Case Study: Lakehaven Utility District achieves $850K in savings with Trane Commercial HVAC

Lakota Wastewater Treatment Plant

Lakehaven Utility District faced the challenge of upgrading the aging infrastructure at its Lakota Wastewater Treatment Plant. The outdated systems were inefficient, requiring excessive horsepower for aeration and reliance on chemicals to meet compliance standards, all while risking potential plant failure. They partnered with Trane Commercial to address these critical issues through an Energy Savings Performance Contracting (ESPC) program.

Trane implemented a comprehensive upgrade of the plant's secondary treatment aeration system, financed through the Washington ESPC program. This solution allowed the district to use future savings for upfront improvements. The project achieved $850,000 in energy and operational savings for Lakehaven Utility District, including a 30% reduction in chemical costs, and delivered a positive cash flow in less than one year.
