There is no recession in the waste business.
The Twin Cities' treatment facility is buzzing with activity, and for good reason. "We take in raw sewage and return 11 millions gallons of clean water per day into the Androscoggin River. The water . . . is cleaner than the water flowing in the river," says Mac Richardson, superintendent of the Lewiston-Auburn Water Pollution Control Authority.
The plant, located on Lincoln Street in Lewiston, also generates tons of treated nutrient-rich bio-solids, which is made available to farmers for use as soil enrichment. The plant also produces tons of compost, which is sold to commercial enterprises and the public.
A $15 million project is currently under way at the site. An anaerobic digester is being constructed that will harness methane gas produced by the treatment process and convert it to electricity. The power will help run the facility and save an estimated $20,000 a month.
