BLUESPRING COMPENSATION SYSTEM
In traditional overflow pools, so that they can work properly, you need to create an external water collection tank to the pool called the compensation tank, that take care of keeping constant the level of water, collecting the excess and returning it when needed. This container needs to be covered on top and can be accessed only by qualified technical personnel for routine and extraordinary maintenance operations. Normally this tank is made completely underground in reinforced concrete.
If we imagine that in a swimming pool 5 x 10 meters, which contains approximately 65 cubic meters of water, immerse themselves at the same time 6 persons, from the basin of the pool about 0.6 cubic meters of water will come out , which have to be collected by the overflow tank and then being returned to the pool when the swimmers will come out of the water.
In such a situation in traditional overflow a pool it is therefore necessary to build a compensation tank external to the pool, which must have the capacity of at least 7% of the total volume of the pool to which it is coupled, thus raising at least 15-20% the costs of the civil and hydraulic works necessary, not to mention the costs of maintenance of the one that is in effect a second pool to realize and maintain.
With Bluespring all this is not necessary, thanks to the use of big and capacious overflow duct, which allows to avoid the construction of the external compensation tank, with consequent and evident of space and cost savings.
