The ever-increasing pressure on wastewater treatment plants (WWTP) to sustainably improve operations while controlling costs, requires operators to investigate technological improvements and innovative design to update facilities and operations. Harnessing the latest innovations and best available technology to meet specific needs often requires long term planning, difficult investment decisions and increased exposure to various forms of risk. This elevated risk has local governments, utilities, and WWTPs looking for alternative contracting methods to achieve their goals while controlling exposure to risk.
This session will compare the risk, and associated issues, across a spectrum of alternative contracting pathways, including Energy Savings Performance Contracting (ESPC). ESPC is a project development pathway that guarantees the resource and energy savings; project performance; and maximum costs for implementation. The Energy Services Company (ESCO) carries the risk of the project outcome, mitigating risk to the plant Owner. While the ESPC/ESCO pathway in enabled across the country, contracting requirements differ from state to state. This proven implementation method is prescribed through legislation and offers financing structures not available through other alternative contracting methods.
The project team will discuss why the City of Edmonds selected performance contracting to complete three phases of plant upgrades, bridging the gap between risk and effective energy-centric project delivery. The session will be hosted by Edmonds WWTP Manager, Pamela Randolph; Wastewater Engineer with BHC Consultants, Greg Mockos; Department of Enterprise Services, Project Manager, Butch Boles; and Ameresco Account Executive, Murray Greenwood. With a clear explanation of the ESPC pathway, the project team will discuss their perspective on the challenges faced; the collaborative solutions developed; and the project outcomes the team was able to achieve in Edmonds.

Pathway to Sustainability – Performance Contracting and Collaborative Problem-Solving Leads to Innovative Resource Recovery

In the first session, the project team discussed risk factors across a range of alternate contracting vehicles and explained why the ESPC approach was the best pathway for the City of Edmonds. In this session, we will delve into these energy efficiency case studies, focusing on the challenges that arose and how the ESPC approach enabled collaborative solutions to be developed. We will also look at the project outcomes, and how these projects established Edmonds’ Pathway to Sustainability.
Before setting out on a Pathway to Sustainability, this team created a long-term vision, and established a phased strategy for plant improvements. The phases focused on treatment plant processes with aged or inefficient equipment needing replacement. The goal was to achieve incremental improvements that would eventually enable the City to either replace the Sanitary Sewage Sludge Incinerator or find an alternative method of treatment that recovers energy.
The panel will share the goals, challenges and accomplishments of three completed ESPC projects and discuss how the projects paved the way for their future Resource Recovery project. We will share the savings achieved to date and future savings anticipated with the completion of our innovative Carbon Recovery project. This will be the first in the Northwest wastewater treatment industry to implement pyrolysis technology for the processing of wastewater biosolids.
