Retention tanks are covered, underground watertight tanks with an outlet, used to retain rainwater for further use, such as watering, for technical purpose or without any use with a controlled outlet option. RT serves to decrease the water run-off from an area. Water run-off control can be done either using a run-off controller or a pump. Reinforced concrete tanks are made of C 30/37 Class concrete. The ceiling slab/tank joint is sealed with a rubber gasket. The ceiling slab is screwed to the tank using screw connections. The connection is watertight and permanently elastic. RT can consist of one tank or, if larger retention volume is needed, can have several interconnected tanks. The individual tanks are interconnected with PVC pipes via transitions and rubber gaskets that are inbuilt into the tanks during manufacture. Such transitions are completely watertight and their assembly is very easy and fast.
