Water contamination in diesel - EFRT

[dkf]

We have some diesel EFRT.
Tropical storms increased precipitation peaks, and this results in water intake via emergency drains. This increases water dispersion in product, as it flows through the product in its way to the bottom layer.
Water level is then measured and purged according to procedures.
I imagine that other sites face similar conditions.
In order to avoid contamination we came up with the idea to
install flexible hoses that convey water directly to bottom layer, hoping this will reduce contamination.
Does this make sense?
Hoses can be installed directly via drain intakes.
The hoses will reduce emergency drain capacity a bit, we do not think it relevant.
I would appreciate comments.
TIA

Why don't you install the flexible hoses directly to a spare nozzle on the shell and remove the water directly from the emergency drains, bypassing the contact with the diesel fuel? It will be cleaner than the water decanted from the tank.

gr2vessels, tanks are still in operation, and will remain so for the next couple of years.
We are looking for a solution that could be used right away.
And just inserting a hose through the emergency drain intakes would do it.
Question is, did anyone do it before? What was impact in water contaminating the product with the hoses in place?
Thank you for caring.
