The announcement won't change the city's plans to take its reservoirs underground—complying with an EPA rule known as Long Term 2 Enhanced Surface Water Treatment Rule, or LT2. The Portland Water Bureau already has a $275 million reservoir replacement plan underway, as WW reported last summer.



One of the two Washington Park reservoirs will be buried and covered with a reflecting pool, and the city will drain its three Mount Tabor reservoirs and move eastside water storage to underground tanks at Kelly Butte and Powell Butte.



But documents reviewed by WW show the city has not created any plan for what to do with the Mount Tabor reservoirs after the Dec. 31, 2015 deadline, except that the city will disconnect and probably drain them.
