Wastewater Energy Coaching takes a deep dive into reducing energy use for wastewater treatment and collection systems.The two-year program helps participants reduce energy use through low- and no-cost operations and maintenance (O&M) adjustments and chart a course for long-term sustained savings by creating and implementing an energy management system.
A final workshop for the Washington Tri-Cities (mid-Columbia) Wastewater Energy Coaching cohort was held at Benton PUD in early March. This cohort has been working together for two years. Traditionally, the final workshop is all about participants sharing their stories of successes and challenges. A common theme among all the participating sites was the considerable savings achieved resulting from monitoring dissolved oxygen levels and cutting back on aeration.
One small site saved 50% of their energy use compared to their baseline–and, a large part of their savings won’t even kick in until summer. Another site is saving over 25% as a result of their strong commitment to becoming better at managing energy.
The workshop ended on a high note with congratulations and cake for all. In the words of the workshop’s coach, “it was a real Poopalooza!”
