Anaerobic Digester Dome Removal

Biological treatment of wastewater is an amazing thing.  One small portion in some facilities is taking solids, digesting them, capturing the gas they produce and then dewatering those solids.  That gas can be corrosive and eat away metal so the domes need to be replaced.  This was the removal of an old digester lid.  The weight of this guy was around 40,000 lbs and is 100' dia.
