GENERAL DISCUSSION ITEM
Subject:
title
Retirement of Chlorination Station on Route 12.
end
Background:
Inactivate the Booster Chlorination Treatment Plant -
Project description: The Gales Ferry Chemical Building is located on the Groton/Gales Ferry border between 1320 Route 12 (Groton) and 1434 Route 12 (Gales Ferry). Located within the structure there is a sodium hypochlorite treatment system for boosting chlorination. That system is completely mothballed and would need extensive rehabilitation if it was desired to put it back in service. Due to the nature of the distribution system, it would be undesirable to operate this treatment system, because it would increase the THM formation within the system, for this reason, we are applying to inactivate this treatment system for the LWPCA Gales Ferry Water

DPH and GU recommended inactivating the booster chlorination treatment system on Route 12; because it is no longer used or needed, and the WPCA agreed that it could be abandoned. It was originally used to sanitize water in the Route 12 main, but with the addition of the Holmberg tank and the regional interconnection crossing under the Thames River, there is enough water moving that it does not stagnate or require additional chlorine.
