SEATTLE — The Lakehaven Utility District recently completed upgrades at its Lakota Wastewater Treatment Plant with improvements generating more than $850,000 in energy and operational savings, according to a press release.

The project, which included $250,000 in annual operational revenue along with a one-time revenue grant of $602,000, delivered a positive cash flow return to the district in less than one year, reported the release.

The Trane Energy Services group provided performance contracting and project management for the upgrade project and joined the utility district and the Department of Energy Services in hosting a ribbon cutting ceremony for the upgraded plant on Tuesday, May 20 at the Lakota Wastewater Treatment Plant, the release noted.

The utility, located in the south Sound region of Washington serves Federal Way, Des Moines and adjacent service areas, continued the release, and the improvements there were funded with a performance contract that allowed the district to use future energy and operational savings to finance infrastructure improvements up front.

"We’re pleased that we were able to fund critical improvements through energy and operational savings," said Christ McCalib, wastewater operational manager for Lakehaven Utility District. “We’re also pleased that we could complete the project in less than a year and delighted that we can realize a return on our investment early on.”
