Inverness Force Main Construction Update: April 20, 2017

Inverness Force Main Construction Update: April 20, 2017

Bike/Pedestrian bridge closure extended to May 15

The Inverness Force Main is an 11-mile pressure sewer that carries sewage from northeast Portland to the Columbia Boulevard Wastewater Treatment Plan. The 36-inch line splits into a 20-inch and a 30-inch pipe about two miles east of the plant. Both sections are suspended underneath the Columbia Slough Pedestrian Trail Bridge, which Environmental Services constructed. When maintenance crews found the leak in the 30-inch pipe two years ago, all flow switched to the 20-inch pipe and plans for repairs began.

DEVELOPMENTS OF NOTE

  • The Columbia Slough Bike/Pedestrian Trail Bridge will be closed two weeks longer than originally anticipated due to delay in arrival of a critical component to complete the work. Once the repair work is complete, the excavations on each end of the bridge will be restored and the bike and pedestrian bridge will reopen.
  • There will be a period of inactivity for up to a month while another piece of specialized equipment arrives from overseas in mid-June. This final piece will take several days to install and will not require the bridge to be closed.
  • The Inverness Force Mains will both be operational by the end of June.
