Link to First Five Years of "Dora's Page", 2019-2024
The City is pulling together its much-awaited explanation for Why It Happened, and, if possible, Who Lost The Watermain, for public-lynching purposes. My own trip to the gallows is unlikely: my involvement in large-mains inspection dropped rapidly after about 2007, and all three pictures today are from an excellent presentation on it given in 2009 by somebody else - great work I remained unaware of right through retirement. Still, it uses some maps I set up for the staff that were rapidly moving, at the time, from "Engineer in Training", to "top professionals". I only got this call because they are all too busy right now to help explain their ancient history.
2009 is fifteen years ago!?! And even then, we had surveyed the whole city for the kind of soils - that "toxic waste in your garden" I ranted about in the paper - that eat watermains. Great slide showing how the soil map made generations back by the Alberta Research Council was used to find soil-testing locations.
The dark brown polygon is from the Alberta Research Council; the light-brown buffer (I used "buff" as the colour, obviously) around it is created by computer. Everything within 100 metres of the suspect soil was tested, pipe looked at.
There were, and are, very few programs on the continent to compare to it; that it failed anyway is going to be quite a story.
