says Eivinn Arnold Fjellhammer, Head of Planning and Community Development at Lunner Municipality.

Better Treatment with Fewer Chemicals

Guard Treat Smart uses artificial intelligence to analyze real-time process data and historical patterns, enabling more precise chemical dosing. The result is more stable operations, reduced chemical consumption, and less need for manual intervention.

”Many wastewater treatment plants dose chemicals based on total water volume rather than the actual amount of pollutants that need to be removed. Our system uses existing data to optimize dosing according to actual treatment requirements,” explains Caroline Haglund, Business Developer AI at Guard Automation.

Turning Data into Better Decisions

Beyond optimizing chemical consumption, the technology provides the municipality with valuable insights into its wastewater infrastructure.

”We can make more informed decisions about whether to invest in additional treatment capacity or prioritize improvements to the sewer network. The data also helps us document the impact of measures taken to protect water quality,” Fjellhammer explains.

He emphasizes that wastewater challenges extend beyond municipal boundaries.

”The water we treat is discharged into local rivers that eventually flow into the Oslofjord. That is why we need to look beyond individual facilities and take a broader, more integrated approach to water and wastewater management.”

Potential Beyond Norway

Seven Norwegian municipalities have already adopted the technology, reporting promising results: chemical consumption reductions of 20–30%, more stable operations, and fewer manual adjustments.

Guard Automation also sees significant potential beyond the Norwegian market.

”The technology is already being used in Sweden, and we see a growing global need for smarter, more sustainable wastewater treatment,” says Haglund.

She also highlights the importance of municipalities willing to explore and further develop new solutions.

”Municipalities like Lunner, which actively test and help refine the technology, provide us with valuable operational insights. This ensures that our solutions are not only technically capable, but also work in practice and address real operational needs.”
