The Dalles City Council will consider adopting a draft drinking water system master plan at its meeting on Monday.  Topping the list of projects in need of immediate attention, replacement of the Wicks Water Treatment Plant, which is over 75 years old and past its useful life.  The Dalles Public Works Director Dave Anderson says the estimated cost to replace the plant is $88 million, but he says funds from new Google developments and the revenue the City receives from the water use will be a key part of paying for it.  Anderson said rate adjustments to municipal water customers would be a part of the funding plan, adding that rates have not been changed since December 2014.  The Council considers the master plan at its meeting starting at 6 p.m. Monday evening in The Dalles City Hall.
