π Road work ahead π Ya, I sure hope it does π
You might see some work going on in town and think to yourself "What are they doing down the manholes? We are working through our sewer main lining program right now!
Crews will first send a camera into the pipe to inspect the condition and find issues like cracks. We fix the pipes by using what is called in-situ pipe lining which works like a "pipe within a pipe". A flexible liner is saturated with a liquid resin, such as epoxy or polyester. This liner is pulled or inverted into the existing pipe through an access point, such as a manhole and then is inflated and cured creating the "new pipe".
You can learn more about main lining in edition 4.6 of the DPW Discussion newsletter: https://www.salinemi.gov/departments/public_works/index.php
