The city plans to break ground in early May and will start taking bids from contractors Thursday.

That means the facility wil  be done by the end of 2015 or early 2016.

Project Manager Heidi Lansdowne says it will be more than a year late to meet the federal government's deadline to be treating the water for parasites like cyptosporidium.

"For a project this size and complexity, it's gonna take awhile to be completed.  It should be done by December 2015 or Janaury 2016.  It's a big building with technical equipment and piping.  It's a 30 million dollar project."

Lansdowne says  they are in contact with the Oregon Health Authority about the timeline.  The filtration plant is supposed to be operaitng by October 2014, but the OHS says contact them then and they'll discuss what the options are.
