In one of its shortest meetings on record, the Town Center Sewer Committee met for barely 15 minutes Wednesday to pronounce that the project is still on schedule.

Work on all streets east of the Common is done, and the trenches have been capped with a layer of asphalt. No further work will be done on town center roads until spring, when mains will be installed on Ayer Road, Elm Street, and other roads on the west side of the sewer district.

This month, Ricciardi Bros. construction crews will begin work on the Massachusetts Avenue treatment plant that will handle wastewater from the new system. A Ricciardi spokesman said Wednesday that the company will use the month of January to install the underground tanks at the heart of the system.

Meanwhile, Kyle Hedrick, Sewer Commission liaison to the building committee, told the Press Wednesday that his three-member board expects to have draft sewer district policies and procedures ready for review by the Selectmen within the next few weeks.
