Public works and the eagle next door

Victoria has been criticized for years for not having sewage treatment facilities.  There is primary treatment (screening) but essentially we were spewing raw sewage into the Strait of Juan de Fuca.  Only recently has Victoria been mandated to build a treatment system.  Part of this system will entail pumping sewage from one part of town to another, under the harbour to another treatment facility.  (More info: http://www.timescolonist.com/islander/all-about-the-sewage-pipe-that-will-run-under-victoria-harbour-1.23205174)  So they built a pipeline that is:  "1.1 metres in diameter and 940 metres long, made up of 78 sections, each 12.2 metres in length. It is made of steel with a polyurethane liner. It has a combined weight of 615,300 kilograms."


 You can see the rollers the pipe passes over


Then, over the period of about three days, they drag this pipe through a tunnel that had been drilled under the harbour.

 Watch the pipe move!

Quite the engineering accomplishment.  The project took a long time to complete and the pipe created a barrier through the neighbourhood for many weeks.  



Fortunately I was in Mexico for most of it but was glad to get in on this last stage.

 The last bit gets rammed into the tunnel.

And then, one day, for something completely different, there was the eagle on the roof next door
