Who determined that AT systems were an alternative to sewers?
A decision was made in the late 90s by the WPCA, in communication with the Selectmen, to pursue a non-sewer approach. The mediation served to develop the decentralized program further, to the extent that it was (reasonably) clear what would have to be done under this type of program for the DEP to be able to approve it. WPCA compared alternatives including conventional, ATS, community and centralized treatment options. Individual on-site solutions (including ATS where appropriate) were determined to be the best approach. The mediation primarily gathered together the parties to arrive at an agreement on technical standards, along with developing a program outline for the Upgrade program and AT Systems.
