OWTS Tank Repair Q&A#2

Question: Are the tanks completely empty?

Answer: No. There are still some liquid in the tanks. The tanks will be pump down to low suction (with approximately <500 gallon left) prior to handing them over to contractor for repair.

Question: Are there photos of the corroded tank bottoms?

Answer: No. There is no actual photo of the corroded tank bottoms of tanks 4C and 4D. The supplied photos (from tank 6A) are very similar to the condition of tank 4C and 4D.
