Yeah, but a ship is small. The expensive piping systems are acceptable. Same as we do it offshore. The pressures are low because you are not piping it up a mountain, nor for miles and miles. I’m not familiar with ships, but offshore they can have dry systems that only fill up in case of a fire. Not possible in this case because it would take too long to fill the system. Maybe you could fill it with freshwater and come behind with saltwater in the event of a fire. Still, it would only be useful very near the coast and would require a lot of infrastructure.

If that was all we had we could figure out a way, but we can use freshwater trapped in reservoirs. So easy.

Show me the evidence that this chemical danger even exists.

Your local chemistry teacher is closer to you than I.

It would take 1200 PSI to pump water to the top of the Santa Monica Mountains, and that’s just to overcome the head; you haven’t moved it a foot yet.

I understand that, but they could figure something out. Build reservoirs in stages up the hills and leave it filled with salt, shite water, whatever. It doesn't matter if it's last resort.

How do they fill the Santa Ynez Reservoir ?

Salt water might have save Malibu though.

last resort

Why? It should be used immediately when problems arise

The fact that there is a chemical reaction, doesn't mean that exact chemical reaction happens in firefighting , or that it happens enough to be a problem.

I have just referenced about 20 articles concerning the use of seawater in firefighting. They all mention the corrosive nature of the water and the environmental issues with saltwater, but never a mention of this hydrogen chloride gas problem you speak so fondly of.

If you’re building reservoirs fill them with freshwater and come water. There is plenty of it.

Just use the salt water as a last resort. Better than nothing.

that's my view - could never understand why they didn't have that capacity.
can always replant the vegetation - even remove the salted soil and replace with good topsoil for far less than the cost of total rebuild.

They have apparently gotten over their issues with using sea water.

When i started this thread i never thought it would go in such diverse directions. Hey you have a fire. You need water. Ocean water, while salty is till 96%+ water. The “salts’” in the water are corrosive but given the situation you build a system that can handle the salt and especially if you are close to the ocean you spray this water, as is, on your house. Everybody within a new blocks of the oceans does this let’s say. Hey if it’s my $5M house that’s something I’d do.

The problem is a lack of any common sense. There are way too many people even in this thread way over thinking this situation.

Ever cook crawfish in your backyard and dump the water in your grass? Does it kill the grass? Yes. Does the grass grow back after a few weeks? Yes. Salt water isn’t gong to ruin the soil used in emergencies. . It will save your house though if it’s on fire.

Anybody ever get hydrogen chloride “gassed” cooking crawfish? That’s some total BS there. I can tell you there is a higher concentration of salt in that crawfish pot than in the Pacific Ocean.

Now i can understand it may not be feasible to pump that ocean water to a 2500 foot elevation. A reasonable elevation, say a 300 foot elevation should be easily doable. All plastic piping would work and the pressure would be around 150 psi. I can’t get my mind off seeing $5M houses burned down while sitting on an ocean.

Pretty sure near the coast over the eons tidal waves have washed miles inland and things still grow, I don't think a little salt water on some houses and yards is going to hurt anything.
