The first project is the Pine Water Treatment Plant Improvements.  This project will double the city’s capacity of water.  The complete final plans should be ready by the end of February with advertising for bids the end of March and the opening of bids the end of April.  Construction could begin in early June with construction expected to take 10 to 12 months.  Total estimated project cost, $1,873,000.

The Ledyard Water Treatment media replacement project is ready for bid.  The project was moved up because of the number of brown water complaints being received.  The media replacement will make a significant change in the clarity of the water although it was noted that the issues have only be a nuisance and not a quality problem.  Bids are expected to be opened on February 13th with construction to being in early March.  Estimated project cost is $189,300.

The final project is the Wastewater CSO – headwork’s influent controls. The project will update the automation controls making control in the plant more efficient during a rain event.  They will also replace some existing controls also.   The design should be complete in mid February with advertising for bids in March, bid opening in April and construction to begin in May.  Estimated project cost is $134,600.
