Outta' Water: Update #5 - amended

(Oops! A little bit of funky math and poor writing in the original post) Quick comment on progress, such as it is.  The city was able to hook us up to the fire hydrant below 12 tee.  Water will cost $1.18/1000L and we are going to need close to 4 000 000 litres (close to a million gallons).  River wise we did a dry run to test the plug and it worked.  Now we need to get a vacuum truck back in and clean out the interior wet well.  There is easily 2 feet of  sand and silt that is covering the bottom screens and bottom bowls on the pumps as well as the conduit that connects the two wet wells.  I felt around and the screens are clogged with debris.  We'll need to, obviously, clean screens and run the pumps to see if we have problems since pump #2 would not draw any water at one point during excavation of the infiltration gallery.  I guess worst case the shaft is broken somewhere along the column or best case the screen was just to plugged.  I am hoping for the latter.  At present, we are at the mercy of the vacuum truck availability which is suppose to be tomorrow (Thursday).  As always I'll keep you posted.
