The waters that form on showers, the detergent water flowing from the basin, the air conditioning waters, the deck water, the rain water or the water flowing to the Sintineye are collected and stored in these shower tanks. The water in the shower tanks is transferred to the main sewage tanks and stored in the marina until the sewer suction is done. Thanks to the built-in filter, foreign materials such as dirt, buckles, hair that have escaped from the basin have prevented the pump or system from malfunctioning.
