Lakehaven Utility District Completes Improvements, Generating

More than $850,000 in Savings

Trane to participate in joint ribbon cutting ceremony to celebrate savings

Seattle, Wash., May 19, 2014 – 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. 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.

The Trane Energy Services group provided performance contracting and project management for the upgrade project and will join the utility district and the Department of Energy Services in hosting a ribbon cutting ceremony for the upgraded plant on Tuesday, May 20 at 3:30 p.m. at the Lakota Wastewater Treatment Plant, 3203 Southwest-Point Road, Federal Way, Wash., 98203. The utility, located in the south Sound region of Washington serves Federal Way, Des Moines, and adjacent service areas.  Trane is a leading global provider of indoor comfort solutions and services and a brand of Ingersoll Rand.

The improvements at Lakota Wastewater Treatment Plant were funded with a performance contract that allowed the district to use future energy and operational savings to finance infrastructure improvements up front.

Performance contracting is a funding option that provides measurable organizational results to support strategic objectives. The completed upgrades improve current process instability issues, reduce operations and maintenance costs, reduce power consumption, and offset capital repairs by three times as long as current conventional technology. They also allow for future biological nutrient removal air demand to be met for future nitrogen control.

“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.”

Prior to implementing the improvements, the plant also depended upon outdated infrastructure systems which doubled the use of required horsepower in aeration equipment. These outdated systems made the plant reliant upon $500,000 in chemical-aided treatment to comply with National Pollutant Discharge Elimination System permit limits. 

The utility district selected Trane as its energy services company partner to manage the entire process plant updating process, allowing the district to make the best use of its limited staff and resources. Aware of the risks of potential plant failure while still facing fiscal challenges, McCalib accessed a performance contract through Trane and the State of Washington Design/Build Energy Savings Performance Contracting Program (ESPC), authorized under state law and managed by the State Department of Enterprise Services. 

Through the ESPC Program, the district was able to fund the complete replacement and optimization of its secondary treatment system aeration at one time – rather than over several years – greatly reducing the risk of failure and compliance violations.
