Lightning protection of steel water tank

[MikiBg]

Hi all.
Steel tank for potable water is on the top of steel supporting structure. Early streamer emission device is planned to be installed on the top of it, in order to protect other facilities. Steel supporting structure can be used as natural down conductor. My question is should I use non insulated or insulated protection system, since steel structure as well as tank itself is directly connected to well pumps via steel pipes and water. Is there a potential danger to water users or pumps during lightning discharge?
On the other hand, even if I use a insulated system (which will be far more difficult to install because it will require insulated distance holders) earth termination electrode will still be in touch with pipes and water via surrounding soil and steel structure.
Hope that someone can give me an advice what is a good solution in this case.

Sounds more like a Civil engineering question...

Suggest You place this question on the "Civil/Environmental Engineering Other Topics" forum.
