Z-forms, flow throughs, and other tools of the trade

(btw that little yellow thing is our multi gas monitor "sniffer" making certain no toxic waste is in the air...)

Twice our z-form shields collapsed. We had a ten foot unshielded dig under a steam tunnel, and a typically dry sewer line decided to rage during our replacement of the existing pipe creating a three foot deep soup of caca straight from the chemistry building. S*&! happens. When you're tying in to an existing sewer line, however, it may happen in the form of a river. And when it happens behind the UVa Chem building, you just hope that the undergrads remember to put their hazardous waste in the proper disposal bin... So fierce the raging river that our three inch pump made not a dent, and a four inch diesel line was required... All in a days work. We gotter' done and got outta there before four PM.

Well at least the 4" Godwin pump (see bottom right) is working and the sewage swamp is low enough to walk around safely.

Setting the pipe - Dan you are the man for getting under that steam tunnel - yes we use chemical detectors aka sniffers... yet it stinks, especially the pipe glues for PVC.

Whattup Harley - we got real flow :)
