Digester gas irom anaerobic digester is stored in 35-foot high, 25-foot diameter gas tank.
The anaerobic digester, gas tank and related facilities were constructed in 2000. The gas

with an inner flexible diaphragm where the gas is stored. Both external and internal sides
of the structure have rust and coating delamination which needs to be renovated to
maintain the integrity of the structure.
This project was out to bid in July, and 4 contractors came to a prebid meeting on July

be well qualified for this work.
