Help us name our Tunnel Boring Machine (TBM)!

This summer the Ship Canal Water Quality Project’s Tunnel Boring Machine (TBM) will begin digging a 2.7-mile long, 18-ft 10-in diameter storage tunnel. Starting in 2025, this tunnel will keep more than 75 million gallons of sewage and polluted stormwater from entering our waters on average each year.

We know that this TBM is working for public health, a mechanical marvel, and an important part of our team. We just need a name.

We want you to #NameThatTBM. Submit TBM naming ideas by midnight on March 12, 2021 via Twitter (#NameThatTBM) or online

Some folks at Seattle Public Utilities have some Seattle-themed suggestions -watch their video here – but, well, they need some work.

Contest rules:

  • Submission must be original work by the entrant.
  • Group/organization submissions welcome!
  • Any entries using profanity or offensive language will be disqualified.
  • All entries may be listed on Seattle Public Utilities websites, print materials, and social media channels.

Project team members will select their favorite submissions and then put them to a public vote. Voting will take place between March 18 -24.

Submit your TBM name here!
