Review of Trail/Sewer line bids continued.
1.
Chairman Lynch attended a preconstruction meeting and reported that tree cutting on the
trail/sewer will start on March 1. Construction on the sewer line will start April 1. Ms. Wadecki
asked which kind of pipe they would be installing. Chairman Lynch answered that the 5” PVC
pipes which the WPCA requested in the bid package. Mr. Juber said the project of putting in a
pump station where the line terminates could probably be put in as a change order. Chairman
Lynch agreed. Regarding Phase III, Weston & Sampson wants to put an odor control system in
the existing pump station. Chairman Lynch said the Authority needs to decide if the unused
pumps should be pulled out and sold or left alone since they are not in the way of the potential
odor control system. The Commissioners agreed that the pumps should be sold.
The sewer line construction around Ledyard High School will not start until school is out for the
summer.

RESULT:
Holmberg Tank Reservoir 2024 Inspection Report.
The Cortech analysis has been completed. There were several recommendations.
There was a question on piping. It read “a combination inlet and outlet pipe tree runs
horizontally across the floor of the tank. The tank fills through rubber duck bills and drains
through lower valves. Due to the use of stainless-steel screens over the outlet valves galvanic
corrosion can be observed forming along the length of the piping”. The evaluation doesn’t state
what to use in place of stainless steel. Chairman Lynch will ask Mauricio Duarte, GU General
Foreman Water Operations for clarification.
ACTION ITEM: Find out what material should be used in place of stainless steel for the screens
over the outlet valves.
ACTION ITEM: Get estimates from Groton Utilities on the cost of implementing the
recommendations in the Cortech analysis.
