Cleaning and disinfecting wastewater
LOTT treats wastewater from homes and businesses in Lacey, Olympia, and Tumwater. Wastewater contains many pollutants and must be cleaned before it is released back to the environment. LOTT cleans wastewater to a high standard – advanced secondary. LOTT’s central treatment plant is one of the only plants along Puget Sound that provides nitrogen removal as part of the treatment process.
