Need help finding information to size a water reservoir to supply fire protection of an oil tank farm (4 tanks (15 MM gals total)).
Each tank is approx. 190 ft. in diameter and 25 ft high.
If I specify that fill materials are to be compacted to 95% of the maximum dry density obtained by the Modified Proctor Test, ASTM D1557, how is this compaction verifed in the field as the work is progressing?
