zappalot Posted June 11, 2017 Share Posted June 11, 2017 Our roughly 100,000 L swimming pool is about 25 years old. It is ready for renovation due to poor management in the last few years. About seven or eight years ago it was completely renovated. A high acidity level dissolved the grout. I am preparing this right now and figured out that our pool set up is as follows: the water from the swimming pool is flowing through the skimmers into a special storage tank that is located in between the swimming pool and the pump/filter system that is located in a room below/beside the swimming pool. The storage tank holds anywhere between 15,000 and 20,000 L of water. This storage tank was never taken care of and has about a 30 cm thick layer of sediments at the bottom of it. As of now this tank should be emptied from the water. My question is is there any need for this storage tank? I can't figure out for what this extra tank is for. Actually I just would connect the skimmer respectively this canal that is leading around the swimming pool directly with the pump/filter system. I mean the more water you have the more chemicals you need. And no one wants to take care the sediments in this storage tank. Link to comment Share on other sites More sharing options...

grollies Posted June 11, 2017 Share Posted June 11, 2017 Sounds like the pool was originally an overflow pool and has been converted to a skimmer-type. You can by-pass the tank and plumb the skimmers directly to the pump BUT you need to post a piping diagram here (or to a pool consultant) first to get a better idea of your system. If taking ideas from TVF, wait for a consensus of opinion, there are knowledgeable people here and I'm sure they'll be loads of advice. Link to comment Share on other sites More sharing options...
zappalot Posted June 11, 2017 Author Share Posted June 11, 2017 As soon as I had to look into the storage tank later today I will create a chart showing how the whole system is set up. Link to comment Share on other sites More sharing options...
carlyai Posted June 11, 2017 Share Posted June 11, 2017 Yes, was just going to say that and you beat me to it. Is there still an overflow recess all around the pool? You said there was a channel, but is it a working channel? If so, you have an overflow type pool with wall skimmers as well? If there is you may have 2 options: go with skimmer or overflow. I don't know much about overflow types, but a good main advantage I can see from swimming in a skimmer type and overflow type, is that when you are swimming in a skimmer pool, you are continually bobbing up and down because of the waves. I didn't notice this in an overflow type pool.This is just my opinion. Sent from my SM-J700F using Tapatalk Link to comment Share on other sites More sharing options...

zappalot Posted June 11, 2017 Author Share Posted June 11, 2017 Yes, I figured out the difference, we have an overflow style pool. But maybe we can reduce the size of this overflow storage tank from maybe 20,00 to 5000 Liters Link to comment Share on other sites More sharing options...

But maybe we can reduce the size of this overflow storage tank from maybe 20,00 to 5000 Liters NO the minimum size of overflow tank should be at least 10% of the total pool volume to be effective.If you reduce it you will have major problems. whilst the pool is circulating without bathers the tank should be around one third full, the rest of the void is taken up by displacement of water by bathers. Giving the recommended nos of bathers (instantneous bather loads) is easy to work out if you give me the area and depth of the pool. REMEMBER AS IT IS A COMMON USE POOL IE CONDO , RESORT, PUBLIC POOL THAILAND DOES HAVE BUILDING CODES FOR SUCH AND YOU AUTHORIZE ALTERATIONS AT YOUR OWN RISK. Please seek specialist advice from companies with the specialist knowledge . The forum sponsor is a good place to start. This is not any old backyard pool Link to comment Share on other sites More sharing options...

sappersrest Posted June 11, 2017 Share Posted June 11, 2017 From the picture you posted previously you indeed have an overflow pool. However It is indeed essential to have skimmers with an over flow pool when you have a freeboard abutting the pool i.e. a feature wall. or raised walkway more photos please.

sappersrest Posted June 11, 2017 Share Posted June 11, 2017 1 hour ago, Naam said: no need for specialist advice cleaning out decade old dirt from an overflow tank. Hi I really meant seeking advice about altering the hydraulic setup of the pool inc reducing the balance tank. You do however raise a very good point about specialists cleaning out balance tanks. (they are not overflow tanks) They are extremely dangerous places to enter, without specialist knowledge and training. Persons in the past have become seriously ill and have collapsed in these tanks due to lack of oxygen. One of the easiest ways to dose chemicals into these pools is infact to lift the gratings nearest the drop pipe and put the chemicals in there. Whilst this is an easy way out it appears to some operators to be the way of doing it. So we get to the point of say a manager or maintenance team decide it needs cleaning. So they pump out the tank or drain pool and decide to send poor Somchai down with a broom and shovel, hey presto he collapses and dies. Pool balance tanks are dangerous places Pool balance tanks contain the residuals of undiluted chemical whilst they are ok when they are covered in water once the covering of water is removed the fumes given off become toxic and decrease the level of oxygen. there are also high levels of combined chlorine in the air and more than likely nitrogen try chloride, tear gas to us. Do not enter a balance tank unless it is properly vented , forced air for a long period of time usually 4 hours. And that there is an adequate monitored air supply. A manager or condo committee do have a duty of care to the staff they employ contractor or otherwise If for some reason you do send Somchai down there and he collapses do not attempt a rescue call the emergency services. There is plenty of info on the net regarding confined space working. Link to comment Share on other sites More sharing options...
