BACKGROUND: On November 1, 2013, the Board of Public Utilities (Board) approved the rehabilitation project of five wells. The work for each well required removal of the existing pump and motor followed by performing a video survey of the existing conditions of the well screen. The well rehabilitation work for the Thorne 12 Well was completed in the fall of 2014. The Board authorized $176,000 for Work Order No. 1408503 of which about $50,000 remains. The pump and motor were inspected and determined to be in poor condition and need to be replaced, In addition, staff recommends that the new pump be placed deeper to account for lower water table levels in the Bunker Hill Basin. This work will be for the replacement of the pump and motor as well as for the increasing of the length of the pumping column. The refurbished well is expected to provide up to 2,000 gallons per minute to the potable water system.

In accordance with that contractor panel, staff solicited bids for equipping the well under bid number RPU-7304. Two bids were received on January 12, 2015.
