Concrete Tank Leak Test
Concrete Tank Leak Test
(OP)
Hi,
Does anyone know what the allowable leakage is for a concrete tank. Some say its 0.5%. Is this correct?
We just put a 150k gallon up and is ready for commision, but we need to verify that the leak test passed.
Please advise.
Thanks

The test shall consist of measuring the liquid level over the next 24 hours to determine if any change has occurred. If a change is observed and exceeds the maximum allowance, the test shall be extended to a total of five days. If at the end of five days the average daily change has not exceeded the maximum allowance, the test shall be considered satisfactory.
B. The liquid volume loss for a period of 24 hours shall not exceed one-twentieth of one percent of the tank capacity, 0.0005 x tank volume. If the liquid volume
loss exceeds this amount, it shall be considered excessive, and the tank shall be repaired and retested.
C. Damp spots will not be permitted at any location on the tank wall. Damp spots are defined as spots where moisture can be picked up on a dry hand. All such areas shall be repaired as necessary.
D. Damp spots or standing water on the footing may occur upon tank filling and are permissible within the allowable volume loss. Measurable flow in this area is not permissible and must be corrected.
