In-ground pool drain for months, Summer, No Equipment Running

Haven't had to deal with and endless summer, extended drain before:

Client plans to demolish pool equipment room, build out their house with an extra rooms and is requesting to drain the in-ground, concrete with plaster, saltwater pool / spa.

Build could take many, many months. In Hawaii and not worried about severely heavy storms, but... heat heat heat.

Not sure yet exactly if we have a choice in the draining or not per their plans - but we all agree draining it for months would be way too risky in this heat, yes?

I've seen a crack happen in plaster in less than 18 hours when it was drained, so I should be hoping to leave it full of water, cover, treat / SLAM, add water as needed weekly for evap, brush / stir ? Any other summer / no equipment tips?

If forced to drain it, the only choice is to cover the plaster from debris stains ... and just hope for the best?

Thanks for thoughts / helpful links for reading!

Any concern of the pool popping out of ground with no water for extended time? If you can keep it full, you can cover and add chemicals, consider a submersible pump. Put it in the deep end and run the exit hose to the shallow end. run the pump 8 hrs or so a day to circulate water.

Thank you for the subpump idea. I knew there was something simple I wasn’t thinking about! Had been debating rigging up a pump with filter…

The pool is at an extremely dry area with porous and well draining lava rock, and some combo of fill in the yard. The only reason there is any green in the area is because of constant sprinklers running water.

Can’t say with 100% confidence there’s no concern of pop but in these conditions it’s probably not the most likely??

Thanks again for your reply.

Does the downtime stretch into monsoon season ? Even if the area can drain great, it can always be overwhelmed in a big storm as that water finds its way deep. And then you’ll have a boat instead of a pool.

There is a chance this could take a really long time so I’ll assume it can be into the rainy season. even at it’s worse down there I’ve hardly seen any drastic rain but again it could happen. Going to make everyone well aware of the risks of draining. Thanks for posting.
