Case Study: City of Bremerton achieves major energy savings and wastewater plant upgrades with Trane Commercial HVAC

City of Bremerton

The City of Bremerton faced a challenge with aging and unreliable equipment at its wastewater treatment plant, its highest energy user. The primary effluent pumping system was of particular concern, as a failure could cause a catastrophic environmental hazard. The city needed to replace the equipment in a timely manner without disrupting service and at a cost that fit its budget. Trane Commercial was engaged to provide a solution through its Energy Efficiency Contracting services.

Trane implemented an upgrade to the plant's pumping system using an Energy Savings Performance Contract, which simplified procurement and provided a single point of accountability. The solution included replacing pumps with state-of-the-art models featuring variable frequency drive controls. The project resulted in significant energy savings of over $167,000 and secured $913,000 in grants and incentives. The upgrades also reduced the risk of critical system failure and yielded annual maintenance savings of more than $30,000.
