Costs to build Portland drinking water reservoir soar past expectations

The price to construct a new drinking water reservoir in Southwest Portland has ballooned more than 200% over the project’s lifetime, according to officials’ recent testimony to the City Council.

New expenses were added Wednesday when the mayor and commissioners approved $8 million in spending increases that officials said were necessary to keep the project going.

All told, the cost to build a 12.4 million gallon underground reservoir at Washington Park in order to satisfy federal regulations has soared far past officials’ original estimate of $67 million when the project launched in 2009.
