Problems with drainage ditches in the tank farm
Thread Content
I have a question: In a tank farm where there are two types of oils stored within the fire dike, and a partition dike is installed there according to the design specifications, can the drainage water within the fire dike pass through this partition dike?
If the function of the dike is taken into account, then it should not be possible.
If a dike is installed in the middle of the oil tank in accordance with design specifications, the drainage ditches within the fire dike must not pass through that dike. In the case of individual oil tank areas, just as in your example, after examining the drawings and the site, I found that the drainage ditches within the fire dike do not pass through the dike.
It is best to replace the drainage ditches with drainage pipes, which should be coated to prevent corrosion and then buried underground! Install an oil-water separation tank outside the cofferdam to meet the standards!
Separate rainwater ditches should be installed for this purpose. In the project I am working on, after assigning the task of installing rainwater ditches to the plumbing and drainage specialists, that’s exactly how they carried out the installation.
Drainage ditches must not pass through the dike; separate drainage ditches and water seal wells should be installed.
No, a water seal well needs to be installed. What’s the use of a fire dike if it has holes in it?
