Work has started this week on a project to improve water quality in Elterwater.
United Utilities is installing Mobile Organic Biofilm permanently at the Langdale Wastewater Treatment Works following a 12-month trial.
It said the technology would help reduce the number of times that the Elterwater pumping station storm overflow operates.
It encourages naturally occurring bacteria to break down waste more effectively.
The technology will enable the site to treat higher volumes of wastewater and therefore reduce storm overflow operations, the firm said.
It added because it was used in conjunction with existing infrastructure, it would construction costs and minimise disruption to the local community.
United Utilities said: “During the trial, ammonia levels in treated wastewater were reduced to consistently low levels, meaning the site is already meeting new Environment Agency ammonia permit standards that are not due to come into force until 2030.”
A second project is planned to begin later this year at Langdale to reduce phosphorus levels to the lowest technically achievable limits before it is returned to the environment.
Andrew Kendall, wastewater business lead for Cumbria at United Utilities, said: “This project shows how innovation can deliver real environmental improvements.
“By installing MOB technology at Langdale, we’re already achieving future regulatory standards, and it will now help reduce the number of times that the storm overflow operates, helping to improve water quality in Elterwater and Windermere for the long term.”
