The Deer Island plant is considered the centerpiece of MWRA’s $3.8bn program to protect Boston Harbor against pollution from Metropolitan Boston’s sewer systems.
SourceOne president Vincent Martin said the Deer Island wastewater treatment plant will identify and implement cost-effective solutions to drive efficiency and increase performance.
The energy-efficient infrastructure upgrades performed by SourceOne include a waste-to-energy boiler plant that uses methane from the wastewater treatment process to generate steam for space heating and treatment process requirements.
Also, one 18,000kW back pressure steam turbine generator, two 600kW and one 100kW wind turbine generators, two 1,000kW hydro turbine generators and about 700kW photovoltaic paneling on facility rooftops.
SourceOne worked with the MWRA to install a new 1.1 MW back pressure steam turbine generator.
The MWRA’s plant treats an average of 350 million gallons of wastewater each day from 43 communities in greater Boston and is one of the largest electricity users in the Northeast.
