State hopes to boost energy efficiency at water, sewage treatment plants
By Globe Staff
State officials today announced a pilot energy efficiency program for water and sewage treatment plants, saying that if communities cut energy use at their plants, they could save big money on their electric bills and help the environment at the same time.
Cities and towns statewide spend about $150 million per year for electricity in treating 662 billion gallons of wastewater and drinking water. Running the plants accounts for about 30 percent of municipal energy use, state officials said.
"This pilot project will help a first round of municipalities reduce their energy use and save money for their customers -- and lead the way for others to do the same," Energy and Environmental Affairs Secretary Ian Bowles said in a statement.
The goal is to cut 20 percent off that $150 million bill, said Energy and Environmental Affairs Secretary Ian Bowles, saving $30 million.
He said energy saving techniques could include installing new variable-speed pumps. The conservation measures could also include steps like those people might take in their own homes, such as installing new compact flourescent light bulbs.
The energy audits will also look into whether the plants could take advantage of renewable energy, such as wind, solar, or geothermal power, he said..
State officials said the $326,000 program will help 13 municipalities.
The state Department of Environmental Protection will lead a group of partners, including both public agencies and utilities, that will work together to audit the facilities; assess the potential for clean, renewable energy at them; and provide financial support for efficiency measures.
The communities or water districts to be included in the program are: Falmouth, Ashland, Easton, Lee, New Bedford, Townsend, Worcester, Barnstable Treatment Facility, Charles River Pollution Control District, Falmouth Treatment Facility, Lowell Regional Wastewater Utility, Pittsfield Treatment Facility, and the Upper Blackstone Wastewater Pollution Control District.
