About Pools

■safety measures

The swimming pool in Il Mare has a water absorption groove in the center and in front of the wave generator. This water absorption groove is fixed with dozens of bolts and we re-tighten the bolts periodically. Also, the water absorption rate is very gentle and does not suck hard. In case the lid comes off, please do not worry as there is no space for people to be sucked in and caught in the net.
