Old water storage tanks to be removed from Forest Park
On Monday, August 29, 2011, a contractor for the Portland Water Bureau (PWB) will start the removal of the two old water storage tanks located inside the boundaries of Forest Park, near 11159 NW 2nd Street in Northwest Portland. The work is to be completed before September 30. Recently, the contractor completed the upgrade of the PWB's Linnton drinking water pump station, adjacent to the tanks.
The contractor will demolish the 1913-built tanks (Old Whitwood Tank and Upper Linnton Tank) that were leaking and taken out of services many years ago. The steel and other materials will be recycled.
The Linnton pump station remodel project was to address customer complaints about low water pressure in the area. The work involved the removal of the existing pumping system and piping inside the facility. The contractor retro-fit the existing building with new pumps and piping that will improve water service. Fire flow capacity also will be increased from its previous flow of around 1,300 gallon per minute (gpm) to 1,800 gpm. The Portland Fire Bureau requires 1,750 gpm for fire flow in this area because it is an Urban-Wildland interface zone. The Linnton Pump Station improvements meet all of the fire flow requirements.
During the tank demolition work, there may be some minor inconvenience to adjacent residents with construction noise, dust and truck use of the street. The contractor’s vehicles will not block the roadway. Every effort will be made to accommodate residents’ needs during this work.
No official Forest Park hiking trails will be closed as part of this work. The tanks are located up an old road grade that is not an official Portland Parks & Recreation maintained trail open to the public. The contractor will use the official Leif Erickson Trail to access the demolition site. Workers serving as spotters will alert trail users if equipment or vehicles are being moved. Park trail users are asked to please obey the spotter's instructions.
