Over time, fine particles settle at the base of the tank and form a sediment layer. In order to avoid swirling of the sediment layer by inflowing rain water, the water must be steadily supplied to the tank. The inlet calmer adds the rainwater to the tank without disturbing the sediment layer. Pumps and other parts of the system are subject to less wear and therefore have a higher durability.
