Late to the party here, but the postponement at the weekend is entirely due to Dundee being manky as f**k and not solely a Dundee FC issue.
Having worked in the water industry, and on projects in Dundee specifically, that whole area of Dundee still has a Victorian pipe network clogged full of shit and I'm certain that's why nothing's draining away considering the long term weather.
To paint a picture, below is the sort of stuff we were dealing with on all the streets off Clepington Rd, and Dundonians are drinking and washing out of this . So aye, we should go easy on the dees for the drainage.
And for the lack of soap, really wouldn't make a difference.
