Re: Opening after Katrina
Just my personal opinion on it, but what I'd do is scoop out as much of the solid debris and "critters" as you can. I also wouldn't filter the water just yet, I'd it on circulate instead. Then, after a few days and it looks like the algae is dead then I'd think about switching it to filter.
But, I've never cleaned up a "swamp". Best of luck!

What happened on August 29th?
Its rather a mess. I can see just far enough into the water to verify that there are tadpoles living in there, and there also must be leaves, debris, mud, and who knows what else. The pool is approximately 32 x 15 and has a deep end for the diving board, so I estimate the capacity at 22k gallons. It is equipped with a Tagelus sand filter supplied by a 1/2hp Triton pump, and a gas-fired heater (in New Orleans?).
I am the kind of person who likes to have a plan, which is why I am starting this so far in advance. I'd like to get the pool cleaned up fairly promptly if only to eliminate the odor, but I also have some constraints.
1. I don't see draining and re-filling as an option. The water table here is quite high, and I don't know what hydrostatic relief is available.
Is this a gunite or vinyl pool?
2. I will have only part-time generator power, at least for awhile. The house took 24" of water and the local utility (and good sense) dictates major work before permenant power can be restored. I don't know how quickly temporary construction power can be obtained.
The more you can filter, the better. You probably need 8-12 hours of pump time under normal conditions for that pool; you'll need to exceed that in this scenario.
So far, from my reading, I think that the plan is to have Grainger deliver a pallet of bleach, a new pump motor (it was underwater for a couple of weeks) and several hundred pounds of borax. I guess my biggest concerns are the need to break up the mass of algae so the chlorine can get at it effectively and how to vacuum out, or otherwise remove, debris that the pump/filter can't.
The bleach and pump motor are a good idea. Borax is used to raise the pH so unless you know that your pH is incredibly low, that much borax might be overkill.
I have seen a couple of sites (such as Steve Litts') about this kind of thing, but I would ask this group: Thoughts on cleaning up a swamp?
Dag,
Welcome to the forum. I'm a SE Louisiana resident too and there are a few others here too.
Your proactive approach is commendable and will certainly pay dividends.
I'd manually remove all of the junk in the pool that you possibly can with a leaf rake/hand skimmer. That will probably take many iterations as you'll be working blind.
You'll need to get your chlorine up to shock level (I'd shoot for 15-20 ppm since you almost certainly don't have any CYA in the pool) as soon as you can and bring the pH into the 7.2 to 7.8 range. It will take a bunch of chlorine to keep it at that level. The more often you can test and return the chlorine to that level the faster this will go; 3 times per day is probably the minimum that will get you good results. I wouldn't worry about any of the other chemistry numbers until you get the water cleared up.
Run the filter pump as much as you can. You'll probably have to backwash the filter quite often.
Keep manually removing everything you can throughout the process.
You'll almost certainly have significant staining that you may only be able to deal with by draining, but I think you can deal with that if/when you have to.
Good luck.
Kurt
Re: Opening after Katrina
August 29th 2005 is when Hurricane Katrina hit New Orleans and surrounding areas. So this pool was abandoned after that particular calamity.
Re: Opening after Katrina
Just a thought here...
maybe a vacuum that is "stand-alone" - has it's own filtering system might be also a really good idea
on top of regular vacuuming through the filter
also some type of skimming machine/product ( like a pool devil) could also be useful..
plus filter socks in your skimmer basket
The more filtering, the better
Good Luck & Congrats on your new home :)
Re: Opening after Katrina
I think if it were my pool in your situation, I would strongly consider changing out the sand in the filter once you get the pool cleaned up. Normally sand doesn't really need to be changed, but my personal experiences with the stuff that was in the floodwaters down there lead me to believe that you need to be rid of all of it to truly get your pool clean.
I agree with the others...rake out what you can, bleach it, maintaining 10-15 ppm all the time, and vaccuum and brush as the water clears so you can get to as much of the debris as possible. Use a drop-based test kit for testing, so you have accurate numbers to work with.
Good luck!!

cygnus,
My question was tongue in cheek; I'm from there too.

Sorry kurtv, I was wondering about that :-) I don't know enough of your posts to know when you're serious or not, without clues like winking smileys..
Re: Opening after Katrina
I figured that KurtV's question wasn't serious. Mandeville is close enough that the date is firmly fixed in everyone's mind. How many trees did you lose, Kurt? ;->
Thanks for the feed back. One suggestion that closely parellels my thinking is to set up filtration that is independent of the existing sand filter. Since that system is really a polishing filter, and not designed to take out large amounts of large things, I'd like to try to set up some coarser filtration.
I'm thinking about either a largish (4000 gph) bilge pump or a 2" gasoline powered rental pump feeding a temporary mesh, coarse sand, or even plate-and-frame filter. Anyone have any experience with, or heard of anyone using, something like that?
As for staining, the house sale disclosure said that the pool needed replastering, so I figure that it will get handled soon anyway. Oh, and I understand that the borax is to increase pH...I figured that by the time I had 50 or so cumulative gallons of bleach in the pool, I'd need some pH adjustment. I hadn't actually run the calculations to see how much would be needed, though.
Either way, when the time comes, if anyone's interested I can post progress reports.
Re: Opening after Katrina
I'll be looking for updates. I'm also really curious about what your beginning pH is....

cyg,
The same thing happens to me in person. Not only can't I write clearly, but my oral sarcasm is sometimes misinterpreted as well.:)
dag,
Since you're going to have to drain the pool to replaster anyway, I think you should consider just draining and replastering immediately. What's to be gained by cleaning up the water only to drain it for the replastering?
As aylad said, there'll be much interest in following your project.
I lost more trees than I cared to count (north of twenty) but none were on the house or in the pool.

Ah, excellent point that I hadn't seriously considered. I guess that the re-plaster guys might have a plan for how to avoid the "floated pool syndrome" and get all the debris out. Perhaps I should call someone and get an estimate and a plan.
Re: Opening after Katrina
Your biggest problem, No power! Until your able to get power to the pump, via shore power or a generator, the only thing you could start to do is remove the debris.
Even having it replastered.......your a step ahead, but back to the no power problem.
But, if you want to try the "trash pump & garbage cans homemade filter system", it can be done, but gets expensive gas wise. It will not make the pool perfect, but could make it clear enough for a quick swim. If you decide to go this route, your going to need 3 garbage cans, window screen, pea gravel, filter sand( I used play sand), pvc,vinyl tubing, pvc cement, clamps and some imagination to rig up your filter. After, Hurricane Frances in 04, after the 3rd day without power, I rigged up my homemade system it wasn't pretty and the pool wasn't crystal clear, but good enough for a swim. By the 14th day power was back on....until Hurricane Jeanne knock us out for 9 days.
But I'll go step by step on what I did to rig it up.
Re: Opening after Katrina
After review, we've decided that Kurt is correct, and we are getting replastering quotes this week (closed on the new house Monday). As expected, the pump motor is siezed and a new one is due to be delivered today. With any luck, by the time my temporary power pole is set the pool will be ready or close to it.

It may be too late to ask this queston but just curious. If you plan to replaster almost immediately, why not drain the pool, drill you 4-5 vent holes (bottom of pool) and high pressure wash the inside. I understand the low water table but your vent holes should help prevent your pool from floating. That should drastically cut down on your expenses and perhaps upgrade to an aggregate pool finish.. :) :)
Re: Opening after Katrina
I am also in SE Louisiana (Prairieville/Gonzales area) and I am wondering how everything went with this...?
Did you get everything fixed up? Which route did you go and how does it look now? If you're still around, it would be great to have an update!
