UNION CITY — The Tri-City group that treats wastewater and sewage says it will save energy and income from a new trickery that reuses gas to power partial of a Union City plant.
The Union Sanitary District’s “cogeneration facility” translates a biogas that it generates into electrical power during a Benson Road property, that could revoke a agency’s power bills by tens of millions of dollars over a new building’s life span.
“Everybody wants to save on energy costs while regulating materials that would differently be wasted, and this will assistance us grasp that” pronounced district house President Manny Fernandez. “It’s a good idea, formulating energy out of something you’d routinely dispose of.”
The Union Sanitary District treats millions of gallons of wastewater and offers collection and ordering services to residents and businesses in Fremont, Newark and Union City. Its sum annual check this year is around $56.7 million, district General Manager Paul Eldredge said.
The $14.5 million cogeneration trickery took dual years to build during a district’s 33-acre plant on a western corner of town. Last month, a group distinguished a opening of a 30-foot-tall, 5,000-square-foot steel building. The cogeneration trickery was partly saved by a scarcely $3.4 million extend from PGE, Eldredge said.
The special district for decades has used methane gas combined from treating and violation down sewage and wastewater. That gas afterwards has been reused as energy to power a agency’s cogeneration engines.
The aged engines, in use for about 30 years, were transposed recently by bigger ones that are some-more fit and can repurpose a larger turn of methane gas, district leaders said. The new engines, approaching to final about 20 years, are means to use all of a gas constructed by a plant’s diagnosis system, since a aged ones could usually modify about 50 percent of it, Eldredge said.
“Wastewater diagnosis is an energy-intensive process, and we’re always looking for ways to revoke a operational expenses,” he said, “The volume of power that we beget (with a new engines) will isolate us and ratepayers from rising power costs.”
The upgraded apparatus has warranted a approval of Rep. Eric Swalwell, D-Dublin, who final month gave Union Sanitary District a special congressional certificate. He lauded a group for a “commitment and loyalty to renewable energy.”
If a trickery works as it should, group leaders said, a district competence revoke a annual $2 million energy costs by some-more than 75 percent, holding a yearly check reduce than $500,000.
“This is one of many USD projects that assistance us … make a best use of a public’s assets,” Eldredge said.
