Oh Black Water...

We recently endured storms that knocked out power in the Dunwoody area. One of these killed power to the nearby water treatment plant and before the generators could kick in the water pressure dropped to a level requiring boil-water advisories. While these were county-wide, the advisory lasted a day or two longer in DaVille. Watching those pots and boiling that water offered time for reflection, to ponder a few things.

First is the extremely long, automated call from the Dunwoody Police Department. How the hell did they get our phone numbers as we didn't offer them up and who the hell are they to make unsolicited calls? If someone wants alerts and calls let them register for them and leave everyone else alone. This should be exclusively opt-in and it isn't even opt-out as the City provides no [online] way to do so.

A bigger ponderance are those big blue structures around DaVille. You know that tall thing around the First Baptist Bank at Mt. Vernon and Ashford Dunwoody and the squat beast over by the Fire Station. The first is a water tower and the second is a ground based tank. Both store water. Potable water. To drink.

Where does this water (in these tanks) come from and where does it go? Well it seems to come from the water treatment plant, the very same one that lost power then water pressure and delivered questionable, perhaps non-potable water.


If DeKalb's system works like most, and given how screwed up this county is there is no guarantee, then the water from the treatment plant is pumped into the storage tank and tower and from there it is delivered to homes in the community. This raises all kinds of questions.

If the water supplied to the tower is tainted does this taint the entire tank? How much, in days of usage, does the tower hold? How does this impact (or even relate to) the number of days for a boiled water advisory? If the tank holds several days of supply how long does it take for tank water to go from potable to grey? Is there enough thru-flow to prevent degradation?

And finally, is the boil-water advisory just a CYA/PR stunt?
