LOTT Receives $1.1 Million Incentive from Puget Sound Energy


Lacey, WA – LOTT Clean Water Alliance (LOTT) was awarded a $1.1 million conservation grant from Puget Sound Energy (PSE). The funding recognizes energy savings resulting from a recent process improvements project at the Budd Inlet Treatment Plant. Parametrix partnered with LOTT throughout the project.

“Parametrix has worked with LOTT on several projects since the 1980s, and together, they have developed a team delivery process that has been instrumental in the success of complex projects at the treatment plant. They were skilled at leading the team through the recent process improvements project, keeping everything on track to ensure the project was completed on time and within budget,” stated a news release from LOTT.

PSE’s conservation grant offers incentives and engineering consultation for industrial projects not covered by regular commercial programs. LOTT’s project resulted in an estimated energy savings of 2,458,000 kilowatt-hours per year. This is equivalent to a carbon offset of 1,143 tons and results in an annual energy cost savings of $180,899. Thanks to the PSE incentive grant, the equipment payback period is only 13.5 years, making these investments in energy conservation more cost-effective.

Since 1994, LOTT has employed biological nutrient removal as an added step to wastewater treatment, providing the highest level of treatment in the Puget Sound region. The Biological Process Improvements project, completed in 2023, reconfigured and consolidated the nutrient removal process, enhanced monitoring and controls, and replaced aging equipment with state-of-the-art technologies. The upgrades included energy-saving technologies and operational strategies estimated to significantly reduce overall plant electrical usage.
