In the ongoing battle to control odor, the Valley Forge Sewer Authority has yielded to local pressure and agreed to ship more sludge to landfills.
"The more you have, the more likely it is to produce odors," said Joseph S. Bateman, general manager of the sewage treatment facility in Schuylkill Township.
The sewage treatment plant, which serves eight Main Line municipalities, is expected to produce about 11,300 tons of sludge this year, Bateman said. Of that, about 2,100 tons of the claylike residue was scheduled to go to a landfill. The rest is used as fertilizer by local farmers.
